Telescopes
A telescope is desgined to make distant objects appear closer. It is created with many lenses or curved mirrors. The main telescopes used for anatomy is the radio, infra-red, optical, ultraviolet, x-ray and gamma ray telescopes.
Radio Telescope
A radio telescope is a large sized telescope and it picks up the long radio waves. These telescopes are used to study the naturally occuring emissions from galaxies, stars and other space objects.
Infra-red Telescopes
These telescopes detect the low energy so they are emitted easily by cool objects. Infra-red telescopes pick up galaxies million of kilometers away along with cooler stars and planetary nebula which release infra-red light.
Optical Telescope
There are two types of optical telescopes, reflection and refraction. These telescopes are use to look into space from earth or look at earth from space. Optical telescopes view stars, galaxies and nebula which emits visible light.
Ultraviolet Telescope
The atmosphere protects us from certain ultraviolet radiation, these telescopes are postioned outside the atmosphere and launched into space by rockets. The sun, other stars and galaxies emitt ultraviolet radiation
X-ray Telescope
These telescopes must be placed high in the atmosphere as most of these wavelengths can not make it past the atmosphere. X-rays are produced from dwarf stars, the moon and galax clusters
Gamma Ray Telescope
High energy and high frequency waves are picked up by the gamma ray, that is placed well out of the atmosphere. High energy celestial bodies are the main producers of these rays. These celestial bodies are things such as supernovas,black holes and neutron stars.

The Hubble Space Telescope
The hubble space telescope was launched into space on April 24th 1990. The weight of the telescope is 11,110kg and is one of NASA's telescopes. It orbits just outside Earths atmosphere which allows it to take very clear photos without the background light. This telescope can observe ultraviolet, visible and near infrared lights.
