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 ...

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 ...

A research team has used both archival Hubble Space Telescope data and new observations to precisely measure the binary star system NGC3603-A1. One star weighs about 93 times the mass of our sun, ...

Astronomers have made a groundbreaking discovery of three Earth-sized planets orbiting within a compact binary star system. This rare configuration, where planets circle two stars simultaneously, ...

How many Earth-sized exoplanets orbit binary star systems (two-star systems)? This is what a recent study accepted by Astronomy & Astrophysics hopes to address as an international team of researchers ...

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 ...

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 ...
