D9 is the first star pair ever found near Sagittarius A*, the supermassive black hole at the centre of the Milky Way. This image shows an emission line of hydrogen mapped by the SINFONI instrument ...

Binary star systems, or pairs of stars that orbit around each other, are very common. In fact, it’s estimated that 85% of stars in the universe have at least one companion.

HFG1 features a prominent bluish arc-shaped shock wave, known as a bow shock, created as the binary star system V664 Cas speeds through our Milky Way galaxy. Bow shocks are crescent-shaped ...

This illustration depicts a binary star system consisting of a dense neutron star and a normal Sun-like star (upper left). Using data from the European Space Agency's Gaia mission, astronomers ...

Astronomers have identified a rare type of binary star system containing a rapidly spinning millisecond pulsar and a helium star companion, formed via common envelope evolution. Although such ...

One of them has yielded the first compelling evidence of a binary star system — called D9 — orbiting the galactic center. This pair of stars orbit each other about once a year.

Astronomers may have discovered a rare type of binary star system, where one star used to orbit inside its partner. In the new study, astronomers investigated a pulsar known as PSR J1928+1815 ...

Binary star system detected near Sagittarius A*. Binary stars often appear as a single object in the night sky to the naked eye, but can often be detected with telescopes and the data they provide.

The binary star system T Coronae Borealis (T CrB), also known as the Blaze Star, periodically explodes every 79 years or so, competing with the brightest stars in the night sky.A paper published ...

T Coronae Borealis, also known as the "Blaze Star," is expected to explode violently in the near future, illuminating a long-dead binary star system for the first time in 80 years, according to NASA.

Astronomers may have discovered a rare type of binary star system, where one star used to orbit inside its partner. In the new study, astronomers investigated a pulsar known as PSR J1928+1815 ...
