Seven Sisters Photograph by Greg Parker, My Shot Also known as the Seven Sisters, the star cluster M45—seen in a picture submitted May 7 to National Geographic's My Shot—contains more than 3,000 stars and is one of the brightest clusters known, according to NASA. At about 400 light-years away, M45 is also one of the closest star clusters to Earth.
Dying Star Get Wallpaper Ground-based telescopes make the nebula pictured here look rectangular in shape, hence its name: the Red Rectangle. But images taken by the Hubble Space Telescope revealed that it should more accurately be called the "Red X" nebula. The nebula's unique shape comes from gas and dust emitted in cone-shaped bursts from the dying star at its center. This star, which began shedding its outer layers about 14,000 years ago, will slowly become smaller and hotter and begin to…
National Geographic: Stars in Scorpius Image courtesy NASA The star cluster Prismis 24 hangs above the monstrous emission nebula NGC 6357, seen here in this 2006 image taken by the Hubble Space Telescope. Located 8,000 light-years from Earth in the constellation Scorpius, blazing stars some hundred times more massive than our sun lie buried within the nebula and are heating up the gas surrounding the cluster, creating the cavernous bubble visible at the bottom of the image.
This star map shows the position of asteroid 2004 BL86 in the southeast late evening sky on January 26, 2015. The space rock will be easier to find around 10 to 11 pm EST as it glides past Beehive star cluster. SKYCHART BY A. FAZEKAS, SKYSAFARI
