Astronomers have used 15 years of X-ray data to make this video of the remnants of a white dwarf that famously exploded in 1572. Nearly 450 years later, the debris from the explosion is still expanding.
Ancient astronomers have long been providing observations of supernovae, such as SN 185 by Chinese astronomers in 185 AD, SN 1054, which produced the Crab Nebula, and SN 1006, the brightest stellar event ever recorded. Now, a new paper has uncovered a new observation of the 1006 event.
An international team of astrophysicists has discovered the brightest supernova yet, briefly blazing fifty times brighter than the entire Milky Way galaxy. It’s a strange new way for stars to die.
The Hubble Space Telescope took a new image of the Veil Nebula, a supernova remnant from a star that exploded 8,000 years ago, and made this truly spectacular flyover visualization of the beautiful ripple in space that you can see below. In the 3D visualization, red is sulfur, green is hydrogen and blue is oxygen.
When the supernova burned itself out, all that was left was fragments of dust and light. This fantastic image comes from Don Goldman, and it’s a beautiful one.
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.
Stars may be spherical, but that doesn’t mean they explode in a symmetrical and uniform fashion. As a new study shows, stars dramatically writhe and contort before going supernova, blasting their cores in one direction and ejected material in another.
It's not every day we get to see a supernova, and a single exploding star split into four images is an absolute first. Here's how it happened.
This is the aftermath of an exploding star (G299, by name) and it's undoubtedly beautiful. But what it also is is very, very strange — and it just might turn all that we know about how stars explode on its head.
The supernova is a well-publicized and frightening phenomenon. There's also a phenomenon known as an "unnova." You don't want it in your backyard any more than you want a supernova.
What makes a dead star explode? Scientists have long suspected a mechanism for making a white dwarf go supernova, but they weren't able to confirm it — until now.
The Chandra X-ray observatory has been observing the universe in X-ray wavelengths for fifteen years. The space telescope's scientific highlights gallery has so much gorgeous X-ray goodness that it's hard to pick favourites. Need to be swept away by the sheer beauty of space? We've got you covered.
When the Chandra X-ray Observatory celebrates a launch anniversary, it goes big with exploding stars and rotating neutron stars. Today marks 15 years of precision X-ray investigations of stars, galaxies, black holes, neutron stars, and even dark energy. NASA celebrates with supernova and pulsars.
Stars are colossal fusion reactors, burning hydrogen into helium. As the nuclei fuse lighter elements into heavier elements, massive amounts of energy are released. A new game sets you the task of nucleosynthesis, building hydrogen into iron, and it's surprisingly fun.
When supernova explode, they fling gas out into space, creating beautiful, gauzy remnant for us to drool over. Supernova remnant G352 is pretty, but weird. It's collecting extra material, misplaced its neutron star, and looks dramatically different depending on the wavelength.
What happens to a pair of binary stars when one of them goes supernova? These gorgeous shots of a binary star, in which one went supernova and the other remained intact, gives us one answer to that question.
Three days ago, a white dwarf went supernova in nearby Galaxy M82. A starburst galaxy, M82 is a popular target for telescopes on account of its brightness. But its newly formed supernova, which astronomers have named SN 2014J, just became the brightest object in all the galaxy – and it's only going to get brighter.
A white dwarf exploded last night up in the Cigar Galaxy (also known as M82 to its friends), creating the closest supernova we've seen in the last 25 years — and one of the brightest, too.
See that reddish cloud inside this supernova's shockwave? It's a massive plume of dust that formed shortly after the star ripped itself to shreds. The observation was made using the the brand new ALMA telescope — and it's one that will help explain how galaxies got their dusty and dim complexion.
