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.
Gamma, X-ray, Optical, and Radio
they did it to get more detailed pictures of space

The correct order is c) Alpha particle, beta particle, gamma ray. Alpha particles have the greatest mass, followed by beta particles, and then gamma rays which have no mass.

Yes, astronomers use ground-based X-ray telescopes to study high-energy phenomena in space. These telescopes are typically located at high-altitude sites to reduce interference from Earth's atmosphere and are used to observe sources such as black holes, neutron stars, and supernova remnants.
In low earth orbit, perigee 333 miles, apogee 344 miles, inclination 25.58 degrees, orbital period 95.40 minutes, velocity 17,000 miles per hour. Gamma ray (and x-ray) telescopes must be in space because the atmosphere is opaque to gamma rays (and x-rays).
they use radio telescopes, infrared, gamma ray, and etc.
No, it is also observed in case of UV, Xray, Gamma ray.
No, x-rays and gamma rays cannot be focused by lenses or conventional telescope mirrors. To make mirrors that will focus x-rays or gamma rays you need very shallow glancing angle mirrors, that are nearly just parabolically tapered tubes. Typically several of these tubes with the same focal point but different diameter are nested inside each other.
Hubble Space Telescope - it has been operational since 1990 and has provided numerous groundbreaking discoveries in astronomy. Chandra X-ray Observatory - it has been studying the universe in X-ray wavelengths since 1999, helping to uncover high-energy phenomena. Fermi Gamma-ray Space Telescope - launched in 2008, it observes the universe in gamma-ray wavelengths, enabling the study of extreme astrophysical processes.
