Star pairs are typically very similar, but in HD 148937, one star appears younger and is magnetic. New data from the European Southern Observatory (ESO) suggest there were originally three stars in the system, until two of them clashed and merged.
A record-breaking binary system has been found with a rotation so tight, both objects could comfortably fit inside the Sun.
Astronomers studying data from NASA’s TESS mission have found a remarkable sextuple star system featuring three gravitationally bound eclipsing binaries.
A mysteriously dimming star located about 1,480 light-years away in the constellation of Cygnus and known as Tabby's star is, in fact, a binary stellar system, made up of a F-type star and a smaller red dwarf star.
Astronomers have found six objects orbiting Sagittarius A* that are unlike anything in the galaxy. These objects look like gas but behave like stars. They are so peculiar that they have been assigned a brand-new class - what astronomers are calling G objects.
Recent research suggests that most, if not all, stars are born with a binary twin. Our Sun is a solitary star, but there's evidence to suggest that it did have a binary twin, once upon a time and it might have just been found.
