Spitzer's IRAC camera generated a new view of the well-known Ring Nebula, transforming it into a delicate flower resembling a camellia blossom. The flower petals are formed by infrared light from glowing hydrogen molecules ejected by a dying star. Previous images of the Ring Nebula taken by visible-light telescopes usually showed just the inner glowing loop of gas around the star.

The magnificent spiral arms of the nearby galaxy Messier 81 are highlighted in this image from NASA's Spitzer Space Telescope. The main image is a composite obtained with the multiband imaging photometer and the infrared array camera. Thermal infrared emission at 24 microns detected by the photometer (red, bottom left inset) is combined with camera data at 8.0 microns (green, bottom center inset) and 3.6 microns (blue, bottom right inset). IRAC uncovered areas in M81 where star formation is taking place, visible in this image as clumpy knots within the well-defined spiral arms. The huge amounts of hot dust revealed by IRAC, and the associated hydrogen gas, will provide raw materials for future star formation. A visible-light image of Messier 81, obtained with a ground-based telescope at Kitt Peak National Observatory, is shown in the upper right inset.
