Q: 7) The H-alpha line from a star is observed to be 850 nm. Estimate its redshift
A:
- Binary systems are two astronomical bodies that orbit each other around a common center of mass. If one of the stars in a binary system is super massive it could end up becoming a black hole.
- When supermassive stars run out of fuel for fusion they collapse under their own gravity. This gravitational collapse is so large that nothing escapes the collapsed star and a black hole is created.

- 4. Black holes are theorized to form from (HS-ESS1-3) a. very massive planets that collide with very large stars, resulting in an excessive amount of matter This matter collapses onto itself, extinguishing the star and resulting in the black hole b. very massive stars when their core nuclear fuel has essentially expired, resulting in the core collapsing in on itself. This is due to gravitational forces that act without nuclear fusion counteracting them C. very small stars when their outer shell nuclear fuel expires, leaving the dense core to collapse in on itself. This results in massive gravitational forces d. very young stars that do not have enough nuclear fuel to start the massive chain reactions normally produced in stars emitting large amounts of electromagnetic energy 5. What evidence helps supports the idea of the Big Bang Thoery (HS-ESS1-2) a. Earth Soil Samples b. Neil DeGrass Tyson c. Apparent motion of planets d.
