Ancient astronomers and their contributions
Astronomy is a small community, so you can expect to travel internationally quite often to present your results and collaborate with others in your specific subfield..
Ancient astronomers
The worldwide com- munity of professional astronomers is only about 10,000; most are located in the US (with about 1,000 in the UK and 250 in Australia).
Under the heading of “astronomy” there are many fields (and sub-fields) of research..

Do astronomers travel to space?
Astronomers, unlike astronauts, do not go into space.
Astronomers are the people who observe objects in space from the safety of Earth.
Instead of reaching outer space through rockets, astronomers use their handy telescopes to gaze at the thousands of different objects in the sky..
Early astronomers
Telescopes use lenses or mirrors to collect and focus waves from the electromagnetic spectrum, including visible light, allowing us to look at celestial objects.
By studying the electromagnetic waves given off by objects such as stars, galaxies, and black holes, astronomers can better understand the universe..
Famous astronomers alive
How many people are currently employed as an Physicists and Astronomers in the United States? There are approximately 19500 people employed as a Physicists and Astronomers..
How far have we explored the universe?
So far, humans have only explored to just past the edge of own solar system with space craft and probes.
Scientists have used telescopes to observe much farther into space.
However, the percent of known space that humans have observed with telescopes and other instruments is difficult to estimate..
How long have astronomers been around?
The first documented records of systematic astronomical observations date back to the Assyro-Babylonians around 1000 BCE.
From this cradle of civilisation in Mesopotamia – in the southern part of present-day Iraq – astronomers had built up knowledge of the celestial bodies and recorded their periodic motions..

Galileo Galilei (1564-1642)
Possibly the world's best-known astronomer, Galileo constructed a simple refracting telescope in 1610 and became the first person to use a spy-glass for astronomy.
The sheer number of stars, the rough surface of the Moon and sunspots astonished him.Jul 12, 2023.
How many people work as an astronomer?
Despite the allure of exploring the vastness of space, the profession of an astronomer remains relatively rare.
According to the Bureau of Labor Statistics, as of 2020, there were only around 2,000 astronomers employed in the United States..
Is astronomer a rare job?
What are the best countries to study Physics and Astronomy abroad? The best countries to study Physics and Astronomy abroad are Japan, Germany, Russia, Finland, Belgium, the United States of America, Canada, and the United Kingdom..
Top 10 observatories in the world
Those who become astronomers usually have a broad background in maths, sciences and computing in high school.
Taking courses that teach how to research, write, and present papers are also invaluable.
In college/university most astronomers get a PhD in astronomy or physics..
Types of astronomy
Without astronomy, advances in x-ray imaging for the medical industry wouldn't have happened.
This includes many devices such as breast cancer, osteoporosis, heart disease, and dental x-rays.
The development of the charge-coupled device, CCDs, helped reduce exposure to x-rays..
What do astronomers do for the world?
Astronomers study planets, stars, and other celestial bodies.
They use ground-based equipment, such as optical telescopes, and space-based equipment, such as the Hubble Space Telescope.
Some astronomers study distant galaxies and phenomena such as black holes and neutron stars..
What is the distance of astronomers?
Astronomical units, abbreviated AU, are a useful unit of measure within our solar system.
One AU is the distance from the Sun to Earth's orbit, which is about 93 million miles (150 million kilometers)..
When did astronomers start?
The first documented records of systematic astronomical observations date back to the Assyro-Babylonians around 1000 BCE.
From this cradle of civilisation in Mesopotamia – in the southern part of present-day Iraq – astronomers had built up knowledge of the celestial bodies and recorded their periodic motions..
Where are astronomers found?
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..

Why does the world need astronomers?
By studying the cosmos beyond our own planet, we can understand where we came from, where we are going, and how physics works under conditions which are impossible to recreate on Earth.
In astronomy, the Universe is our laboratory.
Why is astronomy so popular?
And that is what astronomy can provide: a way of looking at the universe that allows you to have the proper perspective.
You can gain a sense of scale, a sense of motion and a sense of regularity in an otherwise chaotic and unpredictable universe.
Astronomy isn't just relevant, it's essential to freedom.Jan 7, 2021.
- The observable universe does.
It's 46 billion light years away in any direction, and the whole universe has a temporal edge, or what we call a beginning, but almost certainly not a spatial one.
Does the universe have a center?
