Explanation:The Hubble Space Telescope has resolved individual stars in a spectacular new image of nearby spiral galaxy M81. The feat is similar toEdwin Hubble's historic images with theMt. Wilson 100-inch Hooker Telescope in the 1920s thatresolved stars in neighboring galaxyM31. EdwinHubble was able to use individualCepheid variable stars to show that M31 was not nearby swirling gas but rather anentire galaxy like ourMilky Way Galaxy. Thisabove image invisible light taken by theHubble Space Telescope is being used in conjunction withimages being taken inultraviolet byGalex,infrared bySpitzer, andX-rays withChandra to study how stars have formed and died over the history M81. Light takes about 12 millionyears to reach us from M81.M81 is visible with binoculars toward the constellation of the Great Bear (Ursa Major).
