It would seem that the Sun had missed the «demographic explosion» that hit the Milky Way some ten billion years ago. At the time, stars formed 30 times faster than they do now. The Sun is a «late bloomer», which formed five billion years after the average star formation speed had already decreased.

These are some of the results published in NASA’s April report that includes a model of an «early» Milky Way compiled using 2,000 images of galaxies similar to ours. Images taken by multiple telescopes stationed on Earth and in space, including the popular Hubble Space Telescope, helped shape a trip to the past.

Hubble Space Telescope, which has been in orbit for 25 years, has contributed much to the development of technologies that allow scientists to look into the farthest corners of the Universe and expand human knowledge. One of the historic images taken by Hubble Space Telescope is the so-called dark field, which is a small, previously considered empty segment of the cosmos that shows previously unknown galaxies far away. In order to ‘catch light’ coming from unknown objects, the telescope was redirected toward this segment for ten days a row.

In 2012, astrophysicists once again tried to study this unknown segment of the cosmos using modern equipment. Research yielded 5,000 previously unknown galaxies. Some of them formed approximately 470 million years after the Big Bang.

Another shocking discovery was made by astrophysicists in the centre of the Milky Way. Researchers discovered that this peaceful and partially dead region actually hides clusters of newly-born stars.

The Hubble Space Telescope named after Edwin Hubble, an American cosmologist, is a real research laboratory in Earth’s orbit. The 13-metre-long and 12 ton research laboratory is built in modular fashion. This allows it to function longer than other space stations. It can also be upgraded with latest equipment. Recently, NASA and ESA have developed 15 special scientific instruments for Hubble Space Telescope.

  1. Breaking news by Nida Elena Lukosiute says:

    Scared Sandra Bullock isnt wise to say that Tragedies bring out the best in people. Tragedies bring lots of negativity and problems with justice theory. As a star you can say a lot, but dont forget to dig deeper in the psychology and how different people react differently to the consequencies of tragedies. What you were trying to say about the intelligence? My advice: Analyse yourself before the sleep and dont call to your ex boyfriend even if you feel smashed. When you were starting to kiss women I thought your personal relationship tragedy has made you a lesbian.

    Think and think, maybe the sun will lighten the brain and society will stop being influenced negatively by celebrities that bring lots of tragedies and bad advices, not opposite as the mass likes to think.
    The words of the stars are so important for the mass, that its advicable to criticize them.

    Later investigating whose fault, dont give interview about your personal life details, its your choice, stop blaming magazines. Control yourself before you give any advice. I used to like you as an actress in Denmark when I was 24, but those days are gone and honestly you cant save the world with your pfilosophy.

    Keenu Reeves not my type man that I will announce him the sexiest, but the best paid. I was in shock, but really happy that he is alive. I am very strict, so what, because my tragedies make me very critical and I dont like that smile, which really means: why dont you die, get punked, embarrassed, sick, so use smily tactics.
    The movie Matrix is one of my favourite and I am happy to know that it has become the best movie of all times.
