Observations of stellar visibility by citizen scientists accurately measure the brightness of the night sky
A team of researchers from Germany, Italy, and the USA have shown that observations of stellar visibility by citizen scientists accurately measure the brightness of the night sky. The researchers published their results Thursday ...
Climate-related changes on the Antarctic peninsula
Scientists have long established that the Antarctic Peninsula is one of the most rapidly warming spots on Earth. Now, new research using detailed satellite data indicates that the changing climate is affecting ...
New study explains surprising acceleration of Greenland's inland ice
Surface meltwater draining through cracks in an ice sheet can warm the sheet from the inside, softening the ice and letting it flow faster, according to a new study by scientists at the Cooperative Institute ...
Climate models make too hot forecasts of global warming
Data from NASA's Terra satellite shows that when the climate warms, Earth's atmosphere is apparently more efficient at releasing energy to space than models used to forecast climate change have been programmed to "believe."
Stronger, more frequent tropical cyclones ahead, research says
The world typically sees about 90 tropical cyclones a year, but that number could increase dramatically in the next century due to global warming, a US scientist said Monday.
Star's 'cry' heralds new era for testing relativity
(Phys.org) -- Last year, astronomers discovered a quiescent black hole in a distant galaxy that erupted after shredding and consuming a passing star. Now researchers have identified a distinctive X-ray signal ...
'Ferrari of space' set to fall to Earth
A science satellite dubbed the "Ferrari of space" for its sleek, finned looks will shortly run out of fuel and fall to Earth after a successful mission, the European Space Agency (ESA) says.
Demise of large satellite may have led to the formation of Saturn's rings and inner moons
Simulations performed at Southwest Research Institute may explain how Saturn's majestic rings and icy inner moons formed following the collision of a Titan-sized satellite with the planet, according to a paper ...
Researchers show how far South American cities moved in quake
The massive magnitude 8.8 earthquake that struck the west coast of Chile last month moved the entire city of Concepcion at least 10 feet to the west, and shifted other parts of South America as far apart as ...
Unusual gamma-ray flash may have come from star being eaten by massive black hole
A bright flash of gamma rays observed March 28 by the Swift satellite may have been the death rattle of a star falling into a massive black hole and being ripped apart, according to a team of astronomers led ...
A solution to Darwin's 'mystery of the mysteries' emerges from the dark matter of the genome
Biological species are often defined on the basis of reproductive isolation. Ever since Darwin pointed out his difficulty in explaining why crosses between two species often yield sterile or inviable progeny (for instance, ...
Scientists discover satellites captured Chelyabinsk meteor debris trail
Lost medieval city found in Cambodia
A lost medieval city that thrived on a mist-shrouded Cambodian mountain 1,200 years ago has been discovered by archaeologists using revolutionary airborne laser technology, a report said.
Arctic ice shrinking in volume, too, ESA reports
Arctic sea ice, which has been declining in area by unprecedented amounts in summer, is also falling in volume, the European Space Agency (ESA) said on Wednesday.
