The deepest image of universe ever taken- Hubble Space Telescope

The Hubble space telescope is the most famous telescope in the world. It was named after the famous astronomer Edwin Hubble who changed our understanding of the universe proving the existence of other galaxies. It is an automatic observatory, has discovered millions of new objects in space. It helped us to witness the birth of new stars, found planets outside the solar system and see super massive black holes. Hubble was launched in 1990, and from December 1993 to may 2009, the telescope was repaired and updated four times. Astronauts visited HST five times in order to make repairs and new instruments.

Hubble holds the record for the longest range of observation. The light from the most distant galaxies has taken billions of years to travel across the universe and reach Hubble. By taking this picture, Hubble was literally looking back in time to the very early universe. You can notice on the right side of the image, there is a galaxy very much like the Milky Way that galaxy is about five billion years away, so we are looking back in time by five billion years. In March 4^th, 2016, NASA releases a historic image, one that many believed was impossible. It captured the farthest away of all known galaxies; it’s located about 13.4 billion light years away from us. The light from his galaxy has just reached the earth crossing the distance that separates us; hat is now we can observe it as it was 400 million years after the big bang. This galaxy is 25 times smaller than our galaxy, the Milky Way. It helped to find the age for the universe now known to be 13.8 billion years, roughly three times the age of earth.

This view of nearly 10,000 galaxies is called the Hubble Ultra Deep Field. The snapshot includes galaxies of various ages, sizes, shapes, and colours. The smallest, reddest galaxies, about 100, may be among the most distant known, existing when the universe was just 800 million years old. The nearest galaxies – the larger, brighter, well-defined spirals and ellipticals – thrived about 1 billion years ago, when the cosmos was 13 billion years old. The image required 800 exposures taken over the course of 400 Hubble orbits around Earth. The total amount of exposure time was 11.3 days, taken between Sept. 24, 2003 and Jan. 16, 2004.

With the advanced camera of the NASA’s Hubble space telescope, it discovered a new planet called Fomalhaut b which orbiting is parent star Fomalhaut. Fomalhaut is 2.3 times heavier and 6 times larger than the sun around it is a disc of cosmic dust which creates the resemblance of an ominous eye. Fomalhaut b lies 1.8 billion miles inside the ring’s inner edge and orbits 10.7 billion miles from its star. Astronomers have calculated that Fomalhaut b completes an orbit around its parent star every 872 years. The Fomalhaut system is 25 light years away in the constellation Piscis Australis. But in April 2020, astronomers began doubting its existence; the planet is missing in the new Hubble pictures. Scientists believe that this planet was a cloud of dust and debris formed as a result of a collision of two icy celestial bodies.

**Fomalhaut** – The the **brightest star in the constellation** of Piscis Austrinus

In 1994, Hubble captured the most detailed image of the iconic feature called the pillars of creation. The pillars of creation are fascinating but relatively small feature of the entire eagle nebula. The blue color in the image represent oxygen, red is sulfur, and green represents both nitrogen and hydrogen. The nebula was discovered in 1745 by the Swiss astronomer jean Philippe Loys de Cheseaux, is located 7,000 light years from earth in the constellation Serpens. During its work Hubble has presented millions of images but unfortunately NASA has suspended missions to repair and modernize the telescope. It is assumed that in 2021, Hubble will be replaced with the new James Webb space telescope.

OBSESSION

The people of India have a special love for the language of English. With it being one of the official languages of India, people have obsessed over it now for years. It is considered supreme to any other local or regional language, the language of the elites, the language of the educated, the language of the rich, the language of the better, the language of the greater. Why the knowledge of an alien language has been recognised as the mark of standard or class? Why do Indians take pride in celebrating the English language more than any other? Why do the older generations boast about their children being able to speak English so much? Why do Indians being proud about their culture, traditions, ethnicity, customs and festivals are not as proud of their mother tongues as they are of English? These questions pop up every time a non- English speaking person is humiliated or belittled for their poor English speaking skills. But the real question is do we really need this toxicity of humiliating someone just for the sake of a mere language? No, absolutely we do not.

