This composite image of Chandra and Hubble Space Telescope data offers astronomers an opportunity to compare where the hotter, X-ray emitting gas appears in relation to the cooler material seen in optical wavelengths. The Chandra team found that the chemical abundances in the region of hot gas were like those in the wind from the central star and different from the outer cooler material. Although still incredibly energetic and hot enough to radiate X rays, Chandra shows the hot gas to be somewhat cooler than scientists would have expected for such a system


In its first glimpse of the heavens following the successful December 1999 servicing mission, the NASA/ESA Hubble Space Telescope captured a majestic view of the Eskimo Nebula, a planetary nebula, the glowing remains of a dying, Sun-like star.


This Hubble photograph captures a small region within Messier 17 (M17), a hotbed of star formation. M17, also known as the Omega or Swan Nebula, is located about 5500 light-years away in the Sagittarius constellation. The wave-like patterns of gas have been sculpted and illuminated by a torrent of ultraviolet radiation from young, massive stars (which lie outside the picture to the upper left).


Even a relatively quiet day on the Sun is busy. This ultraviolet image shows bright, glowing arcs of gas flowing around the sunspots.


NASA's Spitzer and Hubble Space Telescopes joined forces on May 5, 2005 to create this striking composite image of one of the most popular sights in the universe. Messier 104 is commonly known as the Sombrero galaxy because in visible light, it resembles the broad-brimmed Mexican hat. However, in Spitzer's striking infrared view, the galaxy looks more like a "bull's eye." This image is featured in our Spitzer Infrared Photo Gallery
