The heat is on, at least in the Arctic. Average summer temperatures in the Eastern Canadian Arctic during the last 100 years are higher now than during any century in the past 44,000 years and perhaps as long ago as 120,000 years, says a new University of Colorado Boulder study.
Scientists from NASA and the Planetary Science Institute in Tucson, Ariz., have identified what could be a supervolcano on Mars—the first discovery of its kind.
Powerful Typhoon Wipha never made landfall in the northwestern Pacific but affected several land areas there as seen by NASA's Aqua and Terra satellites. By Oct. 18, extra-tropical storm Wipha moved into the Bering Sea and was bringing rains, warmer temperatures and gusty winds to Alaska.

The discovery provides a rare opportunity to directly measure the mass of a distant galaxy.