The answers to all these questions go back to the pre independent era. Ever since the British ruled over India they started with the policy of rejecting non-English, non-white, natives so as to establish strong foot of their supremacy. They dented the minds of naive Indians with the theory that only English speaking, white, educated (the western way) people were supreme and had the capability of ruling over others. With decades of humiliation and degradation, the people in pre independent India accepted the superiority of the English language and this made them bound to have inferiority complex about their very own language and mother tongue. The effect was so profound that even after independence, the people educated in English were considered better than those who were equally skilled but not in this supreme language. The Indian population were now interested in educating their children in an English medium school. The liking for the society with English read people enlarged to a level that it lead to the decay and ultimately the end of traditional schools with Indian native languages.

As India’s economy started to grow and new industries and establishments were born, the culture of hiring mostly and after some time only English speaking people grew to an unexpected level. The new businesses wanted English conversing people as they were now associated with better intelligence and know how. When we look back into the history of the relation between English language and the skills or expertise or wisdom we do not find any strong logical evidence to support that. It was merely the supremacy of the language created by the British that Indians starting judging themselves on the basis of the English speaking skills. The interviews were taken only in English language so as to ensure their hold of the language. Students with better grip of this foreign speech were preferred over others. Even this lingo came to be recognised as the symbol of intelligent, sincere and best for any job students.

Society made it very clear with their over likeness towards English that only the privileged, classy, affluent and powerful individuals could afford and were entitled to this learning. This obsession with a foreign tongue was so unhealthy and unwanted that till this day citizens of India have not been able to accept the fact that it is just a language and that the understanding of this speech has nothing to do with intelligence or wisdom. The folks with lesser experience or practice in English are judged too quickly as being the lesser ones. There is a swift shift in people’s attitude after they realize they are conversing with someone with no skills for English language than with the one who is an expert in it. Though with developing nature of the society today, the respect and glory of the local, regional or native language that was lost decades ago is returning back but nevertheless the tilt towards the English language continues, bent enough to stay an obsession.

How advanced are Alien civilizations? -The Kardashev scale

The observable universe is consists up to two trillion galaxies that are made of billions and billions of stars. In the Milky Way galaxy alone, scientists assume that there are some 40 billion earths like planets in the habitable zone of their stars. When you look at these numbers, there are a lot of possibilities of alien civilization to exist. In a universe that big and old, the possibilities of civilizations may start millions of years apart from each other, and develop in different directions and speed. So their civilization may range from cavemen to super advanced. We know that human started out with nothing and then making tools, building houses, etc. we know that humans are curios, competitive, greedy for resources, and expansionists. The more of these qualities that our ancestors had, the more successful they were in the civilization building process.

Like this, the other alien civilizations also might have evolved. Human progress can be measured very precisely by how much energy we extracted from our environment. As our energy consumption grew exponentially, so did the abilities of our civilization. Between 1800 and 2015, population size had increased seven fold; while humanity was consuming 25 times more energy. It’s likely that this process will continue into the far future. Based on these facts, scientist Nikolai Kardashev developed a method for categorizing civilizations, from cave dwellers to gods ruling over galaxies into a scale called the Kardashev scale. It is a method of ranking civilizations by their energy use. It put civilizations into four categories. A type 1 civilization is able to use the available energy of their home planet. A type 2 civilization is able to use the available energy of their star and planetary system. A type 3 civilization is able to use the available energy of their galaxy. A type 4 civilization is able to use the available energy of multiple galaxies

. It’s like comparing an ant colony to a human metropolitan area. To ants we are so complex and powerful, we might as well be gods. On the lower end of the scale, there are type 0 to type 1 civilization. Anything from hunting, gatherers to something we could achieve in the next few hundred years. These might actually be abundant in the Milky Way. If that possible, why they are not sending any radio signals in space. But even if they transmitted radio signals like we do, it might not be very helpful. In such a vast universe, our signals may extend over 200 light years, but this is only a tiny fraction of the Milky Way. And even if someone were listening, after a few light years our signals decay into noise, impossible to identify as the source of an intelligent species. Today humanity ranks at about level 0.75. We created huge structures, changed the composition and temperature of the atmosphere. If progress continues, we will become a full type 1 civilization in the next few hundred years. The next step to type 2 is trying and mine other planets and bodies.

