Illustration of the Milky Way seen from Earth where supernova accelerates cosmic rays to high energies. Some of these cosmic ray particles enterers the Earth’s…
A supernova is the colossal explosion of a star. Scientists have identified several types of supernova. One type, called a “core-collapse” supernova, occurs in the…

An enormous amount of gravity from a cluster of distant galaxies causes space to curve so much that light from them is bent and emanated…
In the late stages of binary neutron star formation, the giant star expands and engulfs the neutron star companion in a stage referred to as…

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…
