A bizarre planet defies cosmic norms: scientists have confirmed a giant planet orbiting in reverse around one star in a close ...

Exoplanets in binary star systems usually orbit both stars, but astronomers have now spotted three planets orbiting one or the other star in a pair By Alex Wilkins 19 September 2024 ...

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 ...

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 ...

An international team of scientists have provided an unprecedented tally of elemental sulfur spread between the stars using ...

For the first time, a team of astronomers have observed a binary star system that is destined to end in a type 1a supernova in this new study. The stars’ close proximity to us is an added bonus.

The binary star system sits roughly 150 light-years from Earth. It's also incredibly heavy, with a combined mass equal to about 1.56 times that of the sun.

Located 26,000 light-years away from Earth, the neutron star is part of an x-ray binary star system called 4U 1820-30.

We’ll see how T CrB behaves.” It is important to note, because of the distance between the Earth and this star system, that we’re actually seeing an explosion that occurred 3,000 years ago.

The binary star system discovered in the new study is the heaviest of its kind that's ever been confirmed, with a combined mass that's 1.56 times that of the sun.

Using computer models, the researchers suggest the members of this newfound binary started at a distance from each other about twice that between Earth and the sun (185 million miles, or 299 ...
