In 2004, an astronomer at the University of Canterbury, in New Zealand, observed something odd in the v Octantis binary star system—a repeating signal between the two stars that made up the system.

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 ...

Astronomers have strengthened long-standing predictions that massive runaway stars could have originated in binary pairs, and ...

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 ...

Ferris State University student researcher Francisco Vasquez worked with his professor, Dr. Dinesh Shetty, to create new orbital models for binary star systems, four of which have been adopted by the ...

Citizen scientists have successfully located thousands of previously unknown pairs of “eclipsing binary” stars, NASA announced in June. The ongoing initiative helps space researchers hunt for ...

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 recently released a new image of the binary star system Eta Carinae's full spectrum, taken from deep in Chile's Atacama Desert. The image was captured with the newly installed SOAR ...

Although Joe Smith has always been curious and interested in many things, his desire to learn more led him to join a nonprofit astronomy group when he was a high school freshman. His curiosity about ...

Why is it so rare to find exoplanets orbiting two stars, also called circumbinary planets (CBPs)? This is what a recent study ...

Scientists have long speculated about the possibility of our Sun having a twin star, a theory that has gained traction with recent data. The evidence and implications of a potential solar sibling shed ...

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 ...
