NASA | Hubble & Galaxy Evolution

The video discusses the impact of the Hubble Space Telescope on astronomy, highlighting its ability to act as a time machine by observing distant galaxies and providing insights into the universe's history. It explains how Hubble's crisp images help study galaxy evolution and measure galaxy colors to understand star types and ages. The concept of redshift is explored, including the Doppler effect and the universe's expansion. The video emphasizes the importance of studying cosmic history to understand our origins and the potential future of our galaxy.

In what ways can studying the history of galaxies inform us about our own galaxy's past and future?

What are some of the fundamental questions about cosmic origins that scientists are trying to answer?
