Deep Space Telescope

Deep space telescopes are an advanced type of telescope that is meant to look beyond what we see in the normal night sky to the outer reaches of the universe. Much of what we see just from our eyes is contained within the Milky Way, our own galaxy. But there are still untold numbers of galaxies and formations outside of our galaxy waiting to be seen and observed.

These scopes are a bit outside the access of the hobbyist. While you can construct a very large telescope on your own, none of these will compare to the equipment available to scientist, universities, and institutions like NASA. The most famous of these deep space telescopes is the Hubble. Situated in orbit around the Earth for nearly twenty years, the Hubble has taken amazing pictures of the stars being born in addition to a seemingly limitless number of galaxies.

The Hubble could provide these images, because like other deep space telescopes it has an amazing sensitivity to light. This is done through computer imaging and mirror technology that perfectly produces images that are miniscule by the time their light reaches Earth.

Whichever scope produces the image, the scopes are used primarily to investigate galaxies. Since stars don’t free float outside of galaxies, once we start looking beyond the Milky Way, our own local stars fade away and the territory of galaxies opens up. Through comparing varies electromagnetic wavelengths and just the simple shape of these galaxies, scientists have used these scopes to better understand how galaxies are made and how many varieties exist.
