Five ‘Instant Packs’ are now available, each focusing on a different astronomy research topic.

30 Junio 2022: An unusual ultra-faint dwarf galaxy has been discovered on the outer fringes of the Andromeda Galaxy thanks to the sharp eyes of an amateur astronomer examining archival data processed by NSF NOIRLab’s Community Science and Data Center. Follow-up by professional astronomers using the International Gemini Observatory, a Program of NSF NOIRLab, revealed that the dwarf galaxy — Pegasus V — contains very few heavier elements and is likely to be a fossil of the first galaxies.

15 Febrero 2022: NOIRLab's Journey Through the Universe — returning with an online program this year — will share the wonders of the Universe and career awareness in science and technology with Hawaiʻi students. In partnership with the Hawaiʻi Department of Education Hilo-Waiakea Complex Area, this year’s implementation of the flagship astronomy outreach program consists of a week of virtual programming along with a new cultural exchange program between classrooms in NOIRLab’s host cities in Hawaiʻi, Chile, and Arizona.

3 Febrero 2022: At a press conference today, NSF NOIRLab announced that it has been selected, along with the SKA Observatory (SKAO), by the International Astronomical Union to host the new IAU Centre for the Protection of the Dark and Quiet Sky from Satellite Constellation Interference. The center coordinates collaborative multidisciplinary international efforts with institutions and individuals and works across multiple geographic areas to help mitigate the negative impact of satellite constellations on ground-based optical and radio astronomy observations as well as humanity’s enjoyment of the night sky.

22 Diciembre 2021: Using observations and archival data from several of NSF 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 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.

31 Agosto 2021: A spectacular portrait of the galaxy Centaurus A has been captured by astronomers using the Dark Energy Camera mounted on the Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory in Chile. This galaxy’s peculiar appearance — cloaked in dark tendrils of dust — stems from a past interaction with another galaxy, and its size and proximity to Earth make it one of the best-studied giant galaxies in the night sky.

25 Agosto 2021: An expansive, multi-year collaboration will create new software to analyze the datasets from the upcoming Rubin Observatory Legacy Survey of Space and Time. The effort, led by Carnegie Mellon University and the University of Washington, will enable large-scale science fueled by the new data. The Community Science and Data Center at NSF NOIRLab will collaborate with the team to make the software freely available to the entire astrophysics community.

23 Agosto 2021: Using the powerful 570-megapixel Dark Energy Camera (DECam) in Chile, astronomers just ten days ago discovered an asteroid with the shortest orbital period of any known asteroid in the Solar System. The orbit of the approximately 1-kilometer-diameter asteroid takes it as close as 20 million kilometers (12 million miles or 0.13 au), from the Sun every 113 days. Asteroid 2021 PH27, revealed in images acquired during twilight, also has the smallest mean distance (semi-major axis) of any known asteroid in our Solar System — only Mercury has a shorter period and smaller semi-major axis. The asteroid is so close to the Sun’s massive gravitational field, it experiences the largest general relativistic effects of any known Solar System object.

25 Junio 2021: A giant comet from the outskirts of our Solar System has been discovered in 6 years of data from the Dark Energy Survey. Comet Bernardinelli-Bernstein is estimated to be about 1000 times more massive than a typical comet, making it arguably the largest comet discovered in modern times. It has an extremely elongated orbit, journeying inward from the distant Oort Cloud over millions of years. It is the most distant comet to be discovered on its incoming path, giving us years to watch it evolve as it approaches the Sun, though it's not predicted to become a naked-eye spectacle.

27 Mayo 2021: In 29 new scientific papers, the Dark Energy Survey examines the largest-ever maps of galaxy distribution and shapes, extending more than 7 billion light-years across the Universe. The extraordinarily precise analysis, which includes data from the survey’s first three years, contributes to the most powerful test of the current best model of the Universe, the standard cosmological model. However, hints remain from earlier DES data and other experiments that matter in the Universe today is a few percent less clumpy than predicted.

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.
