A telescope helps you to see objects in the distance better. The electromagnetic spectrum is a collection of all waves. Light is part of the electromagnetic spectrum albeit a very small part. X-rays, gamma rays, infra-red, ultra-violet, etc. are all members.

A telescope is an optical instrument used to observe distant objects by collecting and focusing light, while a satellite is a man-made object placed into orbit around Earth or other celestial bodies for various purposes like communication, navigation, and scientific research. Telescopes can be on Earth or in space, while satellites are typically spacecraft launched into orbit.
A Galilean Telescope is also an Astronomical Telescope so it is just a subset of Astronomical Telescopes.
a major difference the huble space telescope is in orbit while the regular is in use only on the ground
The difference is the same as in other contexts.* "Artificial" means that something was created by humans. * "Natural" means that it was NOT created by humans.
The main difference between a telescope and a satellite is their location and function. Telescopes are ground-based instruments that observe objects in space from Earth, while satellites are man-made objects that orbit Earth or other celestial bodies to perform various tasks such as communication, weather monitoring, or Earth observation. Telescopes are used for observing distant objects in space, while satellites are used for a wide range of applications beyond just observing space.
"Kepler" is actually an observatory, rather than a telescope. It does, however, operate in space. "Hubble" is a telescope, in the true sense of the word and, again, it operates in space.
