A planetary system 116 light-years from Earth has a peculiar pattern. It could flip the script on how planets form, scientists say.
Their observations of a faint, cool M-dwarf star called LHS 1903 revealed a system with a rocky world at its outer edge. LHS ...
NASA’s Transiting Exoplanet Survey Satellite (TESS) has been used to discover Earth-size planet TOI 700 e. It is "orbiting ...
A rocky exoplanet in the LHS 1903 system defies planet formation models, hinting that gravitational upheaval reshaped the red ...
General relativity helps explain the lack of planets around tight binary stars by driving orbital resonances that eject or destroy close-in worlds. This process naturally creates a “desert” of ...
12 years of W.M. Keck Observatory imagery of star system HR 8799 have been time-lapsed. The system hosts four planets that ...
The Necklace Nebula (PN G054.2-03.4) formed when one star in a close binary system expanded into a red giant and engulfed its ...
A newly identified planet candidate, HD 137010 b, looks strikingly Earth-like in size and orbit — but it may be colder than Mars due to its dimmer star. If it has a thick enough atmosphere, though, ...
If a gas giant planet is big enough to ignite deuterium fusion, it becomes a brown dwarf instead of a planet. But this definition is incomplete and does not tell us how gas giants form or what ...
New observations from NASA's James Webb Space Telescope (JWST) suggest that even extremely massive gas giants — once thought ...
The candidate is coined HD 137010 b. It would orbit a K-type dwarf star approximately 146 light-years from Earth. The evidence comes from a single transit pattern seen in K2 data from 2017: the star ...
