Astronomers study planets, stars, galaxies, and other celestial bodies.
What is an example of a astronomers?
Galileo Galilei is an example of an early observational astronomer who used a telescope and recorded his findings. Tools that modern observational astronomers use to study space include radio waves, cameras, infrared technologies, ultraviolet wavelengths, x-rays and gamma rays.
What do scientists in astronomy study?
Astronomy is the study of everything in the universe beyond Earth’s atmosphere. That includes objects we can see with our naked eyes, like the Sun , the Moon , the planets, and the stars . It also includes objects we can only see with telescopes or other instruments, like faraway galaxies and tiny particles.
How many astronomers are there?
As science professions go, astronomy is a relatively small field, with about 6,000 professional astronomers in North America. Because of its size, astronomers get to know and collaborate with many colleagues across the U.S. and around the world.
What do observational astronomers do?
Observational astronomers use telescopes to study the properties of things like the Big Bang and interpret those observations, using their knowledge of physics, to help us further understand the properties and evolution of the Big Bang.

What are the 2 types of astronomy?
In the past century or so, astronomy has been broadly split into two camps — observational astronomy (using telescopes and cameras to collect data about the night sky) and theoretical astronomy (using that data to analyze, model and theorize about how objects and phenomena work).
Who called astronomers?
A scientist who studies the objects in the sky, including planets, galaxies, black holes, and stars, is called an astronomer. These days, the terms astronomer and astrophysicist are used interchangeably, to talk about any physicist who specializes in celestial bodies and the forces that affect them.
What tools do astronomers 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.
Where do astronomers work?
Astronomer work environment
Work environments for astronomers vary. They can be employed as professors or research staff at universities, while others may work in government-supported observatories and labs. Some work for private companies, such as aerospace firms.
Who are the first astronomers?
The Ancient Greeks developed astronomy, which they treated as a branch of mathematics, to a highly sophisticated level. The first geometrical, three-dimensional models to explain the apparent motion of the planets were developed in the 4th century BC by Eudoxus of Cnidus and Callippus of Cyzicus.

What are the working conditions of an astronomer?
Most astronomers work in offices and occasionally visit observatories, buildings that house ground-based telescopes used to observe natural phenomenon and gather data. Some astronomers work full time in observatories.
What are the divisions of observational astronomy?
High-energy astronomy includes X-ray astronomy, gamma-ray astronomy, and extreme UV astronomy. Occultation astronomy is the observation of the instant one celestial object occults or eclipses another. Multi-chord asteroid occultation observations measure the profile of the asteroid to the kilometre level.
What astronomers do all day?
On a daily basis, Astronomers analyze research data to determine its significance, using computers. They study celestial phenomena, using a variety of ground-based and space-borne telescopes and scientific instruments. Develop theories based on personal observations or on observations and theories of other astronomers.
