Giant Galaxy Cluster Magnifies the Light from a Distant Supernova and Splits It into Multiple Images People over the centuries haven’t been shy about making…
This illustration shows a massive star that is about to explode. The explosion was triggered after its dead-star companion (a black hole or neutron star)…
Fast-moving debris from a supernova explosion triggered by a stellar collision crashes into gas thrown out earlier, and the shocks cause bright radio emission seen…
This illustration depicts a collapsing star that is producing two short gamma-ray jets. Just before a massive, collapsing star explodes as a supernova, we often…

The illustration shows an aluminum-26 nucleus (green) escaping a supernova explosion. It will subsequently decay via gamma-ray emission that can be observed by satellites. Credit:…
About 2,000 light-years away from Earth, there is a star catapulting toward the edge of the Milky WayThe Milky Way is the galaxy that contains…
The image shows galaxy Arp 148, captured by NASA’s Spitzer and Hubble telescopes. Specially processed Spitzer data is shown inside the white circle, revealing infrared…
The final stage of cataclysmic explosions of dying massive stars, called supernovae, could pack an up to six times bigger punch on the surrounding interstellar…
Artist’s impression of the HD265435 system at around 30 million years from now, with the smaller white dwarf distorting the hot subdwarf into a distinct…
A star in a distant galaxy blew up in a powerful explosion, solving an astronomical mystery. Dr. Iair Arcavi, a Tel Aviv University researcher at…
