This giant cosmic bubble may seem an unusual sight, but in fact it’s pretty common across the Universe—because its the remnants of a dying star, otherwise known as a planetary nebula.
The most fundamental outdoor skill is also often one of the most misunderstood. Learn these five campfires and you’ll be able to cook food, scare off wild animals, stay warm or just have a bonfire on the beach. They’re simple, but everyone can probably learn something here.
Ever wondered what a dead star looks like? Then have a gander at the image above — you're looking at "Kepler's Supernova". First spotted 410 years ago today, it's the most recent supernova to have been observed without sky-gazing equipment within our own galaxy.
No, this isn't another golf ball from outer space. In fact, it's a simulated image of the interior of a supermassive star weighing 55,500 times more than our Sun.
The star Wolf-Rayet WR124 disintegrates in the constellation Sagitta, 10,900 light years from Earth. The fiery explosive halo is made of "glowing gas globs each typically over 30 times more massive than the Earth being expelled by violent stellar winds." And the incredible thing is that this is not even a supernova.
This photo of the birth of a star—newly captured by the Hubble Space Telescope—is so beautiful that it seems unreal, like a picture-perfect matte painting for a science-fiction movie. But there's no fiction in here—it's all science.
I never imagined I was going to see something like this: A video of a star bursting in space, illuminating the interstellar dust around it at the speed of light. This is not a computer simulation. It's an actual time-lapse video taken over four years by the Hubble—and scientists don't know its origin yet.
This is a grain of interstellar dust. To get one of these, your best bet is to get into a spaceship for a couple hundred years and get close enough to a red giant star, near its atmosphere. That's where they're formed and ejected into space. Or, like NASA, you can create a machine to make one from scratch—for the…
NASA has created the first ever map of radioactive material in a supernova remnant, revealing one of the biggest mysteries in the universe: How stars blow up in these explosions, sowing the universe with heavy elements like iron, titanium or gold.
In the latest issue of the New England Journal of Medicine, researchers recount the fascinating case of an electrician who, after sustaining a 14,000-volt shock to his left shoulder, presented with "bilateral stellate anterior subcapsular opacities of the lens." Translation: Starburst-shaped cataracts.
And with "just" I mean 11.4 million years ago, even while Steve Fossey just detected this bright and rare Type Ia supernova using a 'modest telescope in an unlikely spot: foggy north London.' Scientists say that it will be visible in the sky soon, as it brightens up. Here you can see the supernova appearing in the…
A team of scientists using the European Space Agency's XMM-Newton space telescope have discovered a weird dead star , which hides one of the strongest magnetic fields in the Universe.
Astronomers at the Atacama Large Millimeter/submillimeter Array (ALMA) observatory have observed something very surprising for the very first time: a weird tridimensional spiral structure inside of a dying star, one that is just like our very own Sun.
Look at this star turned into a fire dragon by a single point of nothingness with the mass of three million suns—its body twisted and deformed as a black beast 2.7 billion light-years away devours it with infinite hunger.
Pictures hacked from Hollywood stars' email accounts and phones seem to be a mainstay of popular culture these days. Chris Chaney, one of the most prolific celebrity hackers to date, was recently arrested—but GQ has a wonderful profile of the man which you really have to read.
Fake online reviews are a pain in the ass: they make interent shopping harder than it already is. But thankfully there are people out there who are developing ways of spotting and blocking rogue five-star reviews, and a new algorithm backed by Google seems to be the most effective yet.
Astronomers have found two more new planets orbiting binary stars: Kepler-34b and Kepler-35b. Their discovery, which follow the original Tatooine discovery back in September 2011, is quite important: now we know there are millions of planets orbiting binary stars.
Molecular astrophysicist Markus Hammonds gives us this perspective on how the size of a dwarf star like Sirius B looks compared to Earth. Those dwarfs are really tiny. And pretty. [Luminous Red Nova]
Back in late March, NASA's Swift satellite detected a strange and unusual energy explosion in the constellation Draco. NASA now knows what it was: "the awakening of a distant galaxy's dormant black hole as it shredded and consumed a star."
