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 19 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.

WHIRC image

Grayscale: Ks-band WHIRC image from December 2010 field in OMC 3 containing several protostars, most of which were detected in this mosaic, totaling 1 hour of on-source integration. The SE fit and resulting model image for HOPS93 are shown. The SED of HOPS 93 could be fit with either a dense envelope of infall rate 1 e-4 Msun/yr viewed from close to pole-on, or with a less dense envelope of infall rate 4e-6 viewed through an edge-on disk. The bipolar structure seen in the WHIRC image indicates the latter is correct.
