A first ever detection of a coronal mass ejection from a small red dwarf could have big consequences for life on any nearby ...

A pattern in the movements of a brown dwarf that orbits a Sun-like star is likely to be caused by a moon. If confirmed, this would be the first exomoon, that is a moon orbiting a planet that in turn ...

Some white dwarfs in rapid binary orbits are far hotter and larger than theory predicts. Researchers found that powerful tidal forces between them generate enough heat to inflate their sizes and ...

It's impossible to tell for sure how many stars there are in the Universe for the simplest reason that it's impossible to see them all, let alone count them. Some estimates, based on, well, more or ...

Astronomers recently peered deep into space and found that an old, faint white dwarf named LSPM J0207+3331, located about 145 light-years away, is still consuming the rocky remains of its former ...

An international team of astronomers has discovered the coldest brown dwarf star ever observed. This finding is a new step toward filling the gap between stars and planets. An international team [1] ...

An international team of astronomers led by Dr Iris de Ruiter, now at the University of Sydney, has shown that a white dwarf and a red dwarf star orbiting each other every two hours are emitting radio ...

New research has shed doubt upon the nature of a distant "dead star" that exists in a binary system with an active stellar companion. Scientists behind the research think this stellar corpse is ...

The event occurred at the edge of the Milky Way. — -- Astronomers have uncovered evidence that a white dwarf may have gone into death star mode on the edge of the Milky Way, shredding a planet ...
