Gaia BH1 has a mass of 9.62 times the mass of the Sun and is orbited by a bright Sun-like star at about the same distance as our planet orbits the Sun....
Using data from NASA’s Chandra X-ray Observatory and ESA’s XMM-Newton spacecraft, astronomers have looked for the effects of massive, close-in planets...
The newly-discovered black hole resides in the binary system Gaia DR3 4373465352415301632 with a main-sequence star that is slightly smaller than the Sun....
An image of the binary system WR 140, captured by the NASA/ESA/CSA James Webb Space Telescope in July 2022, has baffled astronomers worldwide — even...
ZTF J1813+4251 is a 51-minute-orbital-period, fully eclipsing binary system consisting of a star with a temperature comparable to that of the Sun but...
Earendel is a B-type giant star, a luminous blue variable star, or even a binary system with an extremely hot primary member, according to new observations...
Astronomers using NASA’s Transiting Exoplanet Survey Satellite (TESS) and the SPIRou spectropolarimeter on the 3.6-m Canada-France-Hawaii telescope have...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have for the first time detected the millimeter afterglow of a short-duration...
PSR J0952-0607, a so-called millisecond pulsar, has shredded and consumed nearly the entire mass of its stellar companion and, in the process, grown into...
Zeta Ophiuchi is a very massive, hot, bright blue star that once had a companion that exploded as a supernova.
Zeta Ophiuchi was once in close orbit with...
TIC 470710327, a massive, compact hierarchical triple-star system recently identified by NASA’s Transiting Exoplanet Survey Satellite (TESS), was originally...
The newly-detected black hole is a member of the binary system VFTS 243, which is located in the famous Tarantula Nebula in the Large Magellanic Cloud.
This...
Using data from the NOIRLab Source Catalog (NSC) DR2, citizen scientist Frank Kiwy has discovered 34 new M-, L-, or T-type dwarfs comoving with low-mass...
There are different types of supernova explosions. Type Ia supernovae, also known as thermonuclear supernovae, occur in binary star systems. To trigger...
Gaia’s data release 3 (DR3) contains new and improved details for almost 2 billion stars in our Milky Way Galaxy as well as for a subset of solar system...
