Explore Remnant Cassiopeia, Supernova Remnant and more!

Supernova Remnant of Cassiopeia A is the remnant of a once massive star that died in a violent supernova explosion 325 years ago. It consists of a dead star, called a neutron star, and a surrounding shell of material that was blasted off as the star died.

Galaxies, Stars and Nebulae series Cuddle up to the stars with this gorgeous fleece blanket. It features Cassiopeia A, the youngest supernova remnant in the Milky Way. In beautiful colors that show astronomers what's going on, you can just focus on how lovely it looks :). Perfect for those star-gazing evening under the sky or to just snooze curled up on the sofa! image code: cassasn

For the first time ever astronomers have been able to look inside the heart of an exploding star, using a space telescope to peer into the radioactive corpse of Cassiopeia A, a star that was once eight times the size of the Sun.

"The colorful streamers that float across the sky in this photo taken by NASA's Hubble Space Telescope were created by one of the biggest firecrackers seen to go off in our galaxy in recorded history, the titanic supernova explosion of a massive star. The dead star's shredded remains are called Cassiopeia A, or "Cas A" for short. Cas A is the youngest known supernova remnant in our Milky Way Galaxy and resides 10,000 light-years away in the constellation Cassiopeia."
