A visualization showing where sizeable asteroids have hit the Earth in recent years has been released by the B612 Foundation. The US-based group, which includes a number of former NASA astronauts, campaigns on the issue of space protection. It hopes the visualization will press home the idea that impacts are more common than we think.
Parts of ancient Antarctica were as warm as today’s California coast, and polar regions of the southern Pacific Ocean registered 21st-century Florida heat, according to scientists using a new way to measure past temperatures.
Researchers have found a way to tap the sun not only as a source of power, but also to directly produce the solar energy materials that make this possible.
The hot molten rock beneath Yellowstone National Park is 2 ½ times larger than previously estimated, meaning the park’s super volcano has the potential to erupt with a force about 2,000 times the size of Mount St. Helens, according to a new study.
Data from a NASA satellite reveals temperatures in east Antarctica recently plunged below 135.8 degrees Fahrenheit, the lowest temperature ever recorded on Earth,
“I’ve never been in conditions that cold, and I hope I never am,” said ice scientist Ted Scambos of the National Snow and Ice Data Center in Boulder, Colo. “I am told that every breath is painful, and you have to be extremely careful not to freeze part of your throat or lungs when inhaling.”
For the first time, an active volcano has been spotted rumbling away under the ice sheet of west Antarctica. It’s further evidence that the frozen continent is anything but still. The heat from the volcano could speed up the demise of Antarctica’s fragile ice sheet.
At least two oarfish, which grow up to 15 metres long and live in the deep ocean, have been sighted on beaches in California without any visible signs of injury or disease, leading to speculation that they have been affected by some kind of deep underwater disturbance. Rachel Grant, a lecturer in animal biology at Anglia Ruskin University in Cambridge, said there might be some truth in the ancient Japanese legend that the appearance of oarfish precedes an earthquake. She has begun a study to test the idea.
On October 22 and 23, the Climate Reality Project is presenting “24 Hours of Reality” – a worldwide, in-depth presentation on the realities and terrible costs of climate change on our planet. Be sure to spend some online time watching, listening, and learning about this inestimably important issue that affects the lives of everyone on earth.
Massive ice channels have been found floating beneath ice-shelves in Antarctica, with some as tall as the Eiffel tower and stretching hundreds of miles along the shelf. Scientists say that the ice channels play an important role in stabilizing the ice-shelf and so can help understand how Antarctica will respond to climate change in the future. Related research has already shown that South Pole is melting from bottom up. READ MORE: Researchers Discover Massive Ice Channels in Antarctica
In the span of three days, the American Meteor Society received reports of four massive fireballs streaking across the skies over the eastern United States. Reports first came in on Thursday, September 26th, of a large fireball lighting up the morning sky over central Indiana, passing almost directly over Indianapolis…
Scientists have discovered a massive canyon in Greenland hidden under a kilometer of ice. The canyon, found by airborne radar data collected by NASA’s Operation IceBridge, is at least 750 kilometers (460 miles) long, making it longer than the Grand Canyon. In some places, it is as deep as 800 meters (2,600 feet), on scale with parts of the Grand Canyon.
It’s known as the Hum, a steady, droning sound that’s heard in places as disparate as Taos, N.M.; Bristol, England; and Largs, Scotland. But what causes the Hum, and why it only affects a small percentage of the population in certain areas, remain a mystery, despite a number of scientific investigations.
At this moment, dozens of government satellites are taking high-resolution pictures of the planet. But citizens get only limited services such as Google Earth, which provides imagery that’s sometimes 10 years old.
The skies do strange things at the NEEM camp, a remote ice-drilling and research facility on the northern Greenland ice sheet. Midnight sunshine. Low clouds of sparkling ice crystals known as “diamond dust.”
Google Earth sifted through more than 2 million images to find the clearest photos of every place on Earth, and created a browsable HTML5 animation for the whole world, with one image for every year since 1984.
