The Meadow fire in Yosemite National Park is still burning, but nearly 100 percent contained now. This video by QT Luong shows the beauty and terror of wildfire.
Fire in space doesn’t act like fire here on Earth. Untethered by gravity, flames in space curl themselves into tiny balls. Here’s a new NASA video on experiments on combustion in microgravity aboard the International Space Station.
The Montreal Protocol put the brakes on ozone-depleting chemicals 30 years ago. But one compound is still abundant in Earth’s atmosphere. Where’s it coming from?
Researchers have uncovered a 77-million year old, plant eating, super-massive Titanosaur. The huge animal weighed as much as a herd of elephants.

UPDATE SEPTEMBER 2, 2014. A white plume, with a blue tint below, rose from the active fissure at Holuhraun in Iceland, which stretches to the northeast from Iceland’s Bárðarbunga volcano. The Holuhraun fissure fields have been erupting with high lava fountains since Sunday morning (August 31), with no apparent release of ash. Yesterday’s observed plume was the first such plume to be seen. It drifted east-northeast with a maximum height yesterday of 15,000 feet from the eruptive site. The plume formed a cloud with very sharp edges at the top and below, said the Icelandic Met Office (IMO), which added:
It didn‘t seem that any ash came from the cloud. The white color of the plume does not suggest any ash.
The video above shows a famous sliding stone of Death Valley’s Racetrack Playa in motion. See it? It’s the big rock in the foreground. Watching this video, you become one of the first people on Earth to see a sliding stone in motion. Although their tracks across Racetrack Playa – a dry lake bed in Death Valley – have been observed and studied since the early 1900s, no one had ever seen the stones in motion … until now. What’s more, the researchers who captured this video say they now know what causes the stones to move.
