[Friday, February 9, 2007] New results obtained thanks to ESA's Cluster satellites provide a new insight into the source of the difference between the two types of electrical circuits currently known to be associated to the auroral arcs.

[Saturday, February 10, 2007] "Griffin complimented the thoroughness of the study. He stated that NASA is not funded to do anything more than the current detection program. Members discussed the origin of the congressional language and its intent."

[Saturday, February 10, 2007] More than 200 extrasolar planets have been found so far, but our knowledge about those distant worlds is very limited. In most cases we haven't seen the planets; we only know they exist because of the effect they have on the star they orbit.

[Monday, February 12, 2007] NASA scientists may have discovered how a warmer climate in the future could increase droughts in certain parts of the world, including the southwest United States.

[Tuesday, February 13, 2007] The House Committee on Science and Technology today heard from a panel of expert witnesses who warned that U.S. earth-monitoring capabilities are at risk in the coming decade.

[Tuesday, February 13, 2007] Researchers from NASA and the Scripps Institute of Oceanography, La Jolla, Calif., will unveil new results from an unprecedented study of water deep beneath the Antarctic ice sheet.

[Thursday, February 15, 2007] Astronomers have collected and analyzed a long-term set of activity and brightness measurements of a "solar twin" 18 Scorpii which exhibits brightness changes over the course of its activity cycle that are nearly identical to the Sun's.

[Thursday, February 15, 2007] Scientists using NASA satellites have discovered an extensive network of waterways beneath a fast-moving Antarctic ice stream that provide clues as to how "leaks" in the system impact sea level and the world's largest ice sheet.

[Friday, February 16, 2007] Decision-makers, scientists and local authorities require up-to-date environmental information in order to manage natural resources, respond to natural disasters and better understand climate change.

[Saturday, February 17, 2007] Taking multitasking to new heights, NASA launched the five THEMIS satellites aboard a single Delta II rocket from Cape Canaveral Air Force Station in Florida at 6:01 p.m. EST.

[Monday, February 19, 2007] Although very close to the minimum of its 11-year sunspot cycle, the Sun showed that it is still capable of producing a series of remarkably energetic outbursts - ESA-NASA Ulysses mission revealed.

[Monday, February 19, 2007] An Ohio State University geologist today outlined a new plan to oceanographers that would consolidate much of the world's studies on the Arctic region into a global observation network.

[Monday, February 19, 2007] Three hundred million years ago, Earth's climate shifted dramatically from icehouse to hothouse, with major environmental consequences. That shift was the result of both rising atmospheric carbon dioxide concentrations and the melting of vast ice sheets.

[Monday, February 19, 2007] A year of scientific collaboration and public engagement events aimed at understanding space weather and the Sun's true effects throughout the Solar System starts today.

[Friday, February 23, 2007] The International Polar Year (IPY) 2007-2008 is envisioned as an intense, internationally coordinated campaign of research that will initiate the dawn of a new era in polar science.

[Monday, February 26, 2007] NASA will send a flight surgeon, two astronauts and a Cincinnati doctor into the ocean depths off the Florida coast May 7-18 to test space medicine concepts and moon-walking techniques. It is the first undersea mission to include a NASA flight surgeon.

[Monday, February 26, 2007] Scientists aimed the South Pole Telescope at Jupiter on the evening of Feb. 16 and successfully collected the instrument's first test observations.

[Tuesday, February 27, 2007] "Flying blind" is but one of the terms that House Science and Technology Committee Chairman Bart Gordon (D-TN) used at a hearing earlier this month to describe the nation's rapidly deteriorating system of Earth observing satellites.
