NASA has released two striking hi-res images of our planet, which the agency has dubbed the 'Blue Marble.' Here is how the photos were captured.
As a followup to last week's wildly popular shot of our planet's Western Hemisphere, NASA has now released the flipside (which just might turn out to be the more popular track in the long run).
Scientists have only a fledging ability now, but a new approach to prediction could eventually allow forecasters to identify portions of states facing high risk for tornadoes in an upcoming month.
Solar storm: Delta Air Lines and United Airlines diverted flights over the poles to prevent loss of communications. This is the biggest solar storm in six years, says NASA.
Peak impact of the solar storm was expected Tuesday. Only a few of the strongest storms have a serious impact, but modern society is more dependent on power grids than ever.
NASA scientists also routinely monitor space weather conditions in order to protect astronauts and hardware in orbit from harmful radiation, and today's solar storm is no exception, agency officials said.
A solar flare Sunday triggered an outburst of solar material that should hit Earth Tuesday. The disturbance could lead to voltage swings on some power lines, as well as stronger northern lights.
The severe weather damaged homes in communities in central Arkansas, as well as in communities around Tuscaloosa and Birmingham, Ala. Both Alabama cities were also hit by tornadoes last April.
A barrage of charged particles triggered by this morning's solar flare is expected to hit Earth tomorrow at around 9 a.m. EST.
Northern lights show this weekend? A big solar plasma wave is heading toward Earth, and may create Northern lights or aurora borealis display by Saturday night.
