New Photo Map of the Milky Way Shows Never-Before-Seen Details

The European Space Agency (ESA) satellite observatory Gaia, whose mission is to produce a 3D map of the Milky Way, has sent back a new and updated map of the galaxy that contains detailed information on more than 1.8 billion sources and is being called a "treasure trove for astronomers."

Europe to Launch Massive Gigapixel Camera into Space

A 268-megapixel sensor might suffice for photographing the stars through a telescope, but apparently a sensor many times more powerful is needed for photographing alien planets from space. The European Space Agency has just finished building the largest camera ever to be used in space: a camera over three feet wide with a gigapixel sensor composed of 106 separate CCD sensors. Just to give you an idea of how powerful the camera is: it will be able to measure the width of a strand of hair from over 600 miles away, and the thumbnail of someone standing on the moon.
