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?
Life as we know it doesn't thrive on planets without ozone layers. A new instrument slated for launch to the ISS will monitor Earth's protective ozone shell with greater depth and precision than ever before.
Glowing electric-blue at the edge of space, noctilucent clouds have surprised researchers by appearing early this year. The unexpected apparition hints at a change in the "teleconnections" of Earth's atmosphere.
Arctic permafrost soils contain more accumulated carbon than all the human fossil-fuel emissions since 1850 combined. Warming Arctic permafrost, poised to release its own gases into the atmosphere, could be the "sleeping giant" of climate change.
California is experiencing a historic drought--by some measures the deepest in more than 100 years. NASA researchers are investigating a number of explanations for what the underlying cause may be.
NASA and JAXA are about to launch a new satellite that can see through storms, tracking rain and snow around the globe better than any previous observatory. The Global Precipitation Measurement Core Observatory is scheduled to lift off from Japan on Feb. 27th.
A new study led by NASA researchers shows that half-a-dozen key glaciers in the West Antarctic Ice Sheet are in irreversible decline. The melting of these sprawling icy giants will affect global sea levels in the centuries ahead.
The Jason-2 satellite sees something brewing in the Pacific. Researchers say it could be a significant El Niño with implications for global weather and climate.
