Astronomers have uncovered evidence for a vast collection of young galaxies 12 billion light years away. The newly discovered “proto-cluster” of galaxies, observed when the universe was only 1.7 billion years old (12% of its present age), is one of the most massive structures known at that distance. The discovery was made using telescopes at KPNO and Keck Observatory. NOAO Astronomer Arjun Dey is the lead author of the study.

Kitt Peak National Observatory (KPNO), part of the National Optical Astronomy Observatory (NOAO), supports the most diverse collection of astronomical observatories on Earth for nighttime optical and infrared astronomy and daytime study of the Sun. Sharing the mountaintop site with the National Solar Observatory, KPNO, founded in 1958, operates three major nighttime telescopes and hosts the facilities of consortia which operate 22 optical telescopes and two radio telescopes. (See the Tenant Observatories list.) Kitt Peak is located 56 miles southwest of Tucson, AZ, in the Schuk Toak District on the Tohono O'odham Nation and has a Visitor Center open daily to the public.

If you need to contact someone at NOAO but are uncertain of that person's email address, simply send email to "first_inital_last_name_at_noao.edu", i.e., bsmith_at_noao.edu or jdoe_at_noao.edu. A general purpose email account has been set up to answer any questions you have about observing at Kitt Peak and don't know who to ask. Any and all questions you have can be e-mailed to this address: kpno_at_noao.edu and it will be forwarded to the appropriate person.
