At the Heart of Stellar Chaos

This infrared image taken by NASA's Wide-field Infrared Survey Explorer, or WISE, shows a star-forming cloud teeming with gas, dust and massive newborn stars. The inset reveals the very center of the cloud, a cluster of stars called NGC 3603. It was taken in visible light by NASA's Hubble Space Telescope.

The Dirt on Andromeda

This image from NASA's Wide-field Infrared Survey Explorer, or WISE, highlights the dust that speckles the Andromeda galaxy's spiral arms. It shows light seen by the longest-wavelength infrared detectors on WISE (12-micron light has been color coded orange, and 22-micron light, red).

Fornax Galaxy Cluster

This image of a dense cluster of galaxies was captured by NASA's Wide-field Infrared Survey Explorer, or WISE. The cluster, called Fornax because of its location in a constellation of the same name, is 60 million light-years from Earth, and is one of the closest galaxy clusters to the Milky Way.

Ablaze with Infrared Light

Is it a bird, or a plane? No, it's comet Siding Spring streaking across the sky, as seen by NASA's Wide-field Infrared Survey Explorer, or WISE. This movie stitches together five frames taken by WISE as it orbited Earth during its ongoing infrared survey of the whole sky. The images span about eight hours of time.
