How many years does it take to study astronomy?

The Honours programme lasts one year and the Masters programme lasts up to two years. It also offers an extended Honours programme for students who have no astronomy background or who need to improve their physics and mathematics proficiency.

Do astronomers make good money?

Q: How much money do astronomers make? A: It’s hard to get rich by being an astronomer, but most astronomers make enough money to live comfortably. The amount astronomers are paid depends on where the astronomer is working, how much experience the astronomer has, and even how prestigious the astronomer is.

What can you learn in astronomy?

Astronomy students study space, the history and future of the universe, and the objects within, such as planets, stars, and galaxies. Subjects of study include the evolution of stars, how the stars and planets move through space, chemistry, and advanced math.

What does an astronomer do?

Astronomers are scientists who study the universe, its objects and how it works. They aim to push the boundaries of human knowledge about how the universe works by observation and theoretical modelling.

Most astronomy positions require a PhD degree, which can take five or six years of graduate work.

Who discovered space first?

Edwin HubbleEdwin Hubble changed the way we thought of the Universe forever. When scientists decided to name the Hubble Space Telescope after him, they could not have made a more appropriate choice.

What are two 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.

Why do we need to study astronomy?

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!

What is basic astronomy?

Astronomy is the scientific study of celestial objects (such as stars, planets, comets, and galaxies) and phenomena that originate outside the Earth’s atmosphere (such as the cosmic background radiation).

Who discovered the first star?

Galileo Galilei, an Italian scientist, lived from 1564 to 1642. In 1610, he was the first person we know of to use the newly invented telescope to look at the stars and planets.

How technology is useful in astronomy?

Thanks to technology, astronomers can now look beyond the electromagnetic spectrum as the only means of studying the compositions of celestial objects, opening a whole new way in which we can study the universe.
