In theory, it could happen – one of the very first solutions to the three-body problem was this scenario. But it is very unlikely to be stable over time. You need the stars to have near equal mass and ...

What happens when a planet defies every expectation of how worlds are supposed to form and move? In the nu Octantis system, astronomers have confirmed the existence of a planet that orbits in 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 ...

Astronomers have confirmed a giant planet orbiting a tightly bound pair of young stars, marking a first in direct exoplanet imaging. The planet, known as HD 143811 AB b, is the closest-in world ever ...

Is it a two-for-sun deal. Astronomers were blown away after discovering a bizarre exoplanet that orbits twin stars closer than any ever seen before in a binary star system, per a starry study ...

In 2018, astronomers discovered a pair of brown dwarf stars orbiting each other in a rare system known as an eclipsing binary. Further observations show that the binary, named 2M1510, is even more ...

Apples-to-apples comparisons in the distant universe are hard to come by. Whether the subject is dwarf galaxies, supermassive black holes, or 'hot Jupiters,' astronomers can spend months or years ...

Three physicists have proposed a technique for detecting pairs of supermassive black holes that have so far eluded every ...
