Astronomy satellites - Hubble Space Telescope
Astronomy satellites - Hubble Space Telescope
An astronomy satellite is basically a large telescope floating in space. Because it is not confused in orbit around the Earth, the view that the satellite is not clouded by the gases that make the Earth's atmosphere, and infrared imaging devices by the heat of the earth. Astronomy Satellite, then "see" the room up to ten times better than a telescope of similar strength to the earth. Can you guess what kind of things you should looking for an astronomical satellite?
These are some pictures taken by the astronomy satellite Hubble of stellar phenomena like supernovas, distant galaxies, black holes, and quasars:
1-Supernova:
A supernova is a violent stellar explosion that destroyed a star when it expels the products of nuclear burning in the gas between the stars. The image of a supernova 20 million light years from Earth, was taken by the Hubble Space Telescope. Brightest supernova was about 100 million times brighter than the sun. The material that makes up the sun, the earth, and our bodies was once inside the star exploded long before the solar system was formed.
2-Deep Space:
Was taken by the Hubble Space Telescope, this image shows what the Hubble can see when you look in the room. Hubble is in low Earth orbit, but uses special telescopes and cameras to take pictures. This image also shows galaxies, stars and other stellar phenomena.
3-Black holes:
Black holes are mysteries to astronomers. Nobody has ever actually seen a black hole, but scientists know they exist. A black hole is essentially a huge gravitational field so strong that it traps everything in its path, including light.
4-A Quasar:
Quasars put enormous amounts of energy from a small source. The only more intense concentrations of energy in the known universe are considered. They shine with the light of hundreds of galaxies, but they are no larger than our solar system. This is a Hubble Space Telescope image of a quasar billions of light years away. In this picture, the quasar in a galaxy merger.

By analysis of the electromagnetic spectrum, the different wavelengths of light (eg, UV, X-rays, visible spectrum, microwaves, and gamma rays) make a picture of something far away in space. So are the images that come from Hubble and other astronomical satellites are not pictures of a normal camera, but the pictures from the analysis of the electromagnetic waves generated - waves, the light spectrum that.
Astronomy Satellites have many different applications:
Astronomy satellites are different from space exploration and satellites that collect their data in Earth orbit. Satellites are really space exploration probes sent into deep space.
