Astronomers study supernova remnants like SN 1181, revealing insights into stellar collapse and cosmic phenomena.
Supernova study methods
Astrophysicists suggest that studying the collapse of a star into a supernova could be more straightforward if the event occurs in the Milky Way, using gravitational waves and neutrino fluxes generated during the explosion.Infrared observations likely
The researchers believe it is nearly certain that a supernova will be observable in the infrared spectrum within less than 50 years, though visibility in the visible spectrum remains uncertain.Historical supernova record
In 1181, Chinese and Japanese astronomers recorded a new star in the sky, which is now known to be a rare supernova explosion called SN 1181, the remnants of which are still studied today.Artist's view of SN 1181
An artist's animation shows the remnants of SN 1181, depicting the "zombie" star at the center, surrounded by a dusty shell of material ejected during the explosion.Sulfur filaments mapped
The Keck Cosmic Web Imager at the W. M. Keck Observatory mapped bright radial filaments of sulfur extending up to three light-years from the explosion site, showing they move outward at around 1,000 kilometers per second.
