Revealing The Lonely Origin Of Cassiopeia A, One Of The Most Famous Supernova Remnants

Massive stars end their lives with energetic explosions known as supernovae. Stripped-envelope supernovae show weak or no traces of hydrogen in their ejecta, meaning that the star loses most or all of its hydrogen-rich outer layers before exploding.
