Astronomers Discover Rare Galaxy at Dawn of Time. UC Riverside. The galaxy’s light took 1. Credit: NASA/JPL- Caltech/STSc. I/University of Tokyo. RIVERSIDE, Calif. The researchers made the discovery using NASA’s Spitzer and Hubble space telescopes. The blob- shaped galaxy, called GN- 1. The galaxy, which was discovered and confirmed using ground- based telescopes, is 1. Data from Spitzer and Hubble were used to measure the galaxy’s high star production rate, equivalent to about 1. For reference, our Milky Way galaxy is about five times larger and 1. The 2015 US News ranking for the UCR ECE. Electrical and Computer Engineering. Urmee Khan, University of California at Riverside.

The discovery is surprising because previous surveys had not found galaxies this bright so early in the history of the universe. According to the researchers, GN- 1. The international team of astronomers, led by Masami Ouchi of the University of Tokyo, Japan, first identified the remote galaxy after scanning a large patch of sky with the Subaru Telescope atop Mauna Kea in Hawaii. Its great distance was then carefully confirmed with the W. M. Keck Observatory, also on Mauna Kea. GN- 1. 08. 03. 6 lies near the very beginning of time itself, a mere 7. Big Bang.” Its light has taken 1. Astronomers refer to the object’s distance by a number called its “redshift,” which relates to how much its light has stretched to longer, redder wavelengths due to the expansion of the universe. Objects with larger redshifts are farther away and are seen further back in time. GN- 1. 08. 03. 6 has a redshift of 7. Only a handful of galaxies have confirmed redshifts greater than 7, and only two of these have been reported to be more distant than GN- 1. Infrared observations from Spitzer and Hubble were crucial for measuring the galaxy’s star- formation activity. Astronomers were surprised to see such a large burst of star formation because the galaxy is so small and from such an early cosmic era. Back when galaxies were first forming, in the first few hundreds of millions of years after the Big Bang, they were much smaller than they are today, having yet to bulk up in mass. During this epoch, as the universe expanded and cooled after its explosive start, hydrogen atoms permeating the cosmos formed a thick fog that was opaque to ultraviolet light. This period, before the first stars and galaxies had formed and illuminated the universe, is referred to as the “dark ages.” The era came to an end when light from the earliest galaxies burned through, or “ionized,” the opaque gas, causing it to become transparent.
