This infrared image made by the NASA/ESA Hubble Space Telescope shows part of NGC 2174, the Monkey Head Nebula. The structure lies about 6400 light-years away in the constellation of Orion (The Hunter). The Hubble Space Telescope marks its 25th
This image made by the NASA/ESA Hubble Space Telescope shows NGC 4526. One of the brightest lenticular galaxies known, it has hosted two known supernova explosions, one in 1969 and another in 1994, and is known to have a supermassive black hole at
This image made by the NASA/ESA Hubble Space Telescope shows the tattered remains of a supernova explosion known as Cassiopeia A. It is the youngest known remnant from a supernova explosion in the Milky Way. (Photo: AP)
This image made by the NASA/ESA Hubble Space Telescope shows the Orion Nebula and the proceess of star formation, from the massive, young stars that are shaping the nebula to the pillars of dense gas that may be the homes of budding stars. (Photo:
This image made by the NASA/ESA Hubble Space Telescope shows Abell 1703 which is composed of over one hundred different galaxies whose collective mass acts as a gravitational lens. The massive galaxy cluster in the foreground bends the light rays of
This false-color image made by the NASA/ESA Hubble Space Telescope shows the Carina Nebula. Outflowing winds and intense ultraviolet radiation from the large stars shape the material that is the last vestige of the giant cloud from which the stars
This image made by the NASA/ESA Hubble Space Telescope shows M66, the largest of the Leo Triplet galaxies. It has asymmetric spiral arms and an apparently displaced core most likely caused by the gravitational pull of the other two members of the
This image made by the NASA/ESA Hubble Space Telescope shows NGC 4038 and NGC 4039, known as the Antennae Galaxies. Once normal, sedate spiral galaxies like the Milky Way, the two have spent the past few hundred million years intertwining with one
This image made by the NASA/ESA Hubble Space Telescope shows NGC 6543, the Cat's Eye Nebula. A planetary nebula forms when Sun-like stars gently eject their outer gaseous layers that form bright nebulae. In 1994, Hubble first revealed the nebula's
This image made by the NASA/ESA Hubble Space Telescope shows M106 with additional information captured by amateur astronomers Robert Gendler and Jay GaBany. Gendler combined Hubble data with his own observations to produce this color image. It is a
This image made by the NASA/ESA Hubble Space Telescope shows Messier 57, the Ring Nebula. The Hubble Space Telescope marks its 25th anniversary. (Photo: AP)
This image made by the NASA/ESA Hubble Space Telescope shows the barred spiral galaxy NGC 1300. It is considered to be prototypical of barred spiral galaxies. The Hubble Space Telescope marks its 25th anniversary. (Photo: AP)
This image made by the NASA/ESA Hubble Space Telescope shows Barnard 33, the Horsehead Nebula, in the constellation of Orion (The Hunter). This image shows the region in infrared light, which has longer wavelengths than visible light and can pierce
This image made by the NASA/ESA Hubble Space Telescope shows the star cluster Pismis 24 in the core of the large emission nebula NGC 6357. Part of the nebula is ionised by the youngest (bluest) heavy stars emitting intense ultraviolet radiation,
In this image provided by NASA/JSC, astronauts Steven L. Smith and John M. Grunsfeld are photographed during an extravehicular activity (EVA) during the December 1999 Hubble servicing mission of STS-103, flown by Discovery. With more than 1 million
This February 2010 image made by the NASA/ESA Hubble Space Telescope shows a three-light-year-tall pillar of gas and dust in the Carina Nebula which is being eaten away by the light from nearby bright stars. Inside, infant stars fire off jets of gas
This image made by the NASA/ESA Hubble Space Telescope shows galaxy UGC 10214 with the long streamer of stars. Its distorted shape was caused by another galaxy passing nearby. (Photo: AP)
This image made by the NASA/ESA Hubble Space Telescope shows the barred spiral galaxy NGC 1300. It is considered to be prototypical of barred spiral galaxies. The Hubble Space Telescope marks its 25th anniversary. (Photo: AP)
This image made by the NASA/ESA Hubble Space Telescope shows jets of gas heated to nearly 20,000 degrees Celsius traveling at more than 950,000 kilometres per hour streaming from they dying star NGC 6302, the "Butterfly Nebula" in the Milky Way
This image made by the NASA/ESA Hubble Space Telescope shows the tip of the three-light-year-long pillar in a stellar nursery called the Carina Nebula, located 7500 light-years away from the Earth. Composed of gas and dust, the structure is
This image made by the NASA/ESA Hubble Space Telescope shows the entire Crab Nebula. (Photo: AP)
This undated photo provided by NASA shows an image taken by the Hubble Space Telescope showing a breeding ground for stars in the Constellation Carina, about 20,000 light years from Earth. Friday, April 24, 2015, marks the 25th anniversary of Hubble
