Step by step
Solved in 2 steps
- Explain why massive stars evolve faster?Which of the following is not correct regarding Cepheid variable stars. They can be measure out to ~ 80 Million light years Once the period is measured, the luminosity is known Early 1900s astronomers used them to map out our galaxy more accurately. All of them have about the same luminosity; knowing their apparent magnitude allows us to calculate the distance.Was the Big Bang an explosion? Explain your answer.
