An image taken on Sept. 27, 2012, and released recently by NASA's Earth Observatory, shows off the satellite's penetrating gaze with a view of low-level, marine layer clouds off the coast of California. These clouds are invisible to technologies previously used to view nighttime scenes.
If you live anywhere within the northern two-thirds of the United States, you've probably noticed that it's pretty chilly outside. The plunge in temperatures…Read More »
over the past few days comes courtesy of an invasion of Arctic air that has been captured in a mesmerizing new animation from the National Oceanic and Atmospheric Administration.
The animation, made with weather data from the NOAA/NCEP Real-Time Mesoscale Analysis, begins on Saturday (Jan. 19) with very cold air seen only over the Rockies, Montana, North Dakota, the northern half of Minnesota and the northern portions of New England. Much of the eastern and central parts of the country saw weekend weather that was balmier than usual for mid-January.
A rockfall shattered a snowy landscape and barely missed a hut full of hikers in New Zealand Monday (Jan. 21).

Cookiecutter sharks aren't very neighborly. Like most sharks (or any marine animal, for that matter), cookiecutters roam the ocean looking for food. But…Read More »
unlike typical meat eaters, these sharks don't kill their prey they just take a bite and move on.
And for the first time, scientists have found evidence that these small sharks even go after one of the world's most fearsome predators, the great white shark. Great whites are about 10 times the size of a cookiecutter shark.
With more than 300 volcanoes crowded into a finger of land roughly the size of California, Russia's Kamchatka peninsula is home to the world's highest…Read More »
concentration of active volcanoes.
Only 29 volcanoes are active, occasionally spilling lava down their slopes or shooting steam and ash into the sky. On Jan. 11, NASA's Terra satellite snapped a picture of a fearsome foursome, as a quartet of Kamchatka's volcanoes erupted at the same time.
