An international research team announces the discovery of a new exoplanet orbiting a binary star system. Named HD 143811 b, ...

Since the third Gaia data release in 2022, wide binary stars with separation greater than several thousand astronomical units have been intensely investigated across the world, to probe the nature of ...

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.

Especially with the discovery of Pluto’s fifth moon in 2012, the distant icy planet and its largest moon Charon has gotten a lot of attention. You’ve undoubtedly heard Pluto referred to as the ...

Astronomers have developed the most realistic model to date of planet formation in binary star systems. The researchers, from the University of Cambridge and the Max Planck Institute for ...

Astronomers have long debated why so many icy objects in the outer solar system look like snowmen. Michigan State University ...

While astronomers studied the asteroid belt in between Mars and Jupiter with the Hubble Space Telescope over the course of several years, they came across a rather peculiar finding in a binary ...

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 ...

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 ...

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 ...

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 ...
