Carina Nebula. Cassini briefly turned its gaze from Saturn and its rings and moons marvel at the Carina Nebula, a brilliant region 8,000 light years from our solar system and more than 200 light years across. Nearly every point of light in this image is a star in our galaxy, the Milky Way. The nebula is a region of gas and dust made glow by the ultraviolet light bursting from bright, hot and extremely massive young stars within (NASA Media Archives). Buy this as a superb wall poster, a canvas print or a framed print.
