Astronomers may have identified a rare binary star system where one star orbits within the volume of its companion. This discovery opens a new window into the evolution of double star systems. The ...

In theory, a planet may be able to orbit a binary star system in a figure of eight, but it may not be particularly stable, ...

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 ...

Apples-to-apples comparisons in the distant universe are hard to come by. Whether the subject is dwarf galaxies, supermassive black holes, or “hot Jupiters,” astronomers can spend months or years ...

A recent study published in The Astrophysical Journal Letters explores how binary star systems—two stars born together orbiting each other—can serve as natural laboratories for understanding planet ...

In 2018, astronomers discovered a pair of brown dwarf stars orbiting each other in a rare system known as an eclipsing binary. Further observations show that the binary, named 2M1510, is even more ...

From above a planet about twice the size of Jupiter, this artist's conception shows the star that planet is orbiting and that star's binary companion in the distance. CREDIT Sophia Dagnello, ...

A team of astronomers have used the United Kingdom Infrared Telescope (UKIRT) on Hawaii to discover four pairs of stars that orbit each other in less than 4 hours. Until now it was thought that such ...

An international team of researchers led by PD Dr Florian Peißker has found the first binary star in the immediate vicinity of the supermassive black hole Sgr A* (Sagittarius A star) at the centre of ...
