Not so fast, supernova: Highest-energy cosmic rays detected in star clusters
For decades, researchers assumed the cosmic rays that regularly bombard Earth from the far reaches of the galaxy are born when stars go supernova—when they grow too massive to support the fusion occurring at their cores and explode......»»
Indonesia"s Sinabung volcano unleashes new burst of hot ash
A rumbling volcano on Indonesia's Sumatra island unleashed an avalanche of searing gas clouds flowing down its slopes during eruption on Thursday. No casualties were reported......»»

Hoinga: Debris of stellar explosion found in unexpected location
In the first all-sky survey by the eROSITA X-ray telescope onboard SRG, astronomers at the Max Planck Institute for Extraterrestrial Physics have identified a previously unknown supernova remnant, dubbed "Hoinga." The finding was confirmed in archiva.....»»
Extinct atom reveals the long-kept secrets of the solar system
Using the extinct niobium-92 atom, ETH researchers have been able to date events in the early solar system with greater precision than before. The study concludes that supernova explosions must have taken place in the birth environment of our sun......»»
Chemical signatures of iron predict red supergiant temperature
Red supergiants are a class of star that end their lives in supernova explosions. Their lifecycles are not fully understood, partly due to difficulties in measuring their temperatures. For the first time, astronomers have developed an accurate method.....»»
