Press Releases: Kitt Peak National Observatory

22 Diciembre 2021: Using observations and archival data from several of NSF's NOIRLab’s observatories, together with observations from telescopes around the world and in orbit, astronomers have discovered at least 70 new free-floating planets — planets that wander through space without a parent star — in a nearby region of the Milky Way. This is the largest sample of such planets found in a single group and it nearly doubles the number known over the entire sky.

5 Noviembre 2021: NSF’s NOIRLab fully supports the scientific vision of Pathways to Discovery in Astronomy and Astrophysics for the 2020s and stands ready, along with our managing organization, AURA, to join our community in advocating for and contributing to the implementation of the survey’s recommendations. NOIRLab along with its partners are honored that the community has ranked the US Extremely Large Telescope Program as the highest ground-based priority in Pathways to Discovery.

18 Agosto 2021: What was once the largest solar observatory in the world is now undergoing a transformation to become a one-of-a-kind facility for sharing the wonders of astronomy with people around the globe. Construction work has started to recast the McMath-Pierce Solar Telescope facility at Kitt Peak National Observatory into the NOIRLab Windows on the Universe Center for Astronomy Outreach.

28 Junio 2021: Some exoplanet searches could be missing nearly half of the Earth-sized planets around other stars. New findings from a team using the international Gemini Observatory and the WIYN 3.5-meter Telescope at Kitt Peak National Observatory suggest that Earth-sized worlds could be lurking undiscovered in binary star systems, hidden in the glare of their parent stars. As roughly half of all stars are in binary systems, this means that astronomers could be missing many Earth-sized worlds.

17 Mayo 2021: A quest to map the Universe and unravel the mysteries of dark energy began officially today, 17 May 2021, at Kitt Peak National Observatory, a Program of NSF’s NOIRLab. Over the next five years, the Dark Energy Spectroscopic Instrument (DESI) will capture the light from tens of millions of galaxies and other cosmic objects. During its four-month trial run, which just concluded, the project already collected millions of observations.

28 Abril 2021: This image of the dwarf galaxy Sextans B, taken with the Nicholas U. Mayall 4-meter Telescope at Kitt Peak National Observatory, a Program of NSF’s NOIRLab, contains a menagerie of astronomical objects, from bright stars in the foreground to distant galaxies hiding in the background. The galaxy itself contains both the cradles and the graves of stars, hosting star-forming regions as well as stellar death shrouds.

16 Marzo 2021: This spectacular image highlights the majestic spiral galaxy Messier 106 and its diminutive neighbors, as well as a dense field of background galaxies and foreground stars. This may be the best view yet of Messier 106 in its entirety, showing both the warped central disk and the tenuous outer reaches of the galaxy.

15 Marzo 2021: AstroDay–Chile’s annual astronomy education festival will take place entirely online in Spanish for the first time in 2021, because of the COVID-19 pandemic. Since 2007, AstroDay has provided unique opportunities for the public to engage with the scientists and staff who work at the most important observatories in Chile. This year’s event takes place from 17 to 19 March 2021 and all activities are free to engage with online.

22 Febrero 2021: Journey Through the Universe — which, owing to the COVID-19 pandemic, will take place entirely online for the first time in 2021 — will share the wonders of the Universe and the possibilities of a career in science and technology with school students on Hawai‘i Island. This year’s iteration of the flagship astronomy education and outreach program is highlighted by a week of virtual educational programming from 1 to 5 March 2021.

13 Enero 2021: Astronomers have curated the most complete list of nearby brown dwarfs to date thanks to discoveries made by thousands of volunteers participating in the Backyard Worlds citizen science project. The list and 3D map of 525 brown dwarfs — including 38 reported for the first time — incorporate observations from a host of astronomical instruments including several NOIRLab facilities. The results confirm that the Sun’s neighborhood appears surprisingly diverse relative to other parts of the Milky Way Galaxy.

13 Enero 2021: Data from the DESI (Dark Energy Spectroscopic Instrument) Legacy Imaging Surveys have revealed over 1200 new gravitational lenses, approximately doubling the number of known lenses. Discovered using machine learning trained on real data, these warped and stretched images of distant galaxies provide astronomers with a flood of new targets with which to measure fundamental properties of the Universe such as the Hubble constant, which describes the expanding Universe.

13 Enero 2021: Astronomers using images from Kitt Peak National Observatory and Cerro Tololo Inter-American Observatory have created the largest ever map of the sky, comprising over a billion galaxies. The ninth and final data release from the ambitious DESI Legacy Imaging Surveys sets the stage for a ground-breaking 5-year survey with the Dark Energy Spectroscopic Instrument (DESI), which aims to provide new insights into the nature of dark energy. The map was released today at the January 2021 meeting of the American Astronomical Society.

5 Enero 2021: A stunning long-exposure observation from the Kitt Peak National Observatory reveals the spiral galaxy NGC 1003 in glorious detail. The deep observation also shows a treasure trove of background galaxies spread throughout the image.

12 Octubre 2020: NOIRLab is pleased to announce that limited science operations are being re-established at Kitt Peak National Observatory in Arizona and at the Cerro Tololo Inter-American Observatory, Gemini South, and SOAR facilities in Chile after suspension on 18 March 2020 due to the COVID-19 pandemic.

22 Septiembre 2020: Big Astronomy or Astronomia a Gran Escala is a bilingual planetarium show that extends beyond the dome using web-based and hands-on resources. In Big Astronomy, discover Chile’s grand observatories and meet the people who push the limits of technology and expand what we know about the Universe using world-class telescopes.

25 Agosto 2020: A report by experts representing the global astronomical community, concludes that large constellations of bright satellites in low Earth orbit will fundamentally change ground-based optical and infrared astronomy and could impact the appearance of the night sky for stargazers worldwide. The report is the outcome of the recent SATCON1 virtual workshop, which brought together more than 250 scientists, engineers, satellite operators, and other stakeholders.

18 Agosto 2020: How complete is our census of the Sun’s closest neighbors? Astronomers using NSF’s NOIRLab facilities and a team of data-sleuthing volunteers participating in Backyard Worlds: Planet 9, a citizen science project, have discovered roughly 100 cool worlds near the Sun — objects more massive than planets but lighter than stars, known as brown dwarfs. Several of these newly discovered worlds are among the very coolest known, with a few approaching the temperature of Earth — cool enough to harbor water clouds.

4 Agosto 2020: New detailed observations with NSF’s NOIRLab facilities reveal a young exoplanet, orbiting a young star in the Hyades cluster, that is unusually dense for its size and age. Weighing in at 25 Earth-masses, and slightly smaller than Neptune, this exoplanet’s existence is at odds with the predictions of leading planet formation theories.

2 Julio 2020: This archival image from the Nicholas U. Mayall 4-meter Telescope at Kitt Peak National Observatory, a Program of NSF’s NOIRLab, captures a snapshot of some cosmic pyrotechnics — the asymmetric spiral arms of the galaxy NGC 925, which host dazzling bursts of star formation. This stunning image is only one example of the spectacular firework displays that astronomy has to offer.

18 Junio 2020: This striking image from NOIRLab’s Kitt Peak National Observatory (KPNO) presents a portrait of the irregular galaxy IC 10, a disorderly starburst galaxy close to the Milky Way. As well as a population of bright young stars, this irregular galaxy harbors exotic Wolf-Rayet stars and a black hole.
