Kanishka NaikA supernova remnant (SNR) is the structure remaining after a star explodes as a supernova. It consists of ejected stellar material and an expanding shock wave that sweeps up and heats surrounding interstellar gas.

Chlorine and potassium enrichment in the Cassiopeia A supernova remnant - Nature Astronomy
XRISM observations show the presence of odd-numbered elements chlorine and potassium in Cas A. These findings suggest that stellar activity plays an important role in cosmic chemical evolution, enriching space with elements vital for planets and life.
StellarSnap📸 Supernova Remnant Simeis 147
Simeis 147, also called the Spaghetti Nebula, is a vast supernova remnant 3,000 light-years away in Taurus and Auriga. Glowing hydrogen and oxygen filaments stretch across a region six times the width of the full Moon. A pulsar marks the collapsed core of the original star.

📸 Veil Nebula: Wisps of an Ancient Supernova
About 7,000 years ago, a star exploded in the Milky Way, creating the Veil Nebula. Once as bright as a crescent Moon, it now appears as delicate filaments of gas in the constellation Cygnus. This image from Kuwait in 2024 shows hydrogen in red and oxygen in blue.
