Look up and you might see the bright constellation Cassiopeia trace a zig-zag across the sky as it seemingly always has. But almost 450 years ago, it was the source of surprise: A bright flash, Tycho’s supernova, or “SN 1572" as scientists call it. This was one of the few supernovae humans have been able to see with…
Astronomers have compiled a stunning composite image of an extraordinarily large explosion that’s being powered by one of the largest supermassive black holes known to science.
An exceptionally bright supernova discovered last month appears to shine brighter than 500 billion Suns. That’s twice as luminous as the previous record—but because it’s low in hydrogen, scientists are confused as to where this exploding star got all its energy.
Our Sun has been quite active over the past several weeks, ejecting giant strands of stellar debris into the cosmos. NASA scientists recently captured a video of one particularly eye-catching explosion that produced a dramatic arch across the sun’s surface.
An international team of astronomers have finally caught a glimpse of an expanding thermonuclear fireball from an exploding white dwarf. It's the first time this kind of data has ever been captured, allowing the researchers to study how the fireball evolves and rapidly expands into space.
The recent detection of a gamma-ray burst from a massive blue supergiant is helping astronomers understand how the universe's primordial stars ended their lives in cataclysmic explosions. But more than this, it revealed several features never seen before in a stellar explosion.
Earlier this year, astronomers detected one of the brightest explosions ever seen in space. Now, some seven months later, the unusual event has been confirmed as a gamma-ray burst — and it's changing the way we think about these cataclysmic explosions.
As if we didn't already have enough to worry about, a pair of scientists are warning that it's theoretically possible to deliberately detonate the Sun. Called an "artificial supernova," this event could represent a new existential risk to the human species. Or maybe, these guys don't know what the hell they're talking…
