Have you ever wondered what can be seen beyond the naked eye? Scientists and other mechanics work together to build significant and intellegent space telescopes. Each space telescope has a different set mission. These great telescopes are the ATM (Apollo Telescope Mount), HST (Hubble Space Telescope), and the Spitzer space telescope. With these special designed telescopes, a human can see and discover things in space like never before.

I hope you mention one particular group of telescopes... NASA's "Great Observatories". You've already got 2 of them on your list. Also don't forget the first good one... the ATM! (no, that's not a joke)

I Apollo Telescope Mount (ATM) Edit

A. OverviewEdit

  1. ATM or the Apollo Telescope Mount, is the name given to a solar observatory. Apollo was attached to the first U.S. space station, Skylab, in May of 1973. To operate Apollo, astronauts had to manually control it's components from within Skylab. This telescope was the biggest and most powerful solar observing telescope at the time. It was the first to find sun spots with a broad range of the electromagnetic spectrum of visible light through x-rays. A big accomplishment for this telescope was gaining increased understanding of dynamic characteristics of hot regions on the solar surface and also the behavior of the newly discovered coronal holes. After three missions of exploration, the ATM crashed down with the Skylab in July 11, 1979.

    The Apollo Telescope Mount completed.

II. Hubble Space Telescope (HST) Edit

A. OverviewEdit

  1. Another fascinating space telescope is the HST. The Hubble Space Telescope orbits around the earth. In 1990, Hubble was launched in space to play a big part in the field of astronomy. Hubble carried five great instruments but two instruments failed to operate. Both of the instruments were valuable cameras. Even with these fatal failures, Hubble still managed to make discoveries. Two critical discoveries were dark energy and the comet collision with Jupiter. Scientists believe that dark energy is a force that is changing our universe and is believed to be forcing our galaxies farther and farther apart.In 1994, Hubble captured images when the comet Shoemaker-Levey 9 collided with Jupiter.

B. DiscoveriesEdit

The Hubble Telescope has so far made ground-breaking discoveries in astronomy. One of these discoveries includes the measuring the distance between the “Cepheid variable” stars more accurately than ever before and thus a better rate of universe expansion. The telescope was also able to capture images of the collision between Comet Shoemaker-Levy 9 with Jupiter in 1994. Others discovered by the Hubble would be the proto-planetary disks in the Orion Nebula, which suggests the presence of extra-solar planets around sun-like stars. This telescope has been able to take such images and reveal galaxies that are billions of light years away.

Over the recent years of the twenty first century the Hubble is still making more and more discoveries. Here are some discoveries:

  • On February 22, 2006, the Hubble confirms that Pluto has two new moons.
  • On February 28, 2006, the Hubble has taken a snapshot of the largest and detailed spiral galaxy.
  • On April 15, 2007, the Hubble finds a ring of dark matter.

  • On January 1, 2008, the Hubble finds glowing rings within space.
  • On January 15, 2009, the Hubble locates a Nebula in a cluster.

  • On April 14, 2009, the Hubble catches a black hole flaring up.

  • On May 5, 2010, the Hubble catches an image of the planet, WASP-12b being eaten by another star.

III. Spitzer Space Telescope Edit

A. OverviewEdit

  1. August 25, 2003 marks the day the Spitzer Space Telescope was first launched into space. This major telescope is the largest infrared telescope ever launched to obtain images and spectra. Many changes have been made to Spitzer on its journey. Such as its orbit components, it has the ability to make its own choice of orbit. It became more lightweight, and cryogenic optics. With these innovations Spitzer, made many discoveries. Such as atomosperes on the planets outside of our solar system. Also it helped find planets in the making in 2005.
