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, ...

Researchers have theorized that our Sun once had a binary companion or another star that was roughly the same size as itself. The binary pair may have been responsible for drawing in the wealth of ...

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 ...

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 ...

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 ...

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 ...

Monisha Ravisetti was a science writer at CNET. She covered climate change, space rockets, mathematical puzzles, dinosaur bones, black holes, supernovas, and sometimes, the drama of philosophical ...

While the Sun is very clearly a solo act nowadays, some astronomers theorize that it once had a binary companion star. Now, Harvard scientists have added weight to the idea by showing that an ancient ...

Astronomers using the VLBA have produced a full, 3-D view of a binary star system with a planet orbiting one of the stars. Their achievement promises important new insights into the process of planet ...

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 ...
