The bright stars in the lower right hand corner are Hodge 301, located in the Tarantula Nebula within the Large Magellanic Cloud. These bright exploding stars send matter hurling through space at speeds up to 200 miles per second. This matter causes the sheeting seen in the upper left of the image.
