Photo: Wildfires’ Nighttime Glow Spied From Space

A satellite captured eerie images of wildfires burning through the night in the far reaches of Siberia, a region regularly racked by massive burns during the summer months.

Satellites have been able to spy wildfires for years by searching out heat anomalies along the surface of the Earth, but an instrument aboard the Suomi National Polar-Orbiting Partnership satellite actually can spot the glow of fires at night in the visible spectrum, as shown in an image captured on Aug. 3.
