By engaging with all the videos within this series, you will effectively complete a full undergraduate course in astronomy, equipping yourself with the knowledge and skills necessary to navigate the night sky with confidence, learning all the basics and many advanced topics! Let’s explore galactic evolution and the vast history of the universe. Building on our understanding of galaxy clustering, we’ll delve deeper into Big Bang cosmology. We’ll observe how galaxies evolve from small misshapen objects to magnificent spirals and giant ellipticals. The cosmological principle states that our location in the universe isn’t special, and the laws of physics are the same everywhere. Far-out surveys allow us to look back in time and observe galaxies billions of years ago. Galaxies grow from small, blue, irregular shapes into larger forms through mergers. Large-scale surveys like the 2DF Galaxy Redshift Surveys and the Sloan Digital Sky Survey have cataloged millions of galaxies and mapped their distribution, advancing our understanding of galactic structure and evolution. The Hubble Space Telescope has provided deep views into the universe, revealing the history of galaxies. The Hubble Deep Field and Hubble Ultra Deep Field images show galaxies back to nearly 13 billion light years, capturing them in varying stages of evolution. The Hubble Ultra Deep Field pushed the boundaries, revealing 10,000 galaxies in one image and providing a glimpse into the universe when it was only 800 million years old. I’ll illustrate how ancient galaxies differ from today’s, emphasizing galactic evolution. We’ll explore photometric redshift, a technique to measure galaxy distances based on light characteristics. It helps identify high-redshift objects and reveals the universe’s early history. Ultra-distant galaxies with redshifts of 10 or more existed when the universe was just a few hundred million years old. These findings provide crucial insights into galaxy formation. Finally, I’ll discuss how these observations fit into the Big Bang theory and predict galactic evolution. We don’t see Milky Way-type galaxies in the deep past, showing significant galaxy evolution over billions of years. This is part of my complete intro Astronomy class that I taught at Willam Paterson University and CUNY Hunter. This is a remaster of a 2018 video, and there are some things from before the launch of JWST.
