Hubble's Greatest Snaps
Watch this and other space videos at http://SpaceRip.com Here's Hubble's best year by year from HubbleCast: 1990: Saturn Among the first images to be sent back from Hubble after its launch in April 1990, this image of Saturn is good by the standards of ground-based telescopes. 1991: Orion Nebula Although not perfectly sharp, this early image of the Orion Nebula nevertheless shows the rich colours and structures of this bright star-forming region. 1992: Herbig-Haro 2 Throughout the region of the Orion Nebula are numerous streamers of gas that come from newborn stars, known to astronomers as Herbig-Haro Objects. 1993: Messier 100 In late 1993, Hubble's teething problems were resolved in the first servicing mission. Before-and-after images of the core of spiral galaxy Messier 100 show how this dramatically improved the telescope's image quality. 1994: Shoemaker-Levy 9 hits Jupiter Soon after the astronauts repaired Hubble during the first servicing mission, comet Shoemaker-Levy 9 collided with Jupiter. 1995: Eagle Nebula Hubble's image of the 'pillars of creation' in the Eagle Nebula is one of its most famous. These huge, dusty structures enshroud pockets of ongoing star formation. 1996: NGC 6826 This image from 1996 shows a planetary nebula, which represents the other extremity of a star's life from the Eagle Nebula. Planetary nebulae form when Sun-like stars puff out their outer layers as they run low on fuel. 1997: Mars NASA's Mars Pathfinder probe was en route to Mars in 1997 while Hubble took this image. 1998: Ring Nebula Another planetary nebula, the Ring Nebula is one of the most famous. 1999: Keyhole Nebula The Keyhole Nebula, part of the larger Carina Nebula is another bright star-forming region. 2000: NGC 1999 Not all nebulae glow brightly. NGC 1999 contains a dark patch silhouetted against a brighter background which reflects starlight. 2001: ESO 510-G13 Hubble's image of this galaxy shows the dramatic deformations that can occur after collisions between galaxies. 2002: Cone Nebula Further upgrades in 2002, including the installation of the Advanced Camera for Surveys increased resolution and picture quality again. Hubble's ultra-sharp image of the Cone Nebula demonstrates the new instrument's capabilities. 2003: Hubble Ultra Deep Field Usually astronomers know what they're going to look at when they plan their observations. For the Hubble Ultra Deep Field, observed over 11 days between September 2003 and January 2004, they did not. 2004: Antennae Galaxies The dramatic collision of two spiral galaxies is visible in this image of the Antennae Galaxies. The bright pink patches visible across much of the vista are pockets of star formation triggered by the gravitational interaction of the galaxies. 2005: The Orion Nebula This image of the Orion Nebula is one of the largest and most detailed ever made. 2006: Messier 9 Globular clusters, roughly spherical collections of stars, contain some of the oldest stars in our Milky Way. Hubble's high-resolution observations allow astronomers to discern individual stars right into the centre of these clusters. 2007: NGC 4874 This image of NGC 4874, a galaxy in the Coma Cluster, was taken with the Advanced Camera for Surveys just two days before it suffered an electronic failure in January 2007. 2008: NGC 2818 This image of planetary nebula NGC 2818 dates from this period. It is worth noting that even with its capabilities constrained, Hubble was still able to produce images that compete with any telescope on the ground. 2009: Bug Nebula In 2009, astronauts travelled to Hubble for another servicing mission, which installed new and upgraded cameras. The Bug Nebula was one of the first images sent back: Hubble was back in business. 2010: Centaurus A Using its new instrumentation, Hubble peered into the heart of Centaurus A, a dramatically dusty galaxy. 2011: Tarantula Nebula Just published in April 2012, this image of the Tarantula Nebula combines a mosaic of Hubble observations, which capture the detail and structure of the nebula.