The Dyson sphere – mega-structures built around sun to draw energy

As a civilization expands and uses more and more stuff and space, at some they may start a largest project that extracting the energy of their star by building a Dyson swarm. Once it finished, energy has become unlimited. The next frontier moves to other stars light years away. So the closer a species gets to type 3, they might discover new physics, may understand and control dark matter and energy, or be able to travel faster than light. For them, humans are the ants, trying to understand the galactic metropolitan area. A high type 2 civilization might already consider humanity too primitive. A type 3 civilization might consider us bacteria. But the scale doesn’t end here; some scientists suggest there might be type 4 and type 5 civilizations, whose influences stenches over galaxy clusters or super clusters. This complex scale is just a thought experiment but, still it gives interesting things. Who knows, there might be a type omega civilization, able to manipulate the entire universe, and they even might be the actual creators of our universe.

Pollution a reality of today

Pollution has became a part of our life. It has became the reality whether we accepted or not. We have to now keep air purifier to purify the air inside our house. Just think of the level of destruction in has caused to just as well as to nature.

We have reduced the resources of nature or either we have misused the resources of nature for our own benefit. We youmans are so selfish that for our benefit we can even take away the things which are meant for everyone. Like we have polluted so many rivers which has caused death to so many aquatic animals that we can’t even imagine of.

We have polluted the air quality so much that we are now facing difficulty to breathe ourselves. We have caused pollution in air, water, soil, noise whatnot. Just think it yourself.

Now there are so many activist and NGOs are coming ahead for cleaning up the message that has been spread by us only. But it is not enough. To remove Facebook devil from our mother nature each and everyone have to contribute towards this.

We can take small steps like using public transport instead of personal one for travelling which will reduce the air pollution. There is no need of very much big-big steps to be taken a small step by each individual is enough for cutting this pollution into half.

It is our nature and we should use net sustainabily so that it is available for other animals and future generation as well.

Education a right of everyone but a gift for poor

Education the solution for every problem in this world. If you are educated you know how to manage difficult time in a better way then others. Education is not only provided in school but it also present all around you.

The context of education is very wide, you can’t say that education is only provided in schools and colleges. By education you’re mean that you learn from your surrounding not only bookcase knowledge. A person who never went to school doesn’t mean that he don’t have knowledge of anything.

At present to the covid-19 situation there are millions of children who had lost the access to education, because they are not having digital devices to have their online Classic in even their schools are shut off.

Today we are having so many excuses for online classes like we’re having strain in eyes, neck, headache etc. I don’t mean mad they are not genuine but, these are not as hard as you are not getting education. You are fortunate in now to continue your education even without going to school but many in this world a not so fortunate.

There are many example synthesis world who had sacrifice a lot just to get educated. One of them is Malala Yousafzai who was ready to get shot from gun just to get educated.

So whenever you feel like you don’t want to study just think about them and you automatically will get an inspiration and a sense of gratitude that you are having so many resources that your education is not getting any hindrance.

We and government together should take step that gift access of education to everyone in your country or in the world. We can donate our old book, pencils and other stationaries to them and that will be a small step from our side but will make a big difference for them.

Why the long face? The Scream

The Scream is one of the most famous artworks on the planet. Almost everyone of us must have seen it somewhere or the other. Either in memes or maybe on some educational TV channel but very little population knows the name of the artist or even the name of the painting itself.

Edward Munch

The Scream is an artwork by the Norwegian artist Edward Munch completed in 1893.

Munch was a painter and printmaker born in Norway in 1863. His paintings were greatly inspired by the expressionism movement and symbolism. All his paintings had a certain underlying psychological tone to it which is hard to miss. Munch had a miserable childhood, and that misery manifested itself later in his paintings. His mother and sister died of tuberculosis while he was very young and later, still at a young age he lost his father and his brother too. Death and gloom always meandered around him and followed him everywhere. Another sister of his suffered from mental illness too.

To understand a piece of art it is important to understand the artist, his experiences, his life to be able to get as close to meaning the artist was trying to show because there is no possible way that we can fully understand an artist’s psyche at the time of making it even though art is interpretive.Munch depicted raw and violent emotions in his work

The scream is an autobiographical work of art where while he was walking along a path one evening with a fjord below, feeling tired and ill, when looked over the fjord the scene looked to him as if blood was covering the sky. He felt a scream coursing through the clouds. Munch had a history of ill mental health in his family and during that evening it is possible that he heard the scream inside his own head.Soon after painting The Scream abandoned this style and barely went back to it.

