Scientists from NASA and other agencies have concluded that the ozone hole over the Antarctic will recover around 2068, nearly 20 years later than previously believed.

When you think of lightning, you think of a thunderstorm. Many people also assume that hurricanes have a lot of lightning because they are made up of hundreds of thunderstorms.

Lightning is four times hotter than the sun. That statement usually gets people's attention when you tell them that fact. It is also a good reason to be aware of the dangers of lightning, especially as the northern hemisphere is entering summertime.

NASA's Scientific Visualization Studio (SVS), housed at NASA's Goddard Space Flight Center in Greenbelt, Md. has created a new webpage to help amateur hurricane-trackers see when each storm happened during the season and how strong it was.

Sea level isn't, well, level. Nor is the rate by which sea level has been rising over the past few decades, but the trend is clearly up. Global sea level has risen an average of three millimeters (.1 inch) per year since 1993. Rising seas have the potential to affect billions of people around the globe, not just those living near coastlines. With the ocean soaking up more heat from a warming planet and glaciers melting at a record-breaking pace, is there any way to know where and when sea level may level off?

The first images from NASA's new CloudSat satellite are already revealing never-before-seen 3-D details about clouds.

NASA and US Forest Service researchers are evaluating advanced unmanned aerial systems (UAS) technologies to expand wildfire imaging and mapping capabilities.
