ALGUMAS IMAGENS

Photographer David Cortner recorded this dramatic composite sequence of the November 8 total lunar eclipse in the skies over Connelly's Springs, North Carolina. Cortner took telescopic pictures of the Moon every eight minutes, then recorded a wide-angle view in a long exposure to bring out the thickening clouds and a silhouetted landscape. Later, the views were carefully combined along the Moon's trail through the wide-angle image to create the sequence. Credit and Copyright: David Cortner

This image of the nearby spiral galaxy M101, better known as the Pinwheel Galaxy, is a three-color combination of images from NASA's Galaxy Evolution Explorer (GALEX) spacecraft. The ultraviolet light, seen in blue in the arms of the galaxy, shows young stars (only 10 million years old), while the diffuse green visible light traces stars that have been living for more than 100 years. The red visible light image shows the stars that formed over a billion years ago.

Recent solar activity has produced some spectacular aurora in areas not usually lucky enough to see them, like this dazzling red sky in Mt. Airy, Maryland. The composite image is made up of three separate eight-second exposures. Photo Credit: George Varros.
