Did this supernova explode twice?
All supernovae are exploding stars. But the nature of a supernova explosion varies quite a bit. One type, named Type 1a supernovae, involves a binary star where one of the pair is a white dwarf. And while supernovae of all types usually involve a sin.....»»

Double-peaked supernovae offer clues to pre-supernova outbursts
New research helps in understanding the evolution and final stages of massive stars, the role of binary interactions, and the mechanisms behind mass loss, which ultimately affect the properties of the resulting supernova and its remnant. This work al.....»»
Observations investigate the connection of a supernova remnant with a nearby H II region
Chinese astronomers have performed multi-wavelength observations of a galactic supernova remnant known as HB9. Results of the observational campaign, published August 9 on the preprint server arXiv, shed more light on the remnant's properties and its.....»»
Neutron-star mergers illuminate the mysteries of quark matter
Neutron stars are the remnants of old stars that have run out of nuclear fuel and undergone a supernova explosion and a subsequent gravitational collapse. Although their collisions—or binary mergers—are rare, when they do occur, these violent eve.....»»
Hubble spotlights a supernova
This NASA/ESA Hubble Space Telescope image features the galaxy LEDA 857074, located in the constellation Eridanus. LEDA 857074 is a barred spiral galaxy, with partially broken spiral arms. The image also captured a supernova, named SN 2022ADQZ, shini.....»»
Image: Doomed star Eta Carinae
Eta Carinae may be about to explode. But no one knows when—it may be next year, it may be 1 million years from now. Eta Carinae's mass—about 100 times greater than our sun—makes it an excellent candidate for a full blown supernova......»»
Ever see a star explode? You"re about to chance very soon
Every clear night for the last three weeks, Bob Stephens has pointed his home telescope at the same two stars in hopes of witnessing one of the most violent events in the universe—a nova explosion a hundred thousand times brighter than the sun......»»
Webb unveils stunning ejecta and CO structures in Cassiopeia A"s young supernova
The SETI Institute announced the latest findings from the James Webb Space Telescope (JWST) of the supernova remnant, Cassiopeia A (Cas A). These observations of the youngest known core collapse supernova in the Milky Way provide insights into the co.....»»
Hubble measures the distance to a supernova
Measuring the distance to truly remote objects like galaxies, quasars, and galaxy clusters is a crucial task in astrophysics, particularly when it comes to studying the early universe, but it's a difficult one to complete......»»
BMW recalls nearly 400,000 U.S. vehicles for faulty airbags; NHTSA warns on using replacements
BMW of North America is recalling about 394,029 vehicles in the U.S. over concerns that airbags might explode during deployment. NHTSA also warned consumers about using replacement airbags......»»
Elusive temporary star described in historical documents recreated using new computer model
A mysterious remnant from a rare type of supernova recorded in 1181 has been explained for the first time. Two white dwarf stars collided, creating a temporary "guest star," now labeled supernova (SN) 1181, which was recorded in historical documents.....»»
