Are Sun-like stars the only stars where Earth-like worlds exist? This is what a recent study presented this morning at the ...

Technically, the sun is a G-type main-sequence star — specifically, a G2V star. The "V" indicates that it is a dwarf, Tony Wong, a professor of astronomy at the University of Illinois Urbana-Champaign ...

Although astronomers often refer to brown dwarfs as "failed stars," scientists at the University of Delaware have discovered that at least one of these dim celestial objects can emit powerful flashes ...

At a time when astronomers are peering into the most distant Universe, looking at objects as far as 13 billion light-years away, one may think that our close neighbourhood would be very well known.

Computer simulations suggest that if a more massive object, like a brown dwarf (which contains the mass of dozens of Jupiters), orbited the Sun instead of Jupiter, it would have been harder for Earth ...

Using a telescope specifically designed to hunt for exoplanets, a team of astronomers working at the European Southern Observatory (ESO) has discovered three planets orbiting a dwarf sun just 40 light ...

A fiery nova explosion from a white dwarf star that made it at least 60 times hotter than the sun has been observed by scientists who termed the sighting a “fortunate coincidence”. When stars like the ...

A newly discovered binary system, 1400 light-years away, comprises a brown dwarf orbiting a white dwarf (WD 0032-317). The brown dwarf's extreme temperature (approximately 7,700°C) is primarily due to ...

A brown dwarf as cold as the North Pole has been discovered lurking remarkably close to our solar system, and it appears to be the coldest of its kind yet found, scientists say. Using NASA's ...

Astronomers are looking for the bones of dead planets inside the corpses of dead stars — and they may have just found some. In a paper published Feb. 11 in the journal Nature Astronomy, a team of ...
