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 ...

Surprised astronomers said Thursday they have discovered a star with planets in a bizarre order that defies scientific expectations – and suggests these faraway worlds formed in a manner never seen ...

Key takeawaysIf a gas giant planet is big enough to ignite deuterium fusion, it becomes a brown dwarf instead of a planet.

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, ...

Their observations of a faint, cool M-dwarf star called LHS 1903 revealed a system with a rocky world at its outer edge. LHS 1903 is an ancient star, around seven billion years old, and only has about ...

A closer look at the planets around a star called LHS 1903 may just flip our understanding of how planetary systems form.

The similarities are astonishing. And yet... The post NASA Telescope Discovers Nearby Planet With Deep Similarities to Earth ...
