The Language of Planetary Light

NASA's Spitzer Space Telescope finds a delicate flower in the Ring Nebula, as shown in this image. The outer shell of this planetary nebula looks surprisingly similar to the delicate petals of a camellia blossom.

Hubble-V

This infrared view of the whole sky highlights the flat plane of our Milky Way galaxy (line across middle of image). NASA's WISE, will take a similar infrared census of the whole sky, only with much improved resolution and sensitivity.

All-Sky Infrared Survey

Nearly the entire sky, as seen in infrared wavelengths and projected at one-half degree resolution, is shown in this image, assembled from six months of data from the NASA's Infrared Astronomical Satellite, or IRAS.

Cracking the Code of Faraway Worlds

This artist's animation shows a blistering world revolving around its nearby 'sun.' NASA's infrared Spitzer Space Telescope observed a planetary system like this one, as the planet's sunlit and dark hemispheres swung alternately into the telescope's view.