Theft

A work of art doesn’t become famous just because of the beauty or the skill behind it but a multitude of things influence it’s popularity like what it represents, political environment, controversies it was involved in.

Similarly this painting is not just famous for its artistic grandeur but it was in the news a lot due to the thefts.

In 1994 thieves broke into a museum in Oslo and stole the painting also leaving a note that read thanks for the poor security and demanded 1 million USD as ransom which was refused. About 3 months later the two men were caught as a result of the sting operation carried out by the Norwegian police.

In 2004, a 1910 version of The Scream was stolen from the Munch museum in broad daylight by two masked gunmen who stole The Scream and Madonna by Munch. The Munch museum was closed for 10 months after the incident for security reasons. It took about 2 years for the Norwegian government to recover the two paintings with some major damage to the paintings which were recovered later.

Mother Tongue

Nowadays we are more on speaking in English rather than choosing our own mother tongue for communication, especially in India. This post is not discourage English language but encourage mother tongue

If you are an Indian then definitely your mother tongue is not English, and mind you here I am talking about those Indians who are living in India and I want to Indian parents, not of migrats. You might be speaking Hindi Tamil Punjabi Gujarati Asami Bengali etc. English has now become a language more of showing status rather than just being a medium of communication.

We use our mother tongue only while speaking to family members. All the other official work Arjan in English which is alright because India has very diverse population having different languages. But the problem is where we treat English as as a measurement tool for checking someone intelligence.

We prefer to speak in English in interviews as to give a better impression on the interviewer that you guess we know English and we are intelligent. A person who is living in a remote village can also be has equally qualified and intelligent as the person who knows English but, just because he don’t know how to speak English he is not getting that equal treatment while he goes for any job employment. And this is a reality.

We think in our mother tongue will our comfortable in speaking our mother tongue it’s just that we don’t use it because of the societal atmosphere around us. Through this post I just want to encourage people to be proud of their mother tongue and speak it with their heads up and not to treat english as a qualification of intelligence.

It is a fact that if you think in your own mother tongue then you are getting more effective and innovative ideas.

How we measure extreme distances in space – Light years

In the 1800s, scientists discovered the realm of light beyond what is visible. The 20^th century saw dramatic improvements in observation technologies. Now we are probing distant planets, stars, galaxies and black holes where even light would take years to reach. So how we do that? Light is the fastest thing we know in the universe. It is so fast that we measure enormous distances by how long it takes for light to travel them. In one year, light travels about 6 trillion miles. It is the distance, we call one light year. The Apollo 11 had to travel four days to reach the moon but, it is one light second from earth. Meanwhile, the nearest star beyond our own sun is Proxima Centauri but, it is 4.24 light years away. Our Milky Way galaxy is on the order of 100,000 light years across. The nearest galaxy to our own, Andromeda is about 2.5 million light years away.

The question is how do we know the distance of these stars and galaxies? For objects that are very close by, we can use a concept called trigonometric parallax. When you place your thumb and close your left eye and then, open your left eye and close your right eye. It will look like your thumb has moved, while more distant objects have remained in place. This same concept applies in measuring distant stars. But they are much farther than the length of your arm, and earth is not large enough, even if you had different telescopes across the equator, you would not see much of a shift in position. So we look at the change in the star’s apparent location over six months, when we measure the relative positions of the stars in summer, and then again in winter, nearby stars seem to have moved against the background of the more distant stars and galaxies.

But this method only works for objects less than a few thousand light years away. So, for such distances, we use a different method using indicators called standard candles. Standard candles are objects whose intrinsic brightness, or luminosity that we know well. For example, if you know how bright your light bulb is, even when you move away from it, you can find the distance by comparing the amount of light you received to the intrinsic brightness. In astronomy, we consider this as a special type of star called a Cepheid variable. These stars will constantly contract and expand. Because of this, their brightness varies. We can calculate the luminosity by measuring the period of this cycle, with more luminous stars changing more slowly. By comparing the light that we received to the intrinsic brightness we can calculate the distance.

