What"s the link between gamma ray bursts and supernovae? It might be binary stars
Gamma-ray bursts (GRBs) are some of the most violent events in the universe. Some have a power output equivalent to all of the other stars in the observable universe, at least in the spectrum of gamma rays. But we know very little about them. A new p.....»»
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.....»»
Hubble zooms into the rosy tendrils of Andromeda
Clusters of stars set the interstellar medium ablaze in the Andromeda galaxy about 2.5 million light-years away. Also known as M31, Andromeda is the Milky Way's closest major galaxy. It measures approximately 152,000 light-years across and, with almo.....»»
Observatory reveals key evidence of cosmic ray acceleration limit in W51 for first time
The Large High Altitude Air Shower Observatory (LHAASO) officially released the precise measurements of high-energy gamma radiation from the W51 complex, confirming it as a cosmic-ray accelerator boosting particles up to so-called ultra-high energies.....»»
Hubble observes an oddly organized satellite galaxy
Andromeda III is one of at least 13 dwarf satellite galaxies in orbit around the Andromeda galaxy, or Messier 31, the Milky Way's closest grand spiral galactic neighbor. Andromeda III is a faint, spheroidal collection of old, reddish stars that appea.....»»
New model to enhance extreme rainfall prediction
New research by an international team of climate experts shows intense, localized, heavy bursts of rainfall can be caused by a rapid rise of air through clouds and proves that these rises in air can be forecast. The team has developed a unique, cutti.....»»
Is Betelgeuse actually a binary star?
Betelgeuse has been a favorite among amateur astronomers for many years. However you pronounce it, its unexpected dimming draws even more attention to this red supergiant variable star in Orion. It has a few cycles of variability. One of them occurs.....»»
Hubble traces star formation in nearby nebula NGC 261
NGC 261 blooms a brilliant ruby red against a myriad of stars in this new image from NASA's Hubble Space Telescope. Discovered on Sept. 5, 1826 by Scottish astronomer James Dunlop, this nebula is located in one of the Milky Way's closest galactic com.....»»

Novel features of r-process nucleosynthesis shed light on origin of heavy elements
In a study published in The Astrophysical Journal, scientists have proposed the features of the rapid neutron capture process (r-process) nucleosynthesis in a novel scenario: common envelop jet supernovae (CEJSNe). The study sheds new light on the or.....»»
