Give Me 10 Minutes, I'll Give You 5 facts about Stars

Stars are known to be the dominant feature of the universe and are only filled with mysteries and questions. Here are some of the most amazing mysteries about stars that will blow your mind!

1. The star that's there but shouldn't be there.

The star in question is called "SDSS J102915+172927" and like its name the existence of the Star is more complex than you think. This star has been known to exist for 13 billion years and according to theories it shouldn't even exist as the universe itself is known to be 13.8 billion years old. 13 billion years ago there was just gas and debris in space so its difficult to wrap our head around the existence of a star. Since the star did exist during the time this would also mean that the earliest planets revolved around this very star.  

2. Not all stars are hot

NASA has found 14 stars that have extremely low temperatures. These stars are known as failed stars because well they could not develop after the Big bang. Their low density prevents these stars from fusing atoms within their cores. The heat generated from every star directly depends upon the rate of fusion occurring at its core. Since this doesn't take place on these cold stars, no heat is generated. Finding such a star is extremely rare and can only be seen in spectrums beyond the human eye i.e. Ultraviolet or Infrared. So the next time when somebody says that all stars are hot you can use this to counter their argument.

3. Stars formed from Stars

According to theorists before the big bang there existed a similar universe like ours. This universe had seen its end and had collapsed into one big star. What happened after this led to the big bang. So you could say that the stars we see today are the creation of the stars that were there in another universe before the big bang. 

4. Blackholes form from stars

We know that a collapsed star forms a black hole but what exactly happens. When a star collapses it has basically lost all its energy and it throws its energy into space. Accept sometimes there exists a gravity on this dead star that has the tendency to pull back this energy of the now dead sun. Most of the time this energy wraps around the dead star to form a spiral but if the energy falls back on the neutron star, a black hole is formed. The sun gets destroyed because of its own energy. This is known as the fall back. Its like throwing an object towards the sky on Earth and it comes back down. 

5. Stars in the sky aren't where they are seen

If the star was moving away it would only be visible in
Infrared. Otherwise it is visible in the Ultraviolet spectrum.

Space is expanding faster than the speed of light and it is causing Stars and everything in the universe to move. This means that stars are continuously moving in Space and what stars you see now are just the light that remains of the Star. The star itself has moved ahead. So what you see today might have been the position of the stars a few million years ago. Yes you read it "MILLION"!

Stars are everywhere in the Universe. Humans have only looked at a handful of stars in the universe but the amount of information from these stars has been ground breaking.
