Keck Observatory Presents How Stars Destroyed Most of the Atoms in the Universe
W. M. Keck Observatory Presents
How Stars Destroyed Most of the Atoms in the Universe
University of California at
Riverside
The first galaxies had an
extraordinary impact on the young universe. Their ultraviolet light destroyed
nearly all of the atoms in the cosmos. This process, called reionization, had
severe consequences for galaxies trying to form thereafter. Unfortunately, we
have no idea how it happened. In galaxies today ultraviolet light cannot
escape, so the first galaxies must have been very different from those we see
today. Dr. Siana will describe the quest to detect these first galaxies and
their impact on the early universe.
This event also will be webcast live via the Keck
Observatory website.
