A pair of white dwarfs race around each other every 374 seconds, creating a rhythmic X-ray beacon that could reveal powerful gravitational waves. Every 6.2 minutes, two dead stars...
Astronomers used 8 years of observations to create a 3D image of a very young, very massive binary star as it forms. The image shows that the disks in the system are all misaligned...
Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have captured one of the most detailed three-dimensional views yet of a massive binary star system while...

Astronomers detected an unusual triangular light curve about 300 light years away. They were searching for Black Widow Binaries, where a dense neutron star eats its companion. But...
Future gravitational wave observatories will be able to see the gravitational waves of close-orbiting binary stars. A newly studied white dwarf system could be one of the first sys...
Like Earth, most planetary bodies circle their star in stable, detached orbits. These companionable systems can suddenly change when a planet comes too close to its star. In such a...
Astronomers have found a four-star system doing something that has never been confirmed before. The system, TIC 433545934, has two close pairs of stars orbiting each other. While e...
Astronomers have discovered a star slowly eating its companion in an extraordinary cosmic feast that could last billions of years. A small star about 300 light-years from Earth is...
Most stars, including massive ones, are in binary pairs. Astronomers think that about 70% of them have gained mass from their companions, but there's been no way to determine which...
While astronomers have found thousands of exoplanets over the last few decades, the true prize continues to elude them - they have yet to find an Earth-mass, rocky planet orbiting...
The newfound star S301 orbits the Milky Way’s supermassive black hole so closely that its view of the heavens gets twisted
Discover how an anomaly that has puzzled astronomers for years was solved, and what it can tell us about how stellar systems interact.
While astronomers have found thousands of exoplanets over the last few decades, the true prize continues to elude them—they have yet to find an Earth-mass, rocky planet orbiting...
Gaia has discovered three stellar mass black holes, each with a small stellar companion. For two of these systems the companions orbit closer that we would expect. Just how these s...
The discovery reveals a new way that stars and planetary companions can interact.
Red and white dwarf stars may be hungrier than we thought
New research led by the University of Michigan is helping set the stage for future observatories to characterize rocky planets outside our solar system, planets that could prove li...
Using data from the Japan–led XRISM (X-ray Imaging and Spectroscopy Mission) observatory, astronomers have directly observed a giant star's outflow, called a stellar wind, being ca...
A star and its planets form when a cloud of gas and dust collapses in on itself somewhere in space. The cloud then forms a disk around the nascent star, within which the planets wi...
30 years ago, an amateur astronomer noticed a white dwarf star suddenly getting brighter. New research shows this is due to a Very Late Thermal Pulse, a type of helium flash. The s...
A group of astronomers proposes that a series of events in a distant galaxy formed both a black hole and a pulsar, but other experts say the conclusion is premature
For the first time since its dramatic dimming in 2020, a team of astronomers has observed the inner atmosphere of Betelgeuse using the Atacama Large Millimeter Array (ALMA). Led by...
Astrophysicists at Syracuse University in New York think they've found a hitherto-hidden explanation for strange activity during so-called repeating partial Tidal Disruption Events...
