We often talk about Type Ia supernovas: This is the 'classic' explosion where a dense, dead star (a white dwarf) pulls in too much material from a companion star. It gets too heavy, hits a critical limit, and explodes, completely obliterating itself. These are the "standard candles" we use to measure the universe. ​But what if the explosion... fails? ​Scientists have discovered a weaker, 'failed' version of this explosion, called a Type Iax supernova. ​In this case, the explosion is powerful, bu

😨 Is this the sharpest view of a Supernova explosion ever!? — mf outshone its entire galaxy for a few seconds. In 2014, astronomers witnessed SN 2014J, a Type Ia supernova in the Cigar Galaxy (M82) — just 11.4 million light-years away. 🔭 This was the closest Type Ia blast in 40 years, caused when a white dwarf stole too much material from its companion star and detonated. 💡 Light Echo: The explosion’s light bounced off giant interstellar dust clouds 300–1,600 light-years away, creating a glow

You're looking at the longest X-ray timelapse of a supernova ever captured. In 1604, a new star appeared in the night sky. It was so bright it outshone Jupiter for weeks. Today, we know what caused it: a white dwarf star exploded — a Type Ia supernova — blasting itself apart in one of the most powerful events in the universe. More than 400 years later, we’re still watching its aftermath unfold. Using 25 years of data from NASA’s Chandra X-ray Observatory, astronomers have released the longest X-

Asterion Talks on Instagram: "Kepler’s Supernova Remnant is the expanding aftermath of a Type Ia supernova—an event triggered when a white dwarf exceeded the Chandrasekhar limit after gaining mass from a companion or merging with another white dwarf. Once this critical threshold was crossed, electron degeneracy pressure could no longer counter gravity, leading to a thermonuclear runaway that unbound the star in a fraction of a second. The explosion ejected stellar material at relativistic fracti
