Earth's Upper Atmosphere is Cooling
New measurements from a NASA satellite show a dramatic cooling in the upper atmosphere that correlates with the declining activity of the current solar cycle. For the first time, researchers can show a timely link between the Sun and the climate of Earth's thermosphere, the region above 100 km, an essential step in making accurate [...]

UFOs This Weekend? No, Just an Experiment
Reports of UFOs skyrocketed last weekend along the east coast of the US after a NASA launched an experiment to study an unusual phenomenon called noctilucent clouds, or 'night shining' clouds. The Charged Aerosol Release Experiment (CARE) was conducted by the Naval Research Laboratory and the Department of Defense Space Test Program, created artificial [...]

Climate Change and Earth's Cryosphere
Even though most of us do not live in the polar regions or don't even see icebergs or ice sheets very often, no matter where you live, the snow and ice of the Earth’s cryosphere has an impact on your climate. NASA released an amazing new view of Earth's frozen regions today, using visual satellite [...]

Researchers Say Sun Cycle Alters Earth's Climate
If the energy from the sun varies by only 0.1 percent during the 11-year solar cycle, could such a small variation drive major changes in weather patterns on Earth? Yes, say researchers from the National Center for Atmospheric Research (NCAR) who used more than a century of weather observations and three powerful computer models in [...]

Watermelons: The Newest Renewable Energy Source
This has nothing to do with space or astronomy, but is perhaps one of the most remarkable things I have ever read. Could we one day be driving cars fueled by watermelons? Researchers say that watermelon juice can be a valuable source of biofuel, as it can be efficiently fermented into ethanol. [...]

A Day for Earth, but a Whole Week for Dark Skies
Wednesday is Earth Day, but all week — Monday, April 20 through Saturday, April 26 — is National Dark Sky Week in America, when people are asked to dim the lights to see more stars. If enough people participate, backyard and professional astronomers might be treated with a week of darker, starrier skies. The bigger idea [...]

Aerosols Could Be Responsible For Artic Warming
Since the 1890s, surface temperatures on Earth have risen faster in the Arctic than in other regions of the world. Usually, discussions on global warming tend to focus on greenhouse gases as the culprit for the trend. But new NASA research suggests about half the atmospheric warming measured in the Arctic is due to [...]

Ozone Success Story: NASA Video of Enviro Action That Worked
Imagine the year 2065. Two-thirds of Earth's ozone is gone. The infamous ozone hole over Antarctica is a year-round fixture with a twin over the North Pole. People living in mid-latitude cities like Washington, D.C., get sunburned after five minutes. DNA-mutating UV radiation is up 650 percent, with likely harmful effects on plants, animals and [...]

At Last: Successful Launch for European Climate Satellite
Europe's Gravity field and steady-state Ocean Circulation Explorer (GOCE) is headed into orbit, after a successful launch at 10:21 a.m. EDT (14:21 GMT) on Tuesday from the Plesetsk Cosmodrome in northern Russia.  The successful liftoff came after delays stretching back to last September, but Tuesday's launch went off without any complications. "It was a nice liftoff," said Mission Scientist [...]

Europe's Climate Satellite Fails to Leave Pad
Europe's Gravity field and steady-state Ocean Circulation Explorer (GOCE) seems to be stuck on the pad. The climate change satellite was expected to launch out of Russia at 14:21 GMT (10:21 EDT) today, from the Plesetsk Cosmodrome in northern Russia. The weather was fine and mission managers were optimistic with seconds to liftoff — and then, everything froze. [...]

Climate Change Satellite gets Green Light for Launch
The European Space Agency's Soil Moisture and Ocean Salinity (SMOS) satellite has been cleared for takeoff next month, following nearly a year in limbo while the mission team awaited the go-ahead from a private launch company. Originally expected to launch in 2008, SMOS has been in storage at Thales Alenia Space's facilities in Cannes, France since [...]
