Do optical telescopes work better in space?
In space, however, telescopes are able to geta clearer shot of everything from exploding stars to other galaxies. Another disadvantage for ground-basedtelescopes is that the Earth’s atmosphere absorbs much of the infrared andultraviolet light that passes through it. Space telescopes can detect thesewaves.
What are optical telescopes used for?
Optical telescopes are used for astronomy and in many non-astronomical instruments, including: theodolites (including transits), spotting scopes, monoculars, binoculars, camera lenses, and spyglasses. There are three main optical types: 1. The refracting telescope which uses lenses to form an image.
Are there any other space telescopes?
Herschel willbe the largest, mostpowerful infrared telescope, looking at the far-infrared to sub-millimeterwavelengths of light generated by some of the coldest objects in space. Herschel is designed to look for water, both in nearby comets and faraway dustclouds, and will also peer into the womb of star formation.
What are the three types of space telescopes?
The three main types are reflecting telescopes, refracting telescopes, and catadioptric telescopes. Radio telescopes collect and focus radio waves from distant objects. Space telescopes orbit Earth, collecting wavelengths of light that are normally blocked by the atmosphere.
How far can an optical telescope see?
The Hubble Space Telescope can see out to a distance of several billions of light-years. A light-year is the distance that light travels in 1 year.

What type of telescope does NASA use?
The Hubble Space Telescope
The Hubble Space Telescope is a large telescope in space. NASA launched Hubble in 1990. Hubble is as long as a large school bus.
How far can James Webb see?
How far back will Webb see? Webb will be able to see what the universe looked like around a quarter of a billion years (possibly back to 100 million years) after the Big Bang, when the first stars and galaxies started to form.
What is the farthest thing we can see in space?
the Andromeda Galaxy
The farthest object in space that you can see with only your eyes in the night sky is the Andromeda Galaxy. It is a huge spiral galaxy, and it is the closest large galaxy to us outside of the Milky Way.
What kind of optics are used in space telescopes?
For future space telescopes of 50, 1 00, 500 meter apertures, we have developed a new type of optical design. We use a primary reflector made from segments of flat and near-flat membranes. The secondary reflector and subsequent optics are supported in separate spacecraft, flying in formation with the primary reflector.
Which is the oldest type of Space Telescope?
UV ranges listed at Ultraviolet astronomy#Ultraviolet space telescopes . The oldest form of astronomy, optical or visible-light astronomy, observes wavelengths of light from approximately 400 to 700 nm.
How big is the next generation space telescope?
The special requirements for the Next Generation Space Telescope NGST, a large space telescope that works in the thermal infrared, lead to new design choices. Ground based telescopes of 30 meters and larger are being considered. Both types of systems make evolutionary steps from current and past telescopes.
How big of a telescope is needed for space?
Telescopes are now being planned for the ground and for space that move beyond the 20t5centurydesigns. The special requirements for the Next Generation Space Telescope NGST, a large space telescope that works in the thermal infrared, lead to new design choices. Ground based telescopes of 30 meters and larger are being considered.
