Mysterious plumes of gas rising more than 150 miles above the surface of Mars have left scientists confounded. On two occasions in the spring of 2012, amateur astronomers spotted a cloud developing on the surface of the Red Planet. The plumes, which spanned about 600 miles in diameter and changed shape constantly, appeared within a few hours and remained […]

Despite no exposure to sunlight or fresh air for more than a million years, a lake located half a mile beneath the Antarctic ice sheet sustains an entire ecosystem, scientists have confirmed—raising the prospect that life might exist in similar environments elsewhere in the universe. Researchers had long suspected the existence of tiny life-forms living below the ice pack, and […]

For the first time, scientists have caught a glimpse of a black hole ejecting a hot “flare” of matter after devouring a star the size of our sun. The discovery was made thanks to the quick action of of scientists from John Hopkins University, who worked in conjunction with a team from the University of Oxford. Hubble fellow Sjoert van […]

The largest solar storm since 2005 swept across the planet this week, forcing airlines to reroute flights and disrupting communications from global positioning satellites. This spontaneous blast of solar radiation may have affected power grids and high-frequency radio communications in the northern latitudes, said the U.S. Space Weather Prediction Center. A number of airlines, which route some U.S.-Asia flights over […]

“It has happened,” said Philip Bump. For the first time in human history, atmospheric carbon dioxide levels hit a daily average of 400 parts per million (ppm) last week. “There is now more carbon dioxide in the atmosphere than at any point since 3 million years ago.” Back then, global temperatures were about 7 degrees higher, the Arctic was ice-free, […]

Scientists have found telltale evidence that an asteroid twice as large as any previously known smashed into Earth about 300 million years ago. Previously, the largest asteroid impact was believed to have occurred 66 million years ago, when a massive space rock hit what is now the Yucatan Peninsula in Mexico, causing such havoc that it led to the extinction […]

The Seabin marine waste collector shows how often the simplest solutions are the most effective. The rubbish collector, designed to float in marinas, inland waterways, residential lakes and harbors, collects floating debris and liquids by sucking water from the surface and letting if flow out through the bottom of the structure, trapping waste in a filter bag. The inventors have […]

Kīlauea is a currently active shield volcano in the Hawaiian Islands, and the most active of the five volcanoes that together form the island of Hawaiʻi. Located along the southern shore of the island, the volcano is between 300,000 and 600,000 years old and emerged above sea level about 100,000 years ago. The immediate effects of a volcanic eruption is […]

Global warming hits plateau. . . What does that mean for the threat of catastrophic climate change? Why has the warming trend slowed? Climatologists aren’t sure. What they do know is that the average air temperatures at the earth’s surface have risen only about 0.2 degrees Fahrenheit since 1998—the hottest year of the 20th century—even as humanity has continued to […]
