Recent images made with the Wide Field Camera on NASA's Hubble Space Telescope have revealed the structure of a thin sheet of gas located at the edge of the famous "Great Nebula" in Orion, an estimated 1500 light years from Earth. Astronomers, who compare the appearance of this sheet of gas with that of a rippled window curtain, report that this emission traces the boundary between the hot, diffuse interior of the nebula and an adjacent dense cool cloud. The sheet is seen in light emitted by atoms of gaseous sulfur (shown in red in the photograph). This emission is strongest under conditions which... Read more

This composite image shows the location of a one-light-year square region in the Orion Nebula which was imaged by NASA's Hubble Space Telescope. The area is near the edge of a cavity of ionized hydrogen, which is heated by ultraviolet radiation from a star cluster at the center of the nebula.

This photograph, made with the Wide Field/Planetary Camera on NASA's Hubble Space Telescope, reveals the detailed structure of a newly discovered jet of material streaming away from a young star in the Orion Nebula.

NASA's Hubble Space Telescope has observed the inner core surrounding the icy nucleus of Comet Levy more clearly than can be done with ground-based telescopes

The image was taken September 27th with the HST's Wide Field/Planetary Camera, when the comet was at a distance of about 160,000,000 kilometers (100,000,000 miles) from Earth.

NASA's Hubble Space Telescope has obtained the most detailed and highest resolution optical images of the radio galaxy PKS 0521-36. The observations were made with the European Space Agency's Faint Object Camera.

NASA's Hubble Space Telescope has peered into the inner core of the nearby so-called "symbiotic star", R Aquarii, to reveal dramatic new details of the exploding star. The observations were made with the European Space Agency's Faint Object Camera.

NASA's Hubble Space Telescope has obtained the clearest pictures ever of our solar system's most distant and enigmatic object: the planet Pluto. The observations were made with the European Space Agency's Faint Object Camera.

NASA's Hubble Space Telescope has provided an unprecedented, detailed view of highly energetic events in the core of a galaxy 30 million light-years away. The observations are a first step in HST's search for super-massive black holes at the nuclei of active galaxies.

The European Space Agency's Faint Object Camera on board NASA's Hubble Space Telescope has provided astronomers with the most detailed image ever taken of the gravitational lens G2237 + 0305, sometimes referred to as the "Einstein Cross." The photograph shows four images of a very distant quasar which has been multiple-imaged by a relatively nearby galaxy acting as a gravitational lens. The angular separation between the upper and lower images is 1.6 arcseconds.

The European Space Agency's Faint Object Camera on board NASA's Hubble Space Telescope has provided a fascinating close-up view of Supernova 1987A in the Large Magellanic Cloud.
