The space and their mystery.
When we look at the sky, we do not think of all the mysteries that our universe can hold, a place with 13,800 million years old and with an extension of 150,000 million light years in diameter.
- mobile stars
In 2005, astronomers discovered the first "moving star", which moved through the galaxy at a speed ten times higher than normal, at about 900 kilometers per second. Scientists have established some hypotheses about what drives these few stars in space, but they have no certainty. It could be the explosion of a supernova or a supermassive black hole.
- Black holes.
For now, astronomers do not know anything as strange as a black hole.
Nothing can leave the gravitational limits of a black hole: neither matter nor light. Astrophysicists believe that they are born from dying stars with a mass equivalent to between 3 and 20 suns. The mass of black holes in the centers of galaxies can exceed 10,000 to 18,000 million times the mass of the sun . They grow by absorbing gas, dust, stars and other smaller holes.
- POINT OF VIEW:
The space is big but we are satisfied with what little we know.
