starry night


Overnight View of Hurricane Sandy

Hmm .. van Gough still busy?   From NASA Earth Observatory, an image of Hurricane Sandy through the night sky.
The storm was captured by a special “day-night band,” which detects light in a range of wavelengths from green to near-infrared and uses filtering techniques to observe dim signals such as auroras, airglow, gas flares, city lights, and reflected moonlight. In this case, the cloud tops were lit by the nearly full Moon (full occurs on October 29). Some city lights in Florida and Georgia are also visible amidst the clouds.
