There are several astronomical telescopes in orbit.
The most famous is of course the Hubble, but COROT, MOST, and the Swift Gamma-Ray Burst Observer are all visible light telescopes in orbit around Earth, and there's another - Kepler - that doesn't orbit Earth, but does orbit the Sun.
There are also a multitude of orbital telescopes that use segments of the electromagnetic spectrum other than visible. Spitzer, for example, uses infrared light (it's another solar orbiter).
Many companies sell astronomical telescopes for purchasing. Companies that sell this product include Amazon, Orion Telescopes & Binoculars, and Young Explorers.
Thousands of people still do build their own astronomical telescopes; it isn't that hard to do.
The most serious astronomical research, such as that done by the Hubble Space Telescope, is done with reflecting telescopes.
An "observatory".
All major astronomical telescopes are equipped with spectrographs, including the Hubble and Spitzer Space Telescopes.

Observatory or astronomical observatory.
Yes, professional astronomical telescopes typically have greater magnification capabilities compared to telescopes sold in stores. This allows astronomers to observe celestial objects with greater detail and clarity. Professional telescopes also have larger apertures and specialized optics to gather more light and enhance image quality.
Yes, there are telescopes aboard many satellites that perform astronomical observations.
The earth's atmosphere doesn't let these rays reach the ground, so the telescopes are placed in orbit where they can receive the rays.
Telescopes and binoculars, although a lot can be seen with an unaided eye.
A Galilean Telescope is also an Astronomical Telescope so it is just a subset of Astronomical Telescopes.
