Earth's Gravity Seen in HD
The sleek and sexy-looking GOCE satellite has provided a new, finely detailed look at Earth's gravity – in high definition. This is the first-ever global gravity model and is based on just two months of data from the low-flying GOCE. "GOCE is delivering where it promised: in the fine spatial scales," GOCE Mission Manager Rune [...]

Earth Moved Substantially in April 2010 Earthquake
From a JPL press release. NASA has released the first-ever airborne radar images of the deformation in Earth's surface caused by a major earthquake — the magnitude 7.2 temblor that rocked Mexico's state of Baja California and parts of the American Southwest on April 4, 2010. The data reveal that in the area studied, the [...]

Time-Lapse Satellite View of Growing Oil Spill
We've featured many satellite views of the Deepwater Horizon oil spill, here on Universe Today, but this time-lapse video reveals a space-based view beginning on April 20 with the burning oil rig and, later, the ensuing oil spill through May 24. Two NASA satellites are constantly capturing images Earth, focusing on particular areas of interest, [...]

Oil Slick on the Move Towards Florida, Possibly East Coast of US
Confirming some of the worst fears about the Deepwater Horizon oil spill in the Gulf of Mexico, satellite images now show part of the oil slick has entered the Loop Current, a powerful conveyor belt-like current that flows clockwise around the Gulf of Mexico towards Florida. The Loop Current joins the Gulf Stream — [...]

NASA Technology Helping in Oil Spill Response
An advanced optical sensor built by the Jet Propulsion Lab is flying aboard a NASA research aircraft to help monitor the spread and impact of the Deepwater Horizon BP oil spill in the Gulf of Mexico via remote sensing. The Earth Resources-2 (ER-2) is outfitted with JPL's Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) and the [...]

Latest Satellite Images of Oil Spill
NASA's Aqua satellite flew over the oil slick in the Gulf of Mexico on May 4, at 18:50 UTC, or 2:50 p.m. EDT, and the Moderate Imaging Spectroradiometer, or MODIS, instrument captured this visible-light image. The bulk of the spill appears as a dull gray area southeast of the Mississippi Delta. The spill is the [...]

Spectacular Footage, Satellite Images of Eyjafjallajokull Volcano in Iceland
A volcano under a glacier in Iceland erupted Wednesday, melting ice, shooting smoke and steam into the air and forcing hundreds of people to leave their homes. The resulting ash plume has also halted air traffic over much of Europe. Scientists said the eruption under the ice cap was 10 to 20 times more powerful [...]
