What is stellar and galactic astronomy?
The study of the sun and stars, their physical properties and evolution, interstellar matter, star clusters, our galaxy and other galaxies, the origin and evolution of the universe.
What is extragalactic space?
An extragalactic planet, also known as an extragalactic exoplanet or an extroplanet, is a star-bound planet or rogue planet located outside of the Milky Way Galaxy. This means that even galactic planets located farther than that distance have not been detected.

Why is extragalactic astronomy important?
It is through extragalactic astronomy that astronomers and physicists are able to study the effects of General Relativity such as gravitational lensing and gravitational waves, that are otherwise impossible (or nearly impossible) to study on a galactic scale.
Who is the founder of extragalactic astronomy?
Edwin Hubble, in full Edwin Powell Hubble, (born November 20, 1889, Marshfield, Missouri, U.S.—died September 28, 1953, San Marino, California), American astronomer who played a crucial role in establishing the field of extragalactic astronomy and is generally regarded as the leading observational cosmologist of the …
What are the 2 main branches of astronomy?
Branches of astronomy

Can astronomers work for NASA?
There are only a few thousand professional astronomers in the U.S. Many are professors at colleges and universities. They teach astronomy courses and usually do research. Others work at NASA or, like me, with companies that work with NASA, or at the National Observatories. Nearly all professional astronomers have a Ph.
