Space

This image provided by NASA  shows a delicate ribbon of gas floating in our galaxy. This image,  taken by NASA's Hubble Space Telescope and assigned a red hue  by scientiests, is a sliver section of a supernova remnant from  more than 1,000 years ago. The supernova was probably the brightest star ever seen by humans, surpassing Venus as the brightest object in the night time sky, though less bright than  the moon.  This image, visible only with the Hubble's hydrogen light filter,  is a composite of hydrogen-light observations taken by two Hubble cameras.  NASA/The Associated Press
