Scientists have discovered a new class of extrasolar planets -

American astronomers have studied the imagery of the orbital observatory, Hubble, and on that basis have identified a new class of exoplanets - worlds of water with a dense and thick atmosphere, whose size and mass of the earth more, but less than that of Uranus.

At present, the two most common types of extrasolar planets are so-called ... RIA Novosti. ... ...
A team of astronomers led by Bert graves of the Harvard- Smithsonian Center for Astrophysics in Cambridge, announced the existence of another class of extrasolar planets by examining the first of the alleged ...
This is a celestial body was discovered earlier planetologists group led by David Charbonneau of the Harvard- Smithsonian Center for Astrophysics in 2009. The planet orbits a red dwarf star GJ 1214, in the constellation Ophiuchus, remote from us at a distance of 40 light years away.
Discoverers GJ 1214b ranked it among the ... Most astronomers assume that these characteristics GJ 1214b can be explained by the fact that it is a water world - a planet with a small hard core and a giant ocean around it.
Scientists have observed the change in the emission spectrum of a dwarf star at a time until the planet passed in its drive. How to explain astrophysics, rays of light ... Because of this, the emission spectrum of the star there are new lines that indicate the presence of certain substances in the atmosphere of the planet.
Hubble images show that the atmosphere of GJ 1214b is a dense steam with the addition of small amounts of helium and hydrogen. Given the extremely high temperature at the surface of the planet - about 200 degrees Celsius - the water in the oceans, it should be in an exotic state.

To date, scientists have discovered several more planets similar in its characteristics to the GJ 1214b. It is possible that these celestial bodies are quite common in the Universe.
