The Earth's atmosphere is about 120 miles thick and anything we see from the surface of the Earth is distorted by the water vapor and debris that is in the air. If you are in space you do not have this distortion. The Hubble Telescope is a good example of space based telescopes.
Scientists have put telescopes in space to avoid interference by the atmosphere.

Certain wavelengths of light such as infrared, Xrays and gamma rays cannot penetrate the Earths Atmosphere. Also, water in the atmosphere will interrupt incoming light.
To avoid interference from the earths atmosphere
Their eyes, ground-based telescopes, space telescopes.
Astronomer
Some of the best telescopes are in orbit because the earth atmosphere distorts the light from distant stars,which is something scientist and astronomers would rather avoid.
All of the observational tools needed by astronomers: astrolabes, quadrant, clocks, sextants, octant, spectrographs, polarimeters, telescopes, optical mount, radio telescopes, space telescopes, etc. are products of various technologies.
-Stars -Asteroids -planets And everything else in space.
Their eyes, ground-based telescopes, space telescopes.
We use telescopes or satellites
Astronomer
they use space probes,satellites,and of coarse,telescopes.
To study outer space in greater detail through magnification.
telescopes, spectrograph's, screw drivers, and lots of Physics!
to get every view
They are too big and heavy for it to be possible to launch them into space.
They can be seen in telescopes and instruments can measure their light, etc.
Optical telescopes are placed high to avoid having to look through the thickest part of the atmosphere. Radio telescopes are place in valleys to avoid the effects of man-made electrical noise in the telescope.
The telescope wasn't invented until about 1604, so "early" astronomers had no telescopes.
