No but really, why do we all burp and fart so much?

What makes humans so damn gassy? In a recent installment of SciShow, Hank Green explores the science behind our bodies' various "gaseous emissions." » 1/11/14 3:00pm 1/11/14 3:00pm

This quasar should not exist -- and yet it does

Astronomers from York University in Canada have identified an undocumented type of quasar where gas appears to be getting sucked into a black hole. This may not sound surprising, but current theories say that isn't supposed to happen. » 11/08/13 1:19pm 11/08/13 1:19pm

Behold the Magellanic Stream that encircles the Milky Way

Eons ago, two of our satellite galaxies became locked in a cosmic game of tug-of-war. Their fierce gravitational interactions ripped out a huge ribbon of hot, potentially star-forming gas that now surrounds much of our own galaxy's southern hemisphere, as this amazing new Hubble image shows. » 8/18/13 5:00pm 8/18/13 5:00pm

Mosh Pit Physics Reduces Humanity to a Gas

By analyzing the flocking behavior of heavy metal concert goers in mosh pits, Cornell University researchers discovered that their collective actions closely approximate the way particles work in a two-dimensional gas. » 4/24/13 10:20am 4/24/13 10:20am

The Arctic is farting ancient methane into the atmosphere

OK, OK, "farting" might not be the technical term. But as long frozen ice in Arctic regions starts to melt, trapped pockets of methane gas are escaping after millennia. This could be seriously bad news for our already warming planet. » 5/20/12 2:30pm 5/20/12 2:30pm

This life-size glass skeleton is illuminated by krypton

Krypton, being what chemists call a noble gas, glows when it's housed inside of a gas-discharge lamp. Craft the lamp's glass into specific letters and you get luminescent signage — like a red, neon "Open" sign. Hand-shape your own glass, however, and you can create something way more interesting than a boring old… » 4/04/12 2:29pm 4/04/12 2:29pm

This galaxy cluster is basically drunk

Every cosmic phenomenon deserves its own unique claim to fame, but Abell 2052 deserves better than this. Its gas jerks back and forth like a drink sloshing around in a glass. It's like the cosmic equivalent of a tipsy uncle. » 1/30/12 3:43pm 1/30/12 3:43pm

Mercury-sized exoplanet is being vaporized into a cloud of gas

Something very strange is happening around the star KIC 12557548. Its light dims every 15 hours, as though a planet is orbiting around it...except the dimming varies wildly each time around. A planet is being vaporized before our eyes. » 1/22/12 1:00pm 1/22/12 1:00pm

Astronomers discover the first unchanged relics of the Big Bang

Located some 11 billion light-years from Earth are two clouds of gas. Just two billion years younger than the Big Bang itself, they appear to be the first known clouds that are completely unaltered since the birth of the universe. » 11/22/11 11:45am 11/22/11 11:45am

Within these infrared clouds, absolute darkness reigns

This image taken by NASA's Wise Satellite is in the infrared spectrum, meaning it can reveal the light that is normally hidden behind thick, dark clouds of gas. But some clouds are so dark that no light can get through. » 8/30/11 4:00pm 8/30/11 4:00pm

What makes this strange space blob glow?

That green clump might not be much to look at, but it's one of the rarest sights in the cosmos: a Lyman-alpha blob. They're among the universe's biggest structures, and only now are we starting to understand how they work. » 8/29/11 12:41pm 8/29/11 12:41pm

Why doesn't our solar system have any gas giants close to the sun?

As we learn more about far distant solar systems, it becomes clear just how weird the universe really is. And, more disconcertingly, how unusual our own solar system is. And that starts with our curious lack of so-called "hot Neptunes." » 5/29/11 1:00pm 5/29/11 1:00pm

Burping black hole creates gigantic gamma ray bubbles

We recently discovered that gigantic gamma ray bubbles were balanced above and below the center of the Milky Way, stretching out 25,000 light-years in each direction. And now we might finally know where these mysterious bubbles come from. » 3/20/11 3:15pm 3/20/11 3:15pm

Why some people fill their tires with nitrogen

One of the many special products offered to car owners to allow them to get more bang for their buck is nitrogen gas to fill their tires. But tires are tires. As long as they're not filled with gravel or anything that can explode, what difference could the gas inside them make? Supposedly, a lot. Let's examine the… » 2/22/11 7:00am 2/22/11 7:00am

Stellar nursery is a giant, gaseous mountain range

This is nebula NGC 2174, located about 6400 light-years away. This amazing photograph makes the nebula look like the peak of a giant dust mountain, with strange pink stars dominating its summit. In fact, the stars are locked in cosmic battle with the gas mountain, and it's only a matter of time before the stars emerge… » 2/09/11 11:36am 2/09/11 11:36am

Are carbon dioxide leaks killing animals in Saskatchewan?

Storage of carbon dioxide was supposed to be a boon to the environment in Canada. But are reports of dead animals and bubbling ponds signs that it's a danger? » 1/21/11 2:39pm 1/21/11 2:39pm

The Giant Underground Gas Tank Where Most Helium Is Stored

No, this isn't a secret UFO installation. It's a natural underground gas tank that contains over a billion cubic meters of helium, important in many industrial processes, located under America's Great Plains. It's covered in mines, domes, and pipelines. » 3/19/10 9:00am 3/19/10 9:00am

Fuel-Hungry Pirates Steal Used Cooking Oil to Run Their Cars

Restaurants across the United States are reporting that thieves are stealing their used cooking oil, turning it into black-market biodiesel made in garage distilleries. In many cities where biodiesel fuel is popular, restaurants can earn up to $1.25 per gallon of the used stuff. Oil pirates, however, are rarely… » 5/23/08 7:00am 5/23/08 7:00am

The Sun Hurls Continent-Sized Blobs of Gas at Us

Newly-discovered x-ray jets literally blanket the face of the sun, launching continent-sized blobs of superhot gas outwards at 200 million miles per hour. Which is just about 5% of the speed of light, and makes us second-think the chances a spaceship like the one in Danny Boyle's Sunshine might have of getting close… » 12/24/07 7:45am 12/24/07 7:45am
