As much as 45 oceans’ worth of hydrogen may be in Earth’s core, scientists reported, suggesting most of Earth’s water was ...

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, ...

Alexander Venner picked his way by hand through the data collected by a now-retired NASA telescope called Kepler, which ...

Astronomers have uncovered a distant planetary system that flips a long-standing rule of planet formation on its head. Around the small red dwarf star LHS 1903, scientists expected to find rocky ...

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 ...

SIGNS of an alien planet that’s about the same size as Earth have been picked by up a Nasa telescope. Scientists say it might ...
