Geologists from Brown University have developed a promising new explanation for a mysterious type of crater on the surface on Mars.
A recent increase in polar mesospheric clouds could be due to a recent increase in space traffic, a new study suggests. Polar mesospheric clouds are diffuse collections of water ice crystals in the mesosphere near the poles ...
(Phys.org) —ESA's CryoSat satellite has found a vast crater in Antarctica's icy surface. Scientists believe the crater was left behind when a lake lying under about 3 km of ice suddenly drained.
Ocean waters melting the undersides of Antarctic ice shelves, not icebergs calving into the sea, are responsible for most of the continent's ice loss, a study by UC Irvine and others has found.
The icy Arctic is emerging as a global economic hot spot—and one that is becoming a security concern for the U.S. as world powers jockey to tap its vast energy resources and stake out unclaimed territories.
(Phys.org) —A Purdue University-led team of researchers discovered sunlit snow to be the major source of atmospheric bromine in the Arctic, the key to unique chemical reactions that purge pollutants and destroy ozone.
(Phys.org) —A constant stream of space debris flows toward Earth from the rest of the solar system. Large meteors can sometimes survive the intense friction and heat upon entering Earth's atmosphere, but by and large the ...
Millions of people in northern Europe are still battling snow and ice, wondering why they are being punished with bitter cold when—officially—spring has arrived and Earth is in the grip of global warming.
(Phys.org) —NASA's Operation IceBridge scientists have begun another season of research activity over Arctic ice sheets and sea ice with the first of a series of science flights from Greenland completed on Wednesday.
