A highly unusual burst of high-energy light from a nearby galaxy is linked by scientists to a neutron star merger
A star exploding is a dramatic event, but the debris the star leaves behind can be even more dramatic. A new mid-infrared image from the James Webb Space Telescope provides one stunning example. It shows the remains of the supernova Cassiopeia A (Cas A), created by a stellar explosion 340 years ago. The image shows bright colors and complex structures. Cas A is the youngest known remnant of a massive exploding star in our galaxy, offering astronomers an opportunity to understand the star's death process. Image credit: NASA, ESA, CSA, D.