The Type 1a Supernovae – Death of a star

But we can only observe individual stars up to about 40 million light years away. So we have to use another type of standard candle called type 1a supernova. Supernovae are giant stellar explosions which is one of the ways that stars die. These explosions are so bright, that they outshine the galaxies where they occur. So we can use the type 1 a supernovae as standard candles. Because, intrinsically bright ones fade slower than fainter ones. With the understanding of brightness and decline rate, we can use the supernovae to probe distances up to several billions of light years away. But is the importance of seeing distant objects? Well, the light emitted by the sun will take eight minutes to reach us, which means that the light we see now is a picture of the sun eight minutes ago. And the galaxies are million light years away. It has taken millions of years for that light to reach us. So the universe is in some kind of an inbuilt time machine. The further we can look back, the younger we are probing. Astrophysicists try to read the history of the universe, and understand how and where we come from.

“Dream in light years, challenge miles, walk step by step” – William Shakespeare

World of Social Media

Social media a word which is is now probably used by everyone. Social media maybe your WhatsApp, Instagram, snapchat, Facebook etc. These are some of the name of the apps which helps us to interact with whole world.

The power of social media in today’s world cannot be neglected, as there are many examples present where a small startup has grown into big business firm and because of a small post once put on some of the social media apps.

It not only help businesses to grow but it also helps your ideas to reach too many people around the world. It provides you a platform to give voice to your ideas and thoughts. Some of the other social media platforms like LinkedIn helps to create professional relationship.

It has helped each individual to showcase the talent. Earlier days the people who want to actually act in front of the audience were only limited to the film industry but, now even the common people can post their videos in any of the social media platforms like YouTube, Instagram, Facebook etc.

As we know everything has two sides so, it is also having its Dark Side as well. Today’s youth has now started misusing the social media platform for just waste of time. Day spend a lot of their valuable time just watching wasteful videos for chats. By this I don’t mean that you should not watch videos to refresh your mind you should watch but there should be a time fix for it.

We should always look at the positive thing in life to go ahead, so it similarly applies to the social media too. We should focus on using it positively so that it brings about a change in society in good manner and as well as in yourself as a person by gaining knowledge from other people.

Feelings

Do you have any idea what feelings actually are? There are people who know it, there might be people who don’t know. Feeling are actually your true personality.

Feelings actually represent your true personality. Like for instance we know many people around us cry by Justin emotional scene in the movie, what does it represent? It represents that they are soft hearted people it’s a part of the personality, they are emotional.

And in this world you cannot actually categorise feelings because in human there are so many types of feeling that we can’t even express many of them. We have sometimes very weird feelings that we can’t even express them. Just think it yourself you might be having such feelings at some point in your life.

A feeling of joy, a feeling of happiness, a feeling of sadness, a feeling of embarrassment etc. The list goes on and on and on. Here we meet categorised feeling in some of the specified sections, but the reality is that they are really very vast.

Sometime we have combinations of feelings together that we can’t give it a new name. And in reality your personality e is Defined by how you feel about each and everything around you. Feelings are a part of your thoughts. How we think of each and everything, ultimately develop feelings in everybody. That’s why everybody have different feelings in a same situation.

True Friends

Friend word which when you herd make you smile. Friends are the only one whom we choose ourselves. They are the ones with whom we share our feelings.

They are the ones with whom we spend our time by our own willingness. True friends are the ones who are always ready to help you at any point of time in your life. True friends are not made for benefits they are made for sharing feelings.

They are the ones with whom we fight a lot but never let another person dare to fight with them. They are the ones who understand your feelings in your weak times. No matter whatever happens they are always with you even if the whole world is against you.

True friends are like treasure you can’t easily find them but if you found them then and there always by you. That’s why everybody in this world says that finding a good friend is really very difficult in this world.

Friendship is also a relationship of respect, trust and gratitude. You play with them, have fun with them, play pranks on them and always help them. But choose your friends wisely as in today’s time everybody is two faces and you have to find the true face of a person with whom you want to be friends with.

Power of Time

You had heard of the film ‘No time to die’, you have heard of the phrase ‘no time to waste’, you had heard of people saying ‘time is money’. From all these examples you have understood that time has very much importance in our life.

