19 November 2024: Researchers have used the Dark Energy Spectroscopic Instrument (DESI) to map nearly six million galaxies across 11 billion years of cosmic history, allowing them to study how galaxies clustered throughout time and investigate the growth of the cosmic structure. This complex analysis of DESI’s first-year data provides one of the most stringent tests yet of Einstein’s general theory of relativity.

4 November 2024: Using data from NASA's JWST and Chandra X-ray Observatory, a team of astronomers have discovered a supermassive black hole at the center of a galaxy just 1.5 billion years after the Big Bang that is consuming matter at a phenomenal rate — over 40 times the theoretical limit. While short lived, this black hole’s ‘feast’ could help astronomers explain how supermassive black holes grew so quickly in the early Universe.

21 October 2024: 100 years ago Edwin Hubble discovered decisive evidence that other galaxies existed far beyond the Milky Way. This image, captured by the Gemini North telescope, one half of the International Gemini Observatory, features a portion of the enormous Perseus Cluster, showcasing its ‘island Universes’ in awe-inspiring detail. Observations of these objects continue to shed light not only on their individual characteristics, but also on cosmic mysteries such as dark matter.

11 October 2024: NSF–DOE Vera C. Rubin Observatory celebrated a landmark moment in astronomy and astrophysics with the dedication of the Simonyi Survey Telescope on 4 October 2024. With the Simonyi family as guests of honor, Rubin Observatory recognized the pivotal role of Charles and Lisa Simonyi’s philanthropy in advancing construction of the Observatory and supporting research that will soon transform our understanding of the Universe.

1 October 2024: Cradled within the fiery petals of the Rosette Nebula is NGC 2244, the young star cluster which it nurtured. The cluster’s stars light up the nebula in vibrant hues of red, gold and purple, and opaque towers of dust rise from the billowing clouds around its excavated core. This image, captured by the 570-megapixel Dark Energy Camera, is being released in celebration of NOIRLab’s fifth anniversary.

27 September 2024: Today Kitt Peak Visitor Center celebrated 60 years of greeting visitors to the U.S. National Science Foundation Kitt Peak National Observatory. Since opening in 1964, the Visitor Center has welcomed more than two million guests to the mountain in its mission to inspire a sense of wonder and awe about the Universe through exhibits, daytime tours and nighttime public programs.

23 September 2024: Observations using the Dark Energy Camera (DECam) confirm astronomers’ expectation that early-Universe quasars formed in regions of space densely populated with companion galaxies. DECam’s exceptionally wide field of view and special filters played a crucial role in reaching this conclusion, and the observations reveal why previous studies seeking to characterize the density of early-Universe quasar neighborhoods have yielded conflicting results.

12 September 2024: Photons, neutrinos, cosmic rays and gravitational waves all carry information about the Universe. Multi-messenger astronomy brings together these four signals to investigate astronomical events from multiple cosmic perspectives. With its sensitive camera and suite of filters, NSF–DOE Vera C. Rubin Observatory will increase the population of known multi-messenger sources by obtaining crucial color information and localizing events for follow-up observations by other telescopes.

14 August 2024: The Dark Energy Camera captures an image of the dazzling Coma Cluster, named after the hair of Queen Berenice II of Egypt. Not only significant in Greek mythology, this collection of galaxies was also fundamental to the discovery of the existence of dark matter. The theory emerged in 1937 when Swiss astronomer Fritz Zwicky noticed that the Coma Cluster galaxies behaved as if they were under the influence of vast amounts of unobservable ‘dark’ matter.

1 August 2024: Vera C. Rubin Observatory’s 3.5-meter secondary mirror has been installed on the Simonyi Survey Telescope on Cerro Pachón in Chile. The glass mirror — made by Corning Advanced Optics and polished by L3Harris Technologies — is the first permanent component of the telescope’s state-of-the-art, wide-field optical system to be installed and will soon contribute to a better understanding of our Universe.

17 July 2024: Using the WIYN 3.5-meter telescope at the U.S. National Science Foundation Kitt Peak National Observatory, a Program of NSF NOIRLab, astronomers have discovered the extreme orbit of an exoplanet that’s on its way to becoming a hot Jupiter. This exoplanet not only follows one of the most drastically stretched-out orbits of all known transiting exoplanets but is also orbiting its star backwards, lending insight into the mystery of how hot Jupiters evolve.

15 July 2024: Too big to be planets but too small to be stars, distant brown dwarfs are a key ingredient for understanding the history of the Milky Way. Vera C. Rubin Observatory’s Legacy Survey of Space and Time will detect a population of ancient brown dwarfs about 20 times bigger than we’ve previously seen, revealing the processes that shaped our home galaxy.

25 June 2024: A festive array of bright pinks and blues makes for a remarkable sight in this image captured with the Gemini North telescope, one half of the International Gemini Observatory. Resembling a cloud of cosmic confetti, this image is being released in celebration of Gemini North’s 25th anniversary. NGC 4449 is a prime example of starburst activity caused by the interacting and mingling of galaxies as it slowly absorbs its smaller galactic neighbors.

17 June 2024: With the help of the powerful GNIRS instrument on the Gemini North telescope, one half of the International Gemini Observatory, supported in part by the U.S. National Science Foundation and operated by NSF NOIRLab, a team of astronomers have discovered a double-record-breaking pair of quasars. Not only are they the most distant pair of merging quasars ever found, but also the only pair confirmed in the bygone era of the Universe’s earliest formation.

28 May 2024: More than 70 NOIRLab staff volunteers welcomed hundreds of visitors from the Tohono O’odham Nation to Kitt Peak National Observatory to enjoy a night of telescope viewings, cultural performances, and educational activities.

22 May 2024: The largest camera ever built for astrophysics has completed the long journey from SLAC National Accelerator Laboratory in California to the summit of Cerro Pachón in Chile, where it will soon help unlock the mysteries of the Universe.

6 May 2024: The dark, dusty cometary globule known as CG 4 is spotlighted in this image from the Department of Energy-fabricated Dark Energy Camera mounted on the U.S. National Science Foundation Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory, a Program of NSF NOIRLab. How these hard-to-detect clouds get their distinctive structure is still unclear, but astronomers speculate that it’s a consequence of the hot, massive stars that surround them.

30 April 2024: With its shiny, new silver coating, Vera C. Rubin Observatory’s 8.4-meter primary/tertiary mirror is one step closer to revolutionizing the way astronomers capture and study the Universe. Both mirrors will soon be installed on the Simonyi Survey Telescope where they will collect the light of distant celestial objects and events during the 10-year Legacy Survey of Space and Time (LSST), beginning in 2025.

29 April 2024: Using the Gemini South telescope a team of astronomers have confirmed for the first time that differences in binary stars’ composition can originate from chemical variations in the cloud of stellar material from which they formed. The results help explain why stars born from the same molecular cloud can possess different chemical composition and host different planetary systems, as well as pose challenges to current stellar and planet formation models.

15 April 2024: Glittering threads of stars around the Milky Way may hold answers to one of our biggest questions about the Universe: what is dark matter? With images taken through six different color filters mounted to the largest camera ever built for astronomy and astrophysics, Vera C. Rubin Observatory’s upcoming Legacy Survey of Space and Time will reveal never-before-seen stellar streams around the Milky Way — and the telltale effects of their interactions with dark matter.
