The Case of the Missing Supernova - Are Neutrinos Responsible? - The Cosmic Companion April 22, 2021
Neutrinos my be responsible for a supernova -not- seen on Earth more than 300 years ago. What happened?
Happy Earth Day, everyone!
Could a missing supernova show us how neutrinos could affect supernova eruptions?

Cassiopeia A, one of the best-studied supernova remnants in the galaxy, may have revealed secrets of supernova eruptions. This magnificent collection of gas and dust sits roughly 11,000 light years from Earth. At radio frequencies above one gigahertz, Cassiopeia A is the brightest object in Earth’s sky.
NASA’s flagship X-ray telescope, Chandra, launched in 1999, remains in operation more than 20 years later. The very first target imaged by this craft was the supernova remnant Cassiopeia A (often called Cas A). A new analysis of Cas A, seen by Chandra, suggests possible answers to some of the mysteries surrounding this enigmatic object.
