This graphic shows the relative size of the Sun, upper left, compared to the two stars in the binary system known as Wolf-Rayet 140, or WR 140. The O-type star is roughly 30 times the mass of the Sun, ...

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

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 ...

This unusual system 'shouldn't exist,' says one astronomer, who notes the orbit is as long as his daily commute. By Briley Lewis Published Aug 8, 2023 6:00 AM EDT Get the Popular Science daily ...

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 ...

General relativity helps explain the lack of planets around tight binary stars by driving orbital resonances that eject or destroy close-in worlds. This process naturally creates a “desert” of ...

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 ...

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 ...

Astronomers have observed primordial material that may be giving birth to three planetary systems around a binary star in unprecedented detail. Astronomers have observed primordial material that may ...

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 ...
