Do astrophysics study black holes?
Astronomers believe that supermassive black holes lie at the center of virtually all large galaxies, even our own Milky Way. Astronomers can detect them by watching for their effects on nearby stars and gas….Recent Discoveries.

Can I learn astrophysics on my own?
You can buy a number of excellent books and textbooks, and learn almost anything on your own. But if you want to do so for any reason other than your personal pleasure you would have to enroll in a graduate program at a well-respected university with a top-flight staff of astrophysicists.
What careers study black holes?
Astronomers
Astronomers study the origin and make-up of the universe, including its planets, stars, galaxies and black holes.
What is the importance of black holes in physics?
Black Holes may also be fundamental to properly understanding gravity which is very useful. In fact it is necessary to include corrections from General Relativity (which has been much better understood through the study of Black Holes) to the Global Positioning Satellites in order to make them accurate to more than a few metres.
How do astronomers find supermassive black holes?
Astronomers believe that supermassive black holes lie at the center of virtually all large galaxies, even our own Milky Way. Astronomers can detect them by watching for their effects on nearby stars and gas. This chart shows the relative masses of super-dense cosmic objects.
What happens when a star passes close to a black hole?
A similar process can occur if a normal star passes close to a black hole. In this case, the black hole can tear the star apart as it pulls it toward itself. As the attracted matter accelerates and heats up, it emits x-rays that radiate into space.
How much mass does it take to create a black hole?
If the core’s mass is more than about three times the mass of the Sun, the equations showed, the force of gravity overwhelms all other forces and produces a black hole. A video about black holes.
