Beyond the riot of stars visible on a clear night, beyond more distant galaxies studied over the past half century, are some of the earliest galaxies, created during the early formation of the Universe. Thanks to powerful 21st-century telescopes, astronomers can now study these distant galaxies dating back 12-13 billion years.
Arianna Long, UW assistant professor of astronomy, is particularly interested in massive and extreme early galaxies, which are 10 to 100 times larger than the Milky Way but often cramped into spaces 10 times smaller. She believes these early galaxies may provide clues to how the Universe evolved.
