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.....»»
A supernova caused the BOAT gamma ray burst, JWST data confirms
But astronomers puzzled by the lack of signatures of expected heavy elements. Enlarge / Artist's visualization of GRB 221009A showing the narrow relativistic jets—emerging from a central black hole—that gave rise to the brig.....»»
Kamikaze bacteria explode into bursts of lethal toxins
If you make a big enough toxin, it's difficult to get it out of the cells. Enlarge / The plague bacteria, Yersina pestis, is a close relative of the toxin-producing species studied here. (credit: Callista Images) Life-fo.....»»

Dark Energy Camera captures remains of a massive star that exploded nearly 11,000 years ago in huge gigapixel image
This colorful web of wispy gas filaments is the Vela Supernova Remnant, an expanding nebula of cosmic debris left over from a massive star that exploded about 11,000 years ago. Located around 800 light-years away in the constellation Vela (the Sails).....»»
Study shows that the ATLAS detector can measure the flux of high-energy supernova neutrinos
High-energy neutrinos are extremely rare particles that have so far proved very difficult to detect. Fluxes of these rare particles were first detected by the IceCube Collaboration back in 2013......»»
Daily Telescope: Finally, we’ve found the core of a famous supernova
In the astronomy community, SN 1987A has somewhat legendary status. Enlarge / Webb has observed the best evidence yet for emission from a neutron star at the site of Supernova 1987A. (credit: NASA, ESA, CSA, STScI, et. al.).....»»
Big lemming populations are important for far more than just predators
The number of lemmings (Lemmus lemmus) in the mountains can fluctuate sharply from one year to the next. Years when populations explode are called lemming years. These population explosions are important for many other species. More predators and bir.....»»

Astronomers find first strong evidence of neutron star remnant of exploding star
An international team of astronomers including UCL's (University College London's) Professor Mike Barlow has discovered the first conclusive evidence that a neutron star exists at the center of Supernova 1987A, a star explosion observed 37 years ago......»»
Chinese astronomers find radio pulsar in a supernova remnant
Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), astronomers from the Nanjing University in China and elsewhere, have detected a radio pulsar in a supernova remnant known as CTB 87. The finding is reported in a paper published.....»»
Researchers discover cosmic dust storms from Type 1a supernova
Cosmic dust—like dust on Earth—comprises groupings of molecules that have condensed and stuck together in a grain. But the exact nature of dust creation in the universe has long been a mystery. Now, however, an international team of astronomers f.....»»
Betelgeuse before, during and after the Great Dimming
When a prominent star in the night sky suddenly dims, it generates a lot of interest. That's what happened with the red supergiant star Betelgeuse between November 2019 and May 2020. Betelgeuse will eventually explode as a supernova. Was the dimming.....»»
