An Infrared View of the M81 Galaxy

M81 is a grand spiral galaxy, and in this image its arms appear as green vines twisting inward toward a central bright spot. Embedded in those arms are spots of yellow and orange light. All of this is on a background dotted with red and blue pinpricks of light.

Located in the northern constellation of Ursa Major is nearby galaxy Messier 81. M81 was one of the first publicly released datasets soon after the launch of NASA's Spitzer Space Telescope in August 2003. On the occasion of Spitzer's 16th anniversary, the mission revisited this iconic object with extended observations and improved processing, as shown in this image.
