Detecting planets that have life outside the Solar System

Astronomers have found the first evidence of outer-life planets outside.

This discovery begins with astronomers finding the body of an asteroid. Accordingly, this asteroid has a large amount of water - an extremely important factor for life. That shows that hundreds of millions of years ago, there existed planets like Earth.

The study participants believe that the discovery is a new step forward for the future of humanity by anticipation, over several billion years,.

Professor Boris Gänsicke, of the Department of Physics at the University of Warwick (UK), said: " This is the first time we have found a stone-made planet with water outside our Solar System. This means Earth-like planets exist - two components - rock and water surfaces - are key in finding a life-sustaining planet outside the System. So this is a really interesting discovery. "

However, he said it was still too early to speculate whether the planet had alien life, and if it ever existed, it was unlikely that they would migrate due to the destruction of the sun.

To carry out the study, astronomers used NASA's Hubble telescope. Thus, they can observe the light emitted by GD 61 - an area 150 light-years away from Earth.

The corpses of asteroids were found to include dust and debris from which scientists have discovered chemical components such as magnesium, silicon, iron and an adequate amount of oxygen to prove it. once had water on this asteroid.

Our Earth is basically a "dry" planet, with only about 0.02% of the mass made up of surface water. The oceans were only formed later. Their formation may be the result of collisions between the Earth and comets or with water-rich asteroids.

Astronomer Jay Farihi, of the Cambridge Institute of Astronomy (UK), said: "Detecting the existence of water in an asteroid means the building blocks of life-like planets used to be exists, and may still exist in GD 61 area ".

According to NASA's latest estimates, there may be about 60 million planets in the universe. In order for life to exist on a planet, it needs to be in the habitat of a star close enough to allow water on the surface to be liquid. If the distance is too close, the water will evaporate, otherwise, if it is too far away, the water will freeze.
