How do you break into astronomy?

Here are the steps:

What are the 4 types of astronomy?

Astronomy degrees typically last three or four years at undergraduate level and one or two years at master's level, depending on the location..

What do astronomers use when they are studying astronomy?

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 most effective way to measure distances to distant galaxies?

For more-distant galaxies, astronomers rely on the exploding stars known as supernovae.
Like Cepheids, the rate at which a certain class of supernovae brighten and fade reveals their true brightness, which then can be used to calculate their distance..

What tool are astronomers using to study the universe?

Space telescope – Instrument in space to study astronomical objects.
Spectrometers – Used to measure spectral components of light.
Sundial – Device that tells the time of day by the apparent position of the Sun in the sky.
Telescope – Instrument that makes distant objects appear magnified..
