No they do not, or use gamma ray telescopes either. Not ground based.
Their eyes, ground-based telescopes, space telescopes.
Telescopes
Astronomers use radio telescopes, infrared telescopes, and space-based telescopes to map the shape of the Milky Way. They measure the positions and motions of stars, gas, and dust to create a three-dimensional map of our galaxy.
Astronomers typically look through telescopes at the stars to study celestial objects such as planets, stars, galaxies, and other phenomena in the universe. They use telescopes to gather data and make observations that help expand our knowledge of the cosmos.
Many people use a telescope. Astronomers, scientists, astronauts, cosmic data analysts. Even anyone who merely has a curiosity and wishes to know what is beyond our atmosphere uses a telescope.
The telescope wasn't invented until about 1604, so "early" astronomers had no telescopes.
Yes, both of them. And they also use reflecting telescopes.
Their eyes, ground-based telescopes, space telescopes.
Telescopes
We use telescopes or satellites
they use space probes,satellites,and of coarse,telescopes.
Astronomers can use their eyes to study the stars. They can also use various telescopes that either refract, reflect, and detect exotic formations.
Mainly visual and radio. But there are Xray, UV and IR.

Astronomers cannot locate extrasolar planets with telescopes because these planets are outside of our solar system and too far away for telescopes to directly observe. Instead, astronomers use indirect methods such as radial velocity and transit techniques to detect these distant planets.
Astronomers use telescopes to study stars and planets by capturing light from these celestial objects and analyzing it. They can gather data on the properties of stars and planets, such as their temperature, composition, and distance from Earth, to deepen our understanding of the universe. Telescopes come in various forms, such as optical telescopes, radio telescopes, and space telescopes like the Hubble Space Telescope.
