Discover planet full of water

Astronomers have discovered a planet outside the Solar System that can hold more water than Earth.

BBC said, the planet, named GJ 1214b , was discovered in December 2009 by underground telescopes but astronomers only knew it was bigger than Earth and smaller than Jupiter. It is located in the constellation Ophiuchus and is 40 light years from the earth. The latest data sent by Hubble Space Telescope shows that it is very likely that water accounts for a significant proportion of the material composition of GJ 1214b.

"GJ 1214b is not like any other planet we have ever known. It is possible that a large part of its material is water," said Zachory Berta, a researcher at the Smithsonina Astrophysics Center at Harvard University. in the US, speak.

GJ 1214b revolves around a red dwarf at a distance of two million kilometers.

The diameter of GJ 1214b is 2.7 times the diameter of the earth, but its mass is up to 7 times the globe. It revolves around a red dwarf star about two million kilometers away. At that distance the planet's surface temperature can reach 200 degrees Celsius.

In 2010, scientists published the results of the GJ 1214b atmosphere study. The results show that its atmosphere contains a vapor-like substance. It may be steam or a form of haze.

Berta said that if the predictions of GJ 1214b were proved correct, the planet had more water than the globe and its internal structure was also different from ours. Extremely high temperatures and extreme pressures on it can lead to the formation of unprecedented human forms such as hot ice and super liquid water. GJ 1214b may be a representative of a completely new type of planet for humans.

Since GJ 1214b is only 40 light-years away from Earth, it will become the ideal observation object of the James Webb space telescope after the glasses are launched in the next few years to replace the Hubble telescope.

The existence of liquid water and moderate surface temperatures are two of the necessary conditions for life to form and grow on planets.
