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.

Last October, astronomers spotted the first known visitor from another star system as it zoomed through the inner solar system at breakneck speeds. The interstellar interloper, since named ‘Oumuamua ...

New research finds that ‘Oumuamua, the rocky object identified as the first confirmed interstellar asteroid, very likely came from a binary star system. “It’s remarkable that we’ve now seen for the ...

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 ...

In a recent study accepted to Astronomy & Astrophysics, a team of researchers use a combination of space- and ground-based telescopes to examine a binary star system (two stars orbiting each other) in ...

Washington DC — New theoretical work shows that gas-giant planet formation can occur around binary stars in much the same way that it occurs around single stars like the Sun. The work is presented ...

Tatooine lovers, rejoice! Another planet orbiting a binary star system has been discovered, which can only up the odds of eventually finding an IRL sandy world resembling the one in Star Wars. On top ...

Stars are the fundamental building blocks of our universe. Most stars host planets, like our sun hosts our solar system, and if you look more broadly, groups of stars make up huge structures such as ...
