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.

A long-standing astronomical mystery about the first-ever discovered brown dwarf has finally been solved by scientists. The brown dwarf, named Gliese 229B, was discovered in 1995 but has puzzled ...

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 ...

Stars usually form in clusters, which can also form in pairs or groups. Binary clusters (BCs) are defined as pairs of open ...

collaborators Elizabeth Waltman of the Naval Research Laboratory, and Frank Ghigo of the National Radio Astronomy Observatory (NRAO). "This long-term survey was critical to our understanding of the ...

Radio astronomers have been puzzled over the past few years by super-bright radio waves dubbed long-period radio transients. These signals appear to come from various locations around our galaxy, but ...

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 ...

Almost 25,000 light-years away, two dead stars, each more massive than our Sun, but only 20 kilometers in diameter, orbit one another in less than five hours. This unusual pair of extreme objects, ...

"Black holes are not as destructive as we thought. It seems plausible that the detection of planets in the galactic center is just a matter of time." When you purchase through links on our site, we ...

This artist's impression shows how hot, brilliant and high-mass stars evolve. The more massive brighter star expands first, until the outer layers start to strongly feel the gravitational pull of the ...

Astronomers have discovered the first pairs of white dwarf and main sequence stars -- 'dead' remnants and 'living' stars -- in young star clusters. This breakthrough offers new insights on an extreme ...
