Last month, NASA scientists got a rare chance to study "thundersnow" first-hand when a freak winter storm rolled right over their research center.

Mark your calendar. On March 19th, a full Moon of rare size and beauty will rise in the east at sunset. It's a super "perigee moon"--the biggest in almost 20 years.
Aquarius is the first NASA sensor to track ocean salinity from space, and aims to help uncover how the salinity of Earth's oceans are effecting our climate.
Record snowfall, killer tornadoes, devastating floods: There's no doubt about it. Since Dec. 2010, the weather in the USA has been positively wild. But why?
On Dec 10th, sky watchers in the western United States will witness a total lunar eclipse swollen to super-sized proportions by the Moon illusion.
Winter seems to have been on hold this year in some parts of the United States. Snowfall has been scarce in places that were overwhelmed with the white stuff at the same time last year. In this ScienceCast, JPL climatologist Bill Patzert explains what's going on.
A "ring of fire" solar eclipse is coming to the USA this spring. It's the first annular eclipse visible from the contiguous United States in almost 18 years.
Another "super-Moon" is in the offing. The perigee full Moon in May will be as much as 14% bigger and 30% brighter than other full moons of 2012.
One year after the historic tornado outbreak of April 27-28, 2011, researchers say they've learned a few things about deadly twisters. This week's ScienceCast presents some of the scientific findings that emerged from the swath of destruction.
The second full Moon of August--a "Blue Moon"--is just around the corner. It will probably look just like any other full Moon but, on rare occasions, the Moon really does turn blue. Could it happen this month?
