What’s out there? Do we know anything about distant galaxies? Join Dr. Elizabeth J. (Betsy) Barton, University of California, Irvine, for “The Search for the Most Distant Galaxies and the End of the Cosmic Dark Ages” discussion @ the Planetarium at CMNH.
The scoop:
The ongoing search for the end of the cosmic dark ages is a quest to detect and understand the first luminous sources that appeared in the Universe. Because they formed in pristine gas made up of only the lightest elements, they are almost certainly very different from the galaxies that exist today.
In addition, the expansion of the Universe has redshifted all of their light into the infrared. Because they are both distant and faint, these galaxies are extremely challenging to detect and to study. As a result, the search for these sources is driven by the development of new techniques and technological breakthroughs in observational astronomy. Dr. Betsy Barton will describe the current status of the search for these “high redshift” galaxies both from the ground and from space.
