2 April 2025: In an alignment of celestial bodies, Mars was captured here rising out of a lunar occultation on 13 January 2025 using the new Visitor Center 0.6-meter Shreve Telescope at the U.S. National Science Foundation Kitt Peak National Observatory (KPNO), a Program of NSF NOIRLab, near Tucson, Arizona. An occultation is when an object becomes hidden from an observer’s view by another object passing between them. The passing object must be larger than the hidden object. Otherwise the event is a transit, such as the transit of Mercury in front of the Sun in 2019, as photographed from NSF Cerro Tololo International Observatory (CTIO), another Program of NSF NOIRLab.

3 March 2025: The Milky Way shares the stage with a luminous bubble of green and orange airglow in this panoramic image of Gemini North, one half of the International Gemini Observatory, supported in part by the U.S. National Science Foundation (NSF) and operated by NSF NOIRLab. Gemini North (right) is accompanied here by the Canada-France-Hawai‘i Telescope (CFHT) (left). In this image, you could remove all of the stars, the brilliant stripe of the Milky Way, and the nearby city lights of Hilo, Hawai‘i (far left), and you would still be left with a picture that isn’t completely dark. This is thanks to the persistent light of airglow. Read More

3 March 2025: While NOIRLab works to unravel the secrets of the Universe, you can start your own journey to explore the night sky right from your backyard. There are plenty of celestial events for skywatchers to observe every month. Below are some highlights. If you’d like to explore more on your own, we recommend Stellarium, which has a web interface and app. 1 March: Three planets hang out with the Moon After sunset, look for Venus and Mercury near the sliver of a crescent Moon. Venus will be the brighter planet. Saturn will also be hanging out low on the horizon, but it may get lost in the Sun’s glare. Jupiter and Mars will also be visible. 5 March: Pointing the way to the Seven Sisters After sunset, look for Mars, Jupiter, and the Moon roughly lined up with the star cluster M45, also known as the Pleiades or Seven Sisters. Venus …

3 March 2025: Visits by students, teachers, and the general public are a relevant part of the outreach, engagement, and education work carried out by scientific observatories in their approach to sustainable relationships with local host communities. To that end, most of these facilities were conceived from the outset with spaces to receive visitors. Their purpose is to make the scientific work they perform, and the benefit it provides to technological development and the creation of knowledge, known to the public. This is why all NSF NOIRLab facilities at our summits and bases offer public visits at some point during the week and/or month, throughout the calendar year. The NOIRLab Communications, Education and Engagement team that developed the procedure, logistics, and content of public visits to make sure that significant and understandable content is delivered, and that school-related physics topics are covered, such as gravity, the decomposition of light, the expansion of the …

3 March 2025: NSF NOIRLab joined the 86th Annual Tohono O’odham Nation Rodeo & Fair in Sells, Arizona on 1 February 2025. The annual rodeo was free this year and brought together O’odham tribal members and guests to celebrate the Nation’s culture and history. NOIRLab participated in the Rodeo Parade on Saturday morning along Main Street with the theme of superheroes. NOIRLab’s float celebrated past and present O’odham NOIRLab employees as well as those who have supported the observatory for over 60 years. NOIRLab acknowledged current staff members from the Tohono O’odham Nation including Zade Arnold, Keith Blaine, Sadie Carmen, Leander Garcia, Wynona Juan, Reynese Maldonado, Jacelle Ramon-Sauberan and Vivian Segundo.

31 January 2025: Comet C/2024 G3 (ATLAS) gleams against the January sky above three NOIRLab-supported telescopes in this Image of the Week. This is the first time that humans have observed this comet, which was last visible from Earth about 600,000 years ago. At perihelion, this comet reached an apparent magnitude of -3.8. This is about the same brightness as Venus, on the right side of the image, and potentially makes it the brightest comet of 2025. The straight lines across the sky are satellites, more prominently visible in this close-up. This image was taken atop Cerro Pachón, in the foothills of the Chilean Andes, next to the Southern Astrophysical Research Telescope (SOAR), a part of the U.S. National Science Foundation (NSF) Cerro Tololo Inter-American Observatory (CTIO), a Program of NSF NOIRLab. In the distance are two other observatories supported by NSF NOIRLab (left to right): Gemini South, one half of the International …

31 January 2025: Supernovae are grand cosmic explosions that mark the endpoint of some stars. Their brief but brilliant appearances can outshine the light of an entire galaxy! Before the year 2000, only 300 supernovae had ever been detected, but in the last few decades machine learning and sky surveys have increased the total number of supernova detections to more than 50,000. Impressive, right? And later this year, when NSF–DOE Vera C. Rubin Observatory begins the Legacy Survey of Space and Time, the number of supernova detections will surpass the entire historical tally in just a few months! This is due to Rubin Observatory’s ability to repeatedly take very large and detailed images on short time scales. For any supernova captured in these images, scientists can construct a light curve, which shows how the supernova’s light changes over time. Scientists use light curves to classify the type of supernova. Type Ia supernovae are …

2 January 2025: While NOIRLab works to unravel the secrets of the Universe, you can start your own journey to explore the night sky right from your backyard. There are plenty of celestial events for skywatchers to observe every month. Below are some highlights. If you’d like to explore more on your own, we recommend Stellarium, which has a web interface and app. 3–4 January: Venus, the Moon, and Saturn Line Up On 3 January, Venus, a crescent Moon, and Saturn will line up neatly in the evening sky. Jupiter will also be visible in the east. The lineup will change on 4 January, when Saturn will be between the Moon and Venus. 9 January: The Moon and the Seven Sisters On 9 January, the Moon will be right next to the Pleiades, also known as M45 or the Seven Sisters. Unfortunately the Moon will be 83% full, which will make it difficult …

Consider learning more about astronomy on Maunakea and the night sky from …

2 January 2025: The Dark Energy Spectroscopic Instrument (DESI) is an advanced spectrograph capable of measuring the redshifts of 5000 galaxies simultaneously. DESI is probing dark energy — the mysterious force that is causing the expansion of the Universe to accelerate. With such a vast amount of data, other types of analysis can be done as well. Using the first year of DESI data (containing nearly six million galaxies spanning over 11 billion years of the history of the Universe), researchers created the largest 3D map of the Universe ever. Analyzing this map allowed researchers to test Einstein’s general theory of relativity over vast cosmic distances more precisely than has ever been possible. They found that the observed structure of the Universe matches very well with Einstein’s predictions of how gravity behaves at large scales, and their results place limits on other theories of gravity that have been proposed to explain dark energy. …

2 January 2025: The International Astronomical Union (IAU) divides the sky into 88 official constellations. The newly launched 88 Constellations project from NSF NOIRLab brings together high-resolution images and educational resources to help bring the 88 constellations into your classroom. German astrophotographer Eckhard Slawik meticulously photographed the 88 constellations on film. The final images are each composed of two separate exposures — one with a diffuser and one without to bring out the natural colors of the stars. NOIRLab staff added information on the constellations, their history, and interesting objects visible in each constellation. This resource would complement classroom instruction relating to observing motions and patterns of the night sky, designing solutions for light pollution, and preserving the dark sky. Classroom activities can also be found at globeatnight.org. For more information, read the full announcement here.
