What do astronomers do?

Answer 1

Astronomers use the principles of physics, chemistry, and mathematics to learn about the fundamental nature of the universe, including the sun, moon, planets, stars, and galaxies. As such, astronomy is sometimes considered a subfield of physics. They also apply their knowledge to solve problems in navigation, space flight, and satellite communications and to develop the instrumentation and techniques used to observe and collect astronomical data.

Almost all astronomers do research. Most of them also have teaching as part of their work, usually in a university.

Some are theoreticians, working on the laws governing the structure and evolution of astronomical objects. Others analyze large quantities of data gathered by observatories and satellites and write scientific papers or reports on their findings. Some astronomers actually operate large space-based or ground-based telescopes, usually as part of a team. However, astronomers may spend only a few weeks each year making observations with optical telescopes, radio telescopes, and other instruments.

A small number of astronomers work in museums housing planetariums. These astronomers develop and revise programs presented to the public and may direct planetarium operations.

Work environment. Most astronomers do not encounter unusual hazards in their work. Astronomers who make observations with ground-based telescopes may spend many hours working in observatories. This work usually involves travel to remote locations and may require working at night. Astronomers whose work depends on grant money may spend a lot of time writing grant proposals to keep their work funded.

Astronomers may need to work at odd hours to observe celestial phenomena, particularly those working with ground-based telescopes.

Answer 2

They study how the universe works such as the stars, galaxy and etc..

Answer 3

an astromomer dose nothing but do scientific work

Answer 4

Looks at star and planets and plots them on star maps and stuff
