Astronomy question:
Answer correctly and read the questions corretly, this is all one quesiton if done correclty and organized I will write a very nice review about you!
1. How did Edwin Hubble measure the distance to the Andromeda Galaxy?
He deduced it from its redshift.
He measured its parallax.
He used Cepheid variables in the Andromeda Galaxy.
He used white dwarf supernovae in the Andromeda Galaxy.
State the definition for a parsec, and derive its value in terms of As- tronomical Units. Convert your answer for the value of the distance of a parsec in Astronomical Units into light years. Be sure to include a large and clearly labeled diagram showing how you arrived at your conclusions. Be sure to show all work!
Please Explain
The hotness of stars goes up to millions of degrees Celsius. The coldness of gases can go as low as -273.15 o C. How do you explain the absence of symmetry between hot and cold? Is it possible that there is also a limit to the hotness of any object in the universe? Show your step-by-step solutions.
