Astronomy Science ~ More recently, scientists have claimed that red dwarf is the most stars in our galaxy, might host habitable planets though its mass is not more than 20 percent of the mass of the sun. But a new study warns that the world 'Earth-like' we've seen in the star's habitable zone is no more than an illusion (mirage) - because of the intense radiation they received at the beginning of the planet formation.

This study claims that the 'Earth mirage' will look like our planet from a distance, but if we peek deeper, this planet will show a barren world with no water or no life on its surface. This research was conducted by astronomy graduate student and assistant professor Rodrigo Luger Rory Barnes of the University of Washington. They studied red dwarf star which is also known as the M. Star this type fills 75% of all stars in our galaxy.

In their study, the researchers found that the early life of red dwarf stars far more active. This happens in most stars, but but a red dwarf take longer because they are much smaller. This means that the planets formed about 10 million years after the formation of stars, they will be at the brunt ering star to star activity was quiet which requires a very long time.

Each time the water on the planet would be boiled by the intense heat of its star.

And the Earth-based observations of astronomers, the water will be split into hydrogen and oxygen atoms. This phenomenon will produce great atmosphere full of oxygen and from afar, it looks like a habitable planet. But if we take a trip to the planet's, it will reveal the fact that the planet is dry because he has long lost its water. This gave him the nickname as Mirage Earth.

"Because they make oxygen, they can look like the Earth from far away - but if you look closer, you will find that they are only a mirage; there was no water there," said Mr. Luger. He added that "a lot of planets in the habitable zone of a red dwarf star could be dried by this process since the beginning, greatly reducing their chances of actually be livable."

The researchers say that the atmosphere on the planet could be 10 times more dense than the atmosphere of Venus and could "mess up our search for life on exoplanets."
