Although diamonds on Earth are rare, extraterrestrial diamonds (diamonds formed outside of Earth) are very common. 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 ]
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 ...
The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
“We have discovered that next step on a pathway to life.” This mosaic image of asteroid Bennu, was taken on December 2, 2018 by the OSIRIS-REx spacecraft from a range of 15 miles.

By RYAN GORMAN Scientists may have found Planet X -- the long-rumored object believed to be larger than Earth and further from the sun than Pluto. Planet X and another object dubbed "Planet Y ...
The two new studies represent the first in-depth analyses of the Bennu samples. In 2023, scientists announced preliminary findings, including traces of carbon and water locked up in clay minerals .
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 ...
