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.

explorenasa Happy St. Patrick's Day! 🍀🍀💚🌈🌈Over 11,000 years ago, a massive, supergiant star came to the end of its life. The star's core collapsed to form an incredibly dense ball of neutrons, and its exterior was blasted away in an immense release of energy astronomers call a supernova.  The light from this supernova first reached Earth from the direction of the constellation Cassiopeia around 1667 A.D. If anyone alive at the time saw it, they left no records. It is likely that large…

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."

The expanding remains of a supernova explosion in the Milky Way are seen in this composite image. Supernova remnant G1.9+0.3 is the youngest known supernova remnant in the Galaxy — about 140 years old — easily beating the previous record of about 330 years for Cassiopeia A.
