NASA images: 10 pictures of star clusters, galaxies, nebulae captured by NASA

NASA's Wide-field Infrared Survey Explorer (WISE) mission captured this mosaic of the Heart and Soul nebulae.

This image combines data from four space telescopes to create a multi-wavelength view of all that remains of RCW 86, the oldest documented example of a supernova.

At the center of this Chandra image, a pulsar -- only twelve miles in diameter -- is responsible for this X-ray nebula that spans 150 light years.

This image from NASA’s Chandra X-ray Observatory shows the location of different elements in the Cassiopeia A supernova remnant including silicon (red), sulfur (yellow), calcium (green) and iron (purple).

This image from NASA's Spitzer Space Telescope shows the Cat's Paw Nebula, so named for the large, round features that create the impression of a feline footprint.

A new composite image of the Crab Nebula features X-rays from Chandra (blue and white), optical data from Hubble (purple), and infrared data from Spitzer (pink).

Astronomers combined several Hubble Space Telescope images to create this view of the Pillars of Creation, which are about 5 light-years tall.

NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA) detected the magnetic field streamlines shown over this image of the Keyhole Nebula

This mosaic image of the Cepheus C and Cepheus B regions in the constellation Cepheus combined data from two instruments

The star-forming nebula W51 is one of the largest "star factories" in the Milky Way galaxy.