Have you ever thought that something which is not even visible have so much importance in our life. Everybody says this one thing that the person who knows how to manage his time knows all the secret of success.

Time management has gained so much importance in today’s world that there are even courses to let people learn and understand how to manage their time. This is the one thing which we have to follow as we all know that time never follows anyone or stops for anyone.

This is the one thing which everybody has in eaqual amount, whether you are rich poor lives in America India anywhere in this world you all have a 24 hour in a day. The thing which make time different is how we utilise it.

We all know that the strongest thing in this world is time. We all should understand and utilise at a time in useful things. And by this way I am not saying that you should not have a relaxing time what time for your hobbies you should absolutely have those time. You should have time for everything in life. And you should do all the thing at the right time.

About that artist- pablo picasso 1

Pablo Picasso was a Spanish painter, sculptor, ceramist and printmaker born in 1881, in Malana, Spain. His impact on art is huge. He is one the most renowned artists in the world, who left a mark for himself in the history of art and founded a movement in that he most known for, cubism

Life

Pablo Picasso was born in malana in 1881. His father was a drawing professor, this could be one of the reasons why Picasso was inclined towards art at the young age of 10. In 1981, their family moved to A Coruna, in 1891, where his father began teaching fine arts. At the age of 13, his father saw one of his paintings and was so impressed that he thought his son had surpassed him.

Four years later the family moved to Barcelona, after the death of his younger sister. In Barcelona, Pablo joined a fine arts school where he excelled but his father knew that he won’t be able to fully reach his potential in Barcelona. Therefore, about 4 years later his father sent him to Madrid to pursue his art.

Career

Pablo was painting professionally from a very young age. The First Communion (1896), Portrait of Aunt Pepa (1896) are the paintings that he completed at the age of 14.

In Barcelona, he barely attended classes, he would wander in museums and admire the works of other artists like Rossetti, Steinlen, El Greco. In 1900, he held his first exhibition in Barcelona, which featured around 50 of his artwork and was well appreciated for it.

The same year he made his first visit to Paris where he discovered some of the greatest things, some great colors, colors of Vincent van gogh rendering him extremely impressed.

The Blue Period

This was a time during which Pablo Picasso used blue as the more prominent color in his paintings. This lasted between 1901-1904. This period in Picasso’s career can be attributed to the death of his friend Casagemas who had shot himself over a girl. He painted various portraits of Casagemas that had sort of a pang of grief and the observer could feel it.

Some of the paintings from the blue period include The Soup (1902), La Vie (1903), The Old Guitarist (1904). All these paintings possess a great deal of sorrow and the blue color makes it appear even more gloomy.

The Rose Period

Even during the blue period, Picasso travelled between Barcelona and Paris, but in 1904 he moved permanently to paris. This and many other incidents in his life inspired this period. During this time he used lighter shades. Some of the rose period paintings include Two Nudes (1906), Woman with Loaves (1906), Garçon à la pipe (1905).

Cubism

Cubism is an art movement that became prominent during the 20th century. It represents reality in the form of cubes often making it appear distorted and fragmented. Picasso is considered one the founders of this movement and he truly made it his.

These are the types of paintings that Picasso is most known for.

Sports

Sports happy way to stay fit. Sports has now change the way we live. Sports help us to stay fit while you are having fun. Playing sports also improve your personality and give few more skills.

Sports teaches us the sportsman spirit. It helps us to build a teen spirit among us. It’s such childhood pleasure. It’s time when we forgot our all worries and just focus on a happiness and on the sport.

It helps us to increase our concentration power as well. It helps us to stay fit, and from the word that I mean both mental as well as physical fitness. Value place port you doesn’t need to go to gym and all the stuff wish you don’t like to do.

It’s just not academic that is important being is sports is equally important. Being in sport doesn’t mean that you have to be a professional or a very good clay for it you can just played for your happiness your leisure time, just for fun.

It bills a healthy competition environment. It helps us to stay away from mental diseases like depression, anxiety, stress, etc. It teaches us some really important lessons in a life like how to be optimistic, there is always another way for any problem, there is always something good at the end, if you lose by one score that doesn’t mean you are not good it’s just the luck and you have to try for the next time.
