Volcanic lightning recreated in the lab

An LMU team has, for the first time, created volcanic lightning in the lab and captured it on film. The new findings may permit rapid characterization of ash clouds released by volcanic eruptions and improve forecasting of ...

After 10 years of service, NOAA retires GOES-12 satellite

GOES-12 has seen it all, from Hurricane Katrina that hit the Gulf Coast in 2005, to the Christmas blizzard that crippled the Central United States in 2009. It even traveled south of the equator to provide coverage for South ...
