While no scientist has stated to believe GJ 1214 b is an ocean planet, if GJ 1214 b is assumed to be an ocean planet, [22] i.e. the interior is assumed to be composed primarily of a water core surrounded by more water, proportions of the total mass consistent with the mass and radius are about 25% rock and 75% water, covered by a thick envelope ...
An alternative possibility is that 55 Cancri e is a solid planet made of carbon-rich material rather than the oxygen-rich material that makes up the terrestrial planets in the Solar System. [25] In this case, roughly a third of the planet's mass would be carbon, much of which may be in the form of diamond as a result of the temperatures and ...
Diamonds so small that they contain only about 2000 carbon atoms are abundant in meteorites, and some of them formed in stars before the Solar System existed. [1] High pressure experiments suggest large amounts of diamonds are formed from methane on the ice giant planets Uranus and Neptune , while some planets in other planetary systems may be ...

Gliese 581g / ˈ ɡ l iː z ə / was a candidate exoplanet postulated to orbit within the Gliese 581 system, twenty light-years from Earth. [9] It was discovered by the Lick–Carnegie Exoplanet Survey, and was the sixth planet claimed to orbit the star; [10] however, its existence could not be confirmed by the European Southern Observatory (ESO) / High Accuracy Radial Velocity Planet Searcher ...
Scientists have found a new Earth-like planet that could support alien life – just 40 light-years away.. The planet is a remarkable discovery in the search for habitable worlds: it is slightly ...
Before now, researchers had not been able to map how water is distributed in a stable, cool disc. Astronomers find new link between water and planet formation Skip to main content
The team released a paper of their findings dated 27 April 2007, published in the July 2007 journal Astronomy & Astrophysics. [1] At the time of discovery, it was reported to be the first potentially Earth-like planet in the habitable zone of its star [5] [6] and the smallest-known exoplanet around a main-sequence star, but on 21 April 2009, another planet orbiting Gliese 581, Gliese 581e ...
