NASA scientists are once again on the hunt for greenhouse gases in the sky.

A new series of images generated with data from NASA's Soil Moisture Active Passive (SMAP) satellite illustrate the surface flooding caused by Hurricane Harvey from before its initial landfall through August 27, 2017. Harvey is now a depression spreading heavy rainfall through the south central and southeastern U.S.The SMAP observations detect the proportion of the…

Just after Tropical Storm Pakhar made landfall in southeastern China and NASA-NOAA's Suomi NPP satellite captured an image of the storm.

Inside NASA's Goddard Space Flight Center in Greenbelt, Maryland the James Webb Space Telescope team completed the environmental portion of vibration testing and prepared for the acoustic test on the telescope. 

NASA has estimated rainfall from the Pineapple Express over the coastal regions southwestern Oregon and northern California from the series of storms in February, 2017.The West Coast is once again feeling the effects of the "Pineapple Express." Back in early January one of these "atmospheric river" events, which taps into tropical moisture from as far…

An almost continuous onshore flow is expected to bring storms to California and portions of the Pacific Northwest in a very active, wet pattern over the next couple of days, according to the National Weather Service.

Late on Feb. 15, Dineo made landfall in southern Mozambique. By Feb. 17 the storm weakened to a remnant low pressure area when NASA's Terra satellite passed overhead. The Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard Terra captured a visible image that showed the center of the low pressure area over Zimbabwe and clouds…

Researchers have completed the first flights of a NASA-led field campaign that is targeting one of the biggest gaps in scientists' understanding of Earth's water resources: snow.NASA uses the vantage point of space to study all aspects of Earth as an interconnected system. But there remain significant obstacles to measuring accurately how much water is…

Mt. Erebus is at the end of our world — and offers a portal to another.It's our planet's southernmost active volcano, reaching 12,448 feet (3,794 meters) above Ross Island in Antarctica. Temperatures at the surface are well below freezing most of the year, but that doesn't stop visits from scientists: Erebus is also one of…

NASA will host a media teleconference at 3 p.m. EST Wednesday, Feb. 8, to discuss research investigations launching aboard the next SpaceX commercial resupply flight to the International Space Station. Among the investigations are experiments with potential to fight human disease and a new autonomous spacecraft docking technology for testing.
