Is it possible to find trace evidence of supernovae from millions of years ago in the sediment lining the ocean floor? One astrophysicist has spent the better part of a decade trying to find the proverbial smoking gun to prove that it is. And now, it seems, he has succeeded.
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.
When a star dies and erupts as a supernova it can produce a short, sharp shockwave that astronomers call a “shock breakout.” For the first time ever, astronomers have captured such an event as optical light.
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.
Exploding stars are always a sight to behold, but not all supernovae are created equal: Some, for instance, may give birth to thousands of Earth-like worlds.
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.
Fruit may be the best thing to blow up because all that pulp, juice, seeds, peel, skin make for great gory guts in explosions. This slow motion explosion of an orange is as good as explosions get. In fact, it almost looks like a mini version of our Sun going supernova and exploding on itself.
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.
Once again, the Universe amazes me with a never-before-seen display of color and shapes that defies belief. You are looking at Puppis A, a supernova remnant that is 7,000 light years away and is 10 light years across (!) And yet it looks like microscopic view of a coral here on Earth. Amazingly beautiful.
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.
Scientists at the Vulcan laser lab in the United Kingdom have used three high powered light beams "focused on a carbon rod target not much thicker than a strand of hair "to create a supernova right here on Earth—a tiny supernova, but a supernova nonetheless.
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.
Even if Hubble had been a total disaster spewing one crappy image after the other for more than two decades, it would have been worth it just for this single image: a supernova explosion in the galaxy M82, taken on January 31, as it approached peak brightness.
