What equipment does an astronomer need?
Beginning skywatchers will need to choose between four kinds of telescopes: reflectors, refractors, hybrid and Dobsonian. Space.com’s Best Telescopes for the Money can help.
What is the most important instruments used by astronomers?
Telescope, device used to form magnified images of distant objects. The telescope is undoubtedly the most important investigative tool in astronomy.
What type of equipment on Earth and in space do astronomers use?
Astronomers use a number of telescopes sensitive to different parts of the electromagnetic spectrum to study objects in space. Even though all light is fundamentally the same thing, the way that astronomers observe light depends on the portion of the spectrum they wish to study.
What are astronomical instruments?
Astronomical instrumentation are the tools used to observe objects and phenomena that occur in space. These can include both terrestrial and satellite-borne telescopes.
Which instrument is used to see planets?
Spectrographs are used to see what the light we receive from the stars and planets is made of, which allows the astronomers to tell what is the composition of the planets.
What is the oldest tool used astronomy?
Historically, optical astronomy, also called visible light astronomy, is the oldest form of astronomy. Images of observations were originally drawn by hand. In the late 19th century and most of the 20th century, images were made using photographic equipment.
What are the 2 types of astronomy?
Since the 20th century there have been two main types of astronomy, observational and theoretical astronomy. Observational astronomy uses telescopes and cameras to observe or look at stars, galaxies and other astronomical objects.
What are the 4 main types of tools astronomers currently use?
Instruments Used by Astronomers
- Optical Telescopes. The now-indispensable optical telescope instrument was pioneered by Galileo Galilei in 1609, although others had created similar tools by then.
- Radio Telescopes.
- Spectroscopes.
- Star Charts.

Who is the first person to study astronomy?
Galileo was also interested in astronomy. He built a telescope to help him study the sky. Galileo first discovered that the Moon had mountains just like Earth. He also discovered 4 of Jupiter’s moons.

How did the moon get its name?
The word moon can be traced to the word mōna, an Old English word from medieval times. Mōna shares its origins with the Latin words metri, which means to measure, and mensis, which means month. So, we see that the moon is called the moon because it is used to measure the months.
Could life exist on the moon?
The moon may have more water and oxygen than Earth and an oxygen exosphere. Thought to have a subsurface liquid water ocean due to tidal heating or geothermal activity. Free molecular hydrogen (H2) has been detected, providing another potential energy source for life.
