Welcome to the Universe, IRAS 14568-6304. There’s no catchy name for this particular stellar object, because it’s too new to have been given one.
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…
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.
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.
Hubble has captured "a striking new image [of a] star in the process of forming within the Chamaeleon cloud [...] throwing off narrow streams of gas from its poles." Looks like the wings of an angel or a scene from Star Trek, with the Enterprise about to enter the frame.
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…
The Hubble space telescope has captured "a lidless purple eye, staring back at us through space"—a star 20,000 light-years away from us that is ready to explode at any time now, according to NASA:
I wish I could put the southern hemisphere superstar RS Puppis on top of my tree—if it weren't ten times more massive, 200 times larger, and 15,000 times brighter than the Sun. This "holiday wreath made of sparkling lights" captured by the Hubble Space Telescope is amazingly beautiful.
This star is RS Puppis, and it isn't just the stellar equivalent of a pretty face; it's absolutely crucial to our understanding of the universe. This is a Cepheid variable star, which in part means its brightness increases and decreases on an exact, predictable schedule. And because it's surrounded by a giant nebula…
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.
Located roughly 5,000 light-years from our solar system, NGC 6559 isn't one of the galaxy's bigger stellar nurseries, only measuring a few light-years across. But it packs a whole lot of cosmic chaos into that relatively small patch of space, as stars keep popping up inside the cloud.
