Press Releases

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.

4 April 2024: The Dark Energy Spectroscopic Instrument is conducting a five-year survey to create the largest 3D map of the Universe ever. Astronomers are now performing initial analysis of the survey’s first-year data. Using spectra of nearby galaxies and distant quasars, astronomers report that they have measured the expansion history of the Universe with the highest precision ever, providing an unprecedented look at the nature of dark energy and its effect on the Universe's large-scale structure.

3 April 2024: The world’s largest digital camera for astronomy is complete. Once in place on a telescope in Chile, the LSST Camera will gather an unprecedented amount of data about our Universe, yielding new insights into everything from dark energy to asteroids.

12 March 2024: With the powerful, 570-megapixel Department of Energy-fabricated Dark Energy Camera (DECam), astronomers have constructed a massive 1.3-gigapixel image showcasing the central part of the Vela Supernova Remnant, the cosmic corpse of a gigantic star that exploded as a supernova. DECam is one of the highest-performing wide-field imaging instruments in the world and is mounted on the US National Science Foundation's Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory, a Program of NSF NOIRLab.

29 February 2024: Using archival data from the Gemini North telescope, a team of astronomers have measured the heaviest pair of supermassive black holes ever found. The merging of two supermassive black holes is a phenomenon that has long been predicted, though never observed. This massive pair gives clues as to why such an event seems so unlikely in the Universe.

7 February 2024: Vera C. Rubin Observatory will help scientists identify intriguing targets to prioritize for future space missions by detecting millions of new Solar System objects, and by revealing — in more detail than we’ve ever seen — the broader context in which these objects exist. Additionally, Rubin may alert scientists to the existence of objects like asteroids, comets, or visiting interstellar objects in time to determine their trajectories and prepare space missions to study them.

29 January 2024: Journey Through the Universe — a partnership between the International Gemini Observatory, operated by NSF NOIRLab, and the Hawaiʻi Department of Education Hilo-Waiākea Complex Area — celebrates 20 years of cosmic exploration with Hawai‘i students and the community. This year’s exciting program includes classroom presentations, career panels, public events and more!

25 January 2024: The lenticular galaxy NGC 4753, captured by the Gemini South telescope, one half of the International Gemini Observatory operated by NSF NOIRLab, is a truly remarkable object. Its prominent and complex network of dust lanes that twist around its galactic nucleus define its ‘peculiar’ classification and are the likely result of a galactic merger with a nearby dwarf galaxy about 1.3 billion years ago.

8 January 2024: Using the DOE-fabricated Dark Energy Camera, mounted on the Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory, the Dark Energy Survey has obtained the largest supernova sample ever using a single telescope. By analyzing over 1500 distant supernovae, the DES collaboration has placed the strongest constraints on the expansion of the Universe ever obtained using supernovae and found hints that the Universe’s dark energy density may vary with time.

14 December 2023: Big Astronomy: People, Places, Discoveries is an award-winning bilingual planetarium show that takes viewers beyond the dome to behind the scenes of some of Chile’s world-class observatories. Meet the people who work with state-of-the-art telescopes in this feature film that is now free and available online for direct download.

4 December 2023: Intracluster light, the collective glow of innumerable stars stripped from their home galaxies and left to wander vast intergalactic space, is incredibly faint and difficult to detect. Vera C. Rubin Observatory’s upcoming Legacy Survey of Space and Time will be the first astronomical survey to provide scientists with the data they need to detect intracluster light in thousands of galaxy clusters, unlocking clues to the evolutionary history of the Universe on large scales.

27 November 2023: Through its Environmental Sustainability Program, NSF NOIRLab will reduce its entire annual carbon footprint by 50% by the end of 2027. This will be achieved through allocations of supplemental funding from the National Science Foundation towards installing solar panels and batteries at Gemini South and Vera C. Rubin Observatory in Chile as well as other upgrades at both NOIRLab’s Base and Summit facilities.

13 November 2023: Gemini North, one half of the International Gemini Observatory operated by NSF NOIRLab, is now peering deeper into the dusty dwellings of young stars with its new IGRINS-2 instrument. This next-generation spectrograph is an upgraded version of the high-demand visiting instrument IGRINS on Gemini South that will expand our understanding of cosmic objects shrouded by dust and gas.

8 November 2023: Astronomers using the Gemini North telescope, one half of the International Gemini Observatory operated by NSF NOIRLab, have captured the eroding remains of more than 100 dwarf galaxies as they transition into ultra-compact dwarf galaxies, objects with masses much greater than star clusters yet much smaller than dwarf galaxies. These findings confirm that many ultra-compact dwarf galaxies are likely the fossil remains of normal dwarf galaxies that have been stripped of their outer layers.

25 October 2023: Gemini South, one half of the International Gemini Observatory operated by NSF NOIRLab, captures the billion-year-old aftermath of a spiral galaxy collision. At the heart of this chaotic interaction, entwined and caught in the midst of the chaos, is a pair of supermassive black holes — the nearest pair to Earth ever recorded.

18 October 2023: Astronomers have created a detailed atlas of almost 400,000 galaxies in our cosmic neighborhood. The Siena Galaxy Atlas was compiled using data from NSF NOIRLab telescopes, and is designed to be the pre-eminent digital galaxy atlas for large galaxies. It’s a treasure trove of information for researchers investigating everything from galaxy formation and evolution to dark matter and gravitational waves. It’s also freely available online for the public to explore.

11 October 2023: Rubin Observatory’s Legacy Survey of Space and Time will help scientists map the large-scale structure of the Universe with finer precision than ever before. With Rubin’s wide field of view and high resolution, the subtle distortions of galaxy shapes caused by dark matter will be detectable, allowing scientists to map dark matter and explore its cosmic tug of war with dark energy.

5 October 2023: Using data from Gemini South and other observatories, astronomers have found a new Luminous Fast Blue Optical Transient (LFBOT), a powerful but poorly understood type of cosmic explosion. However, rather than being nestled in a star-forming galaxy like other LFBOTs discovered so far, the latest event, dubbed ‘the Finch’, occurred in the far outskirts of a galaxy. This observation calls into question leading ideas about the origins of these transient events.

28 September 2023: The symmetrical, onion-like layers of shell galaxy NGC 3923 are showcased in this galaxy-rich image taken by the US Department of Energy’s (DOE) Dark Energy Camera mounted on the National Science Foundation’s (NSF) Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory in Chile, a Program of NSF NOIRLab. A nearby, massive galaxy cluster is also captured exhibiting the phenomenon known as gravitational lensing.

21 September 2023: Kitt Peak National Observatory will begin a limited reopening program to welcome the public through its doors and domes starting Friday 22 September. Following a more than three-year closure as a result of the COVID-19 pandemic and the Contreras Fire, the historic KPNO will finally welcome visitors back to enjoy its guided daytime tours and nighttime observing programs.
