PSR J1719−1438 b is an extrasolar planet that was discovered on August 25, 2011, in orbit around PSR J1719−1438, a millisecond pulsar. The pulsar planet is most likely composed largely of crystalline carbon but with a density far greater than diamond. [1] [2] PSR J1719-1438 b orbits so closely to its host star that its orbit would fit ...
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 ...
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 almost pure diamond. [2] Diamonds are also found in stars and may have been the first mineral ever to have formed.
Scientists say they have found new evidence that there is a hidden planet in our solar system. For years, some astronomers have been suggesting that unusual behaviour on the edge of our solar ...
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 ...
The Summary. A NASA spacecraft brought samples from the asteroid Bennu back to Earth in 2023. The first in-depth analyses of that material have revealed organic molecules, including building ...

Wolf Cukier, a 17-year-old attending Scarsdale High School in New York at the time, joined the Goddard Space Flight Center in 2019 to work as a summer intern. While studying data that was flagged as an eclipsing binary (provided by volunteers of the Planet Hunters citizen science project), he found the planet on his third day of interning.
