Announcement: Kitt Peak National Observatory

21 November 2024: For four years the NEID (rhymes with fluid) spectrograph, mounted on the WIYN 3.5-meter Telescope at U.S. National Science Foundation Kitt Peak National Observatory (KPNO), a Program of NSF NOIRLab, has been delivering on one of its main science goals — to confirm exoplanet candidates from other exoplanet missions and characterize both newly confirmed and known planets. But NEID is also carrying out a larger program called the NEID Earth Twin Survey (NETS). NETS is aimed at pushing exoplanet detection beyond the limits of pre-NEID instruments with the specific goal of searching around bright, nearby stars for low-mass exoplanets that weren’t detectable before. NEID is now delivering on this goal as the first instrument to confirm and characterize exoplanet HD 86728 b. The team, led by postdoctoral researcher and NOIRLab astronomer Arvind Gupta, presents these results in a paper to appear in AAS Journals. NEID is optimized to observe an …

26 July 2024: Kitt Peak National Observatory will host a Perseid meteor shower watch party on 11–12 August, from 7 p.m. to midnight. Stand amongst the world-class telescopes that astronomers use to discover our Universe while fiery pieces of cosmic dust streak across the night sky. The Perseids are widely regarded as the most consistent and amazing meteor shower to grace our skies each year. The shower is associated with comet Swift-Tuttle and can produce displays of up to 100 ‘shooting stars’ per hour. And what better location to watch the show than from high in the Quinlan mountains on the Tohono O’odham Nation, beneath the clear skies of the Sonoran Desert? This experience will include a light dinner, after which, weather permitting, there will be guided stargazing, and views of stars, galaxies and more through our Visitor Center 0.5-meter telescope, and also an open area to view the meteor shower with members …

In all, seven audiovisual ambassadors, ten social media ambassadors, two music ambassadors, 13 education ambassadors, one dark skies ambassador and two art ambassadors were …

26 January 2024: We are sorry to pass on the sad news that John Jefferies, former Director of the National Optical Astronomy Observatory (NOAO, now NSF’s NOIRLab), passed away on the evening of 18 January. He was 98. Jefferies served as NOAO’s first Director beginning in 1984 when Kitt Peak National Observatory (KPNO) and the Cerro Tololo Inter-American Observatory (CTIO) were united into one entity, serving until 1987. Jefferies’ astronomy roots were in solar physics beginning in his native Australia: specifically in developing the physical understanding of solar flares and radio bursts. After a highly productive research career spent both in Australia and various institutions in the continental US, Jefferies went to the University of Hawai‘i in 1964 to start a solar physics program. At that time, Jefferies also submitted a proposal to NASA on behalf of the University of Hawai‘i to build and operate a telescope to support planetary research. After winning …

2 October 2023: Scientists, including astronomers from the International Astronomical Union Centre for the Protection of the Dark and Quiet Sky from Satellite Constellation Interference (IAU CPS), have published a paper in Nature assessing the detailed impact of the BlueWalker 3 satellite on astronomy. Building on initial observations from shortly after its launch, these new results complement the initial understanding of this unusual satellite and the paper contains details of how the satellite’s brightness changes over time and the visibility of jettisoned hardware. With companies intending to deploy more commercial satellites in the coming years, this paper highlights the need for pre-launch impact assessments. “The interference of satellites in astronomy has become an increasingly pressing issue over the last few years,” commented first author Sangeetha Nandakumar from the Instituto de Astronomía y Ciencias Planetarias, Universidad de Atacama Chile. BlueWalker 3 was launched into low Earth orbit on 10 September 2022 by AST SpaceMobile …

5 September 2023: SatCons 101, a new educational curriculum for learning about the design of large satellite constellations and their impact on astronomy, has been launched by the International Astronomical Union’s (IAU) Centre for the Protection of the Dark and Quiet Sky from Satellite Constellation Interference (CPS), co-hosted by the NSF’s NOIRLab and the SKA Observatory (SKAO) on behalf of the International Astronomical Union (IAU). While satellite constellations unquestionably bring social benefits, such as broadband communication and Global Position Systems (GPS), they can also have negative impacts on astronomy and the environment. To educate interested parties about these issues, SatCons 101 presents eight video modules designed to teach the fundamentals of satellite constellations. Topics covered are their design, their purpose, their impact on optical/infrared and radio astronomy, and international regulations on their use of space. The curriculum is designed to be unbiased, presenting participants with data and facts that will help bring awareness …
