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.....»»
Pre-pilot survey explores dozens of candidate ultra-diffuse galaxies
By analyzing the data from the WALLABY pre-pilot survey, astronomers from the University of Western Australia and elsewhere, have inspected 78 candidate ultra-diffuse galaxies in the Eridanus supergroup. The study was detailed in a paper published Se.....»»
Modeling shows fires from volcanic activity could greatly increase area affected by eruption
An international research team, including researchers from GNS Science, has released a study into the potential threat of fires caused by volcanic eruptions. The study investigated how far fires ignited by hot rock projectiles from a volcanic eruptio.....»»
NASA"s Chandra rewinds story of great eruption of the 1840s
