Is there anything more awesome in space than black holes, the phantasmal, jet-spewing regions of spacetime that are so densely packed with matter that they collapse under their own gravity Actually, yes: Some of these black hole jets seem to cause stars to explode. These stars are not in the direct paths of the jets, but close enough to the near-light-speed particle beams that it causes them to erupt. The stars in question are white dwarfs鈥攂urnt-out shells of stars that take on hydrogen from their companion star. Once the dwarfs have about a mile-thick

We don ;t know what going on, but it just a very exciting finding, said Alec Lessing, an astrophysicist at Stanford University and lead author of a new study describing the phenomenon, in an ESA release. In the recent work鈥攕et to publish in The Astrophysical Journal and is currently hosted on the preprint server arXiv鈥攖he team studied 135 novae in the galaxy M87, which hosts a supermassive black hole of the same name at its core. M87 is 6.5 billion times the mass of the Sun and was the first black hole to be directly imaged, in work done in 2019 by the Event Horizon Telescope Collaboration. The team found twice as many novae erupting near M87 3,000 light-year-long plasma jet than elsewhere in the galaxy. The Hubble Space Telescope also directly imaged M87 jet, which you can see belo Eydt Britney Spears Is a Big Fan of Gus Kenworthy and Adam Rippon. The Feeling Is Mutual
By Amanda MacMillan / RealSimpleJune 26, 2017 3:35 PM EDTThe next time a friend calls you and asks for a favor, how willing you are to lend a hand may have a lot to do with one unexpected factor: the heat. According to a new study in the European Journal of Social Psychology, uncomfortably hot environments make people less likely to help others in need.Past research has demonstratedmdash;and you may certainly agreemdash;that a really hot day can induce feelings of grumpiness and even hostility toward everyone around you. But this is the first study to show a link between ambient temperature and prosocial behaviors, which are essentially those selfless deeds that benefit other people, organizations, or society as a whole, but not explicitly ourselves.To study this connection, researchers from Lehigh University and Northwestern University performed three experiments. In the first, they found that retail store employees were 50% less likely to engage in prosocial behaviorsmd
