The Hubble telescope by Maiki Morrogh

 These facts are about what the hubble telescope saw.


Facts: NASA astronauts Steven Smith and John Grunsfeld perform a spacewalk during a December 1999 mission of the space shuttle Discovery to service the Hubble Space Telescope.

  • Hubble flew into orbit on April 24, 1990, aboard Discovery. The first major optical telescope to be placed in space, Hubble is currently located about 340 miles above Earth’s surface where it completes 15 orbits per day — one approximately every 95 minutes. The satellite moves at the speed of about five miles per second, fast enough to travel across the United States in about 10 minutes. 

  • Here's a small sampling of some of the dazzling images captured by Hubble that have changed the way we view the universe. 
    • Fact 2: Southern Crab Nebula,In celebration of the 29th anniversary since Hubble's launch,
    • astronomers captured this festive, colorful image of the tentacled Southern Crab Nebula
    • (not to be confused with the Crab Nebula)

    • This nebula, a giant cloud of dust and gas, is officially known as Hen 2-104.
    • It's located several thousand light-years
    • from Earth in the southern hemisphere constellation of Centaurus.
    • It appears to have two nested hourglass-shaped structures that were sculpted by a
    • whirling pair of stars in a binary system.
    • The duo consists of an aging red giant star and a burned-out star, a white dwarf.
    • The red giant is shedding its outer layers.
    • Some of this ejected material is attracted by the gravity of the companion white dwarf.
