Astronomers are always seeking to build bigger, more powerful telescopes, which will allow them to study faint galaxies that are very far away. Which of the following is the main reason they're so obsessed with studying very distant galaxies? Group of answer choices Light traveled much faster during the early history of the universe, so we can study how the speed of light has changed through time. Very distant galaxies are more likely to contain planets than the Milky Way is, so we have a better chance of detecting life in those galaxies than we do in our own galaxy. Since the light from these galaxies took so long to reach us, we're seeing them as they were when the universe was very young. Strangely, distant galaxies are more like our Milky Way than the Milky Way's `neighbor' galaxies are, and astronomers would like to figure out why this is.

Suppose a spectral line from an object in space was shifted from 5007.0 to 5100.0 Angstroms. What can we tell about this object? A) It is a star. B) It is very cold. C) It is blueshifted, hence coming towards us. D) Its radial velocity is positive, meaning it is moving away from us. E) It is a planet in a distant galaxy. F) It is an exoplanet.

A brand new telescope has been named after you. It is therefore only fitting that you get to make the very first set of observations. During your first night observing, you first measure the apparent brightness and spectrum of a group of stars that appear close to each other within the telescopes field of view. From a separate set of observations 6 months later, you are able to measure each star’s parallax. Next you plot the luminosity and temperature of each star in a Hertzsprung-Russell Diagram What features below help you conclude that the group of stars is a star cluster? Explain Approximately how old do you think this star cluster is? Explain How do you expect the spectrum of the most luminous and least luminous main sequence stars in the cluster to differ? Explain why these differences occur in terms of the star’s properties and any measured absorption lines. A year after your discovery, another new star cluster has been found by the same telescope, but its distance is too far…
