Binary asteroid systems are widespread throughout our inner solar system. For decades, the standard paradigm held that many ...

Astronomers have investigated a puzzling binary star system in which two stars that may have formed together now show ...

New simulations show that interactions with a magnetic field can work to decrease the distance between still forming binary ...

Scientists have uncovered a surprising force that may help explain how binary star systems form so quickly. New supercomputer ...

Magnetic fields may be the hidden force bringing both newborn stars and giant black holes together. New computer simulations ...

A triple star system in which the stars all eclipse one another from our vantage point is standing out as one of the best ...

M33 X-7 contains a massive black hole orbiting a large star in a surprisingly close orbit. The star is dimmer than expected due to its rapid mass gain and viewing angle. A new model explains the ...

For the first time, astronomers have spotted a rapidly spinning neutron star that is gravitationally bound to a helium star companion. The discovery of this unusual binary system helps confirm a long ...

In the last two years, astronomers discovered several exoplanets in binary systems: two stars locked in mutual orbit. These systems come in several types, with the planet orbiting one or both stars.
