Astronomers have captured a rare and remarkably close view of a giant planet circling a pair of tightly bound suns, offering one of the clearest real-world echoes yet of the fictional world Tatooine.

Binary star systems have always captured people’s imagination, but this video looks at them as real places humanity might one ...

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 ...

An international team of astronomers reports the discovery of a new pre-main-sequence eclipsing binary system. The newfound binary, designated MML 48, consists of two young low-mass stars. The finding ...

Astronomers have found thousands of exoplanets around single stars, but few around binary stars—even though both types of stars are equally common. Physicists can now explain the dearth. Of the more ...

A star you can see with the naked eye has kept astronomers guessing for decades with its unusually powerful X-rays. Now, ...

Some stars in our galaxy, known as hypervelocity stars, move much faster than most other stars in the Milky Way. In fact, they are traveling so fast that our galaxy’s gravity can’t hold onto them and ...

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 ...
