This composite image of the star cluster NGC 28 contains X-ray data from Chandra, in purple, with infrared observations from Spitzer, in red, green, blue. NGC 281 is known informally as the 'Pacman Nebula' because of its appearance in optical images.
A composite image from NASA's Chandra and Spitzer space telescopes shows the dusty remains of a collapsed star, a supernova remnant called G54.1+0.3. The white source at the center is a dead star called a pulsar.
Great Observatories' Unique Views of the Milky Way
In celebration of the International Year of Astronomy 2009, NASA's Great Observatories -- Hubble Space Telescope, Spitzer Space Telescope, and Chandra X-ray Observatory -- have produced a matched trio of images of the central region of our Milky Way.
This composite image, combining data from NASA's Chandra X-ray Observatory and Spitzer Space Telescope shows the star-forming cloud Cepheus B, located in our Milky Way galaxy about 2,400 light years from Earth
For the first time, a multiwavelength three-dimensional reconstruction of a supernova remnant has been created. This visualization of Cassiopeia A, or Cas A, the result of an explosion approximately 330 years ago, uses data from several NASA telescopes.
NASA's Spitzer and Chandra space telescopes have uncovered a long-lost population of active supermassive black holes, or quasars located deep in the bellies of distant, massive galaxies (circled in blue).
This is a composite image of N49, the brightest supernova remnant in optical light in the Large Magellanic Cloud; the image combines data from the Chandra X-ray Telescope (blue) and NASA's Spitzer Space Telescope (red).
A star's spectacular death in the constellation Taurus was observed on Earth as the supernova of 1054 A.D. This composite image uses data from three of NASA's Great Observatories. The Chandra X-ray, Hubble Space, and Spitzer Space Telescope.
This new false-colored image from NASA's Hubble, Chandra and Spitzer space telescopes shows a giant jet of particles that has been shot out from the vicinity of a type of supermassive black hole called a quasar.
NASA's Spitzer Space Telescope shows the supernova remnant 1E0102.2-7219 sits next to the nebula N76 in a bright, star-forming region of the Small Magellanic Cloud, a satellite galaxy to our Milky Way galaxy.
