NASA’s Aeronomy of Ice in the Mesosphere (AIM) satellite has captured five complete polar seasons of noctilucent (NLC) or “night-shining” clouds with an unprecedented horizontal resolution of 3 miles by 3 miles. Results show that the cloud season turns on and off like a “geophysical light bulb” and they reveal evidence that high altitude mesospheric [...]

An investigation by the University of Kansas’ Adrian Melott and colleagues reveals a promising new method of detecting past comet strikes upon Earth and gauging their frequency
LAWRENCE, Kan. — It’s the stuff of a Hollywood disaster epic: A comet plunges from outer space into the Earth’s atmosphere, splitting the sky with a devastating shock wave [...]
