elevation, and strict light pollution controls. This breathtaking shot shows the Milky Way above U.S. National Science Foundation Kitt Peak National Observatory (KPNO), a Program of NSF NOIRLab. KPNO is the largest assembly of optical instruments in the northern hemisphere and is a leading site for astronomical research. The Burrell Schmidt telescope on the left was relocated to KPNO from Case Western Reserve University to escape the increasing light pollution in Cleveland, Ohio. In the middle is the 0.9-meter SARA Kitt Peak Telescope. It was originally known as the No. 1 36-inch telescope of the predecessor of NOIRLab, National Optical Astronomy Observatories (NOAO), but today the telescope is operated by the Southeastern Association for Research in Astronomy, a consortium of universities throughout the southeast United States.

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. Airglow is primarily caused by sunlight interacting with atoms and molecules in Earth’s upper atmosphere, which allows them to gain excess energy. This excess energy is then released as a particle of light called a photon.

Located around four million light-years from Earth in the constellation Hydra, it’s about 40,000 light-years across. Despite its beautiful blue hues, this irregular dwarf galaxy appears featureless with no central bulge or picturesque arms. However, spectroscopic analysis has shown that NGC 3109 is one of the most metal-poor galaxies in the Local Group. For most of us, metals are conductive, malleable elements like aluminum or copper, but to astronomers metals are all elements other than hydrogen and helium — such as carbon, nitrogen and oxygen. Stars consume hydrogen and helium to produce heavier elements. These metals are released into the interstellar medium when a star dies and are found in successive generations of stars. Metal-poor galaxies like NGC 3109 have a similar composition to the stars — and therefore the galaxies …</div> </div> <div class="news-readmore">Read more</div> </div>  </a> </div> <div class="col-md-3 col-sm-6 col-xs-12"> <a href="/public/images/iotw2507a/" aria-label="iotw2507 — Image of the Week"> <div class="news-wrapper"> <div class="news-image"> <img class="img-responsive" src="/public/media/archives/images/thumb350x/iotw2507a.jpg" alt="Comet C/2024 G3 (ATLAS) in the Chilean Skies"> </div> <div class="news-description"> <div class="news-id">iotw2507 — Image of the Week</div> <div class="news-title">Comet C/2024 G3 (ATLAS) in the Chilean Skies</div> <div class="news-teaser"><strong>12 February 2025</strong>: Comet C/2024 G3 (ATLAS) is captured here in all its beauty by Cesar Briceño, Director of 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. Comets form from a nucleus of dust, water, and gas in the farthest-known regions of our Solar System. This close-up of the Comet C/2024 G3 (ATLAS) cleanly shows the vaporized material of the nucleus creating the iconic cometary shape. In the lower left corner, the diffuse coma shines bright white as it obscures the nucleus. Emanating from the nucleus are the twin tails. The upper stream is the dust tail made of the heavier dust particles, illuminated by reflected sunlight. The lower stream is composed of gases, glowing as a result of ionization of the gas atoms.

Stars appear to move across the sky during the night as a result of Earth’s rotation. This effect is captured beautifully here using long-exposure photography, a photographic technique where stationary objects appear defined while moving objects appear blurred. In this image, these dizzying arcs of light trace the apparent motion of stars in the sky. Stars that are far away from the celestial poles appear to move more over time and thus display longer star trails compared to stars near the celestial poles.

CTIO is located at an altitude of 2200 meters (7200 feet) in the remote mountains of Chile. This location, high in the sky and far from city light pollution, allows telescopes like the Blanco Telescope to study the sky in breathtaking clarity. This image encapsulates the beauty of the cosmos and the sophisticated efforts undertaken by astronomers to unravel its mysteries. One such effort in which this telescope has played a major role is the Dark Energy Survey (DES).

Southwest of Tucson, the Quinlan Mountains majestically rise to an altitude of 2100 meters (7000 feet) in the Schuk Toak District of the Tohono O’odham Nation. Atop the central peak in this image sits the U.S. National Science Foundation Kitt Peak National Observatory (KPNO), a Program of NSF NOIRLab and the largest collection of optical and radio telescopes in the northern hemisphere. Kitt Peak’s ideal vantage point, combined with the dark, dry environment of the desert, allows astronomers to make discoveries in many areas of astronomy including exoplanets, galaxies, and dark energy.

Every so often, though, Gemini North is the site of something special. Upon closer inspection, a stream of shadow can be seen streaking across the right side of the image, outlined by parallel beams of light known as anticrepuscular rays. These rays are caused by clouds obscuring the dim, backscattered sunlight and appear to converge on a point directly opposite the Sun, known as the antisolar point. If these rays originated directly from the Sun, they would be called crepuscular rays. Anticrepuscular rays require the right environment to be created so they are difficult to glimpse.</div> </div> <div class="news-readmore">Read more</div> </div>  </a> </div> <div class="col-md-3 col-sm-6 col-xs-12"> <a href="/public/images/iotw2452a/" aria-label="iotw2452 — Image of the Week"> <div class="news-wrapper"> <div class="news-image"> <img class="img-responsive" src="/public/media/archives/images/thumb350x/iotw2452a.jpg" alt="Navigating the Milky Way"> </div> <div class="news-description"> <div class="news-id">iotw2452 — Image of the Week</div> <div class="news-title">Navigating the Milky Way</div> <div class="news-teaser"><strong>25 December 2024</strong>: The Milky Way, looking like a river of stars and dust, stretches between the Víctor M.

Also known as Caldwell 30, this galaxy is often thought of as a twin to the Milky Way owing to its similar size and spiral structure. However, there are a couple of features of its core that set it apart from our home galaxy. For instance, astronomers have found evidence that the Milky Way has a central bar of stars and dust cutting through its center, a feature common to many spiral galaxies. But NGC 7331 lacks this feature. Additionally, NGC 7331’s central bulge rotates in the opposite direction to its galactic disk — …</div> </div> <div class="news-readmore">Read more</div> </div>  </a> </div> </div> <div class="row news-list news-list-overflow"> <div class="col-md-3 col-sm-6 col-xs-12"> <a href="/public/images/iotw2450a/" aria-label="iotw2450 — Image of the Week"> <div class="news-wrapper"> <div class="news-image"> <img class="img-responsive" src="/public/media/archives/images/thumb350x/iotw2450a.jpg" alt="Happy Holidays 2024"> </div> <div class="news-description"> <div class="news-id">iotw2450 — Image of the Week</div> <div class="news-title">Happy Holidays 2024</div> <div class="news-teaser"><strong>11 December 2024</strong>: We at NOIRLab, funded by the U.S. National Science Foundation (NSF), would like to wish you the best this holiday season, and a successful and prosperous 2025!

Rubin Observatory is located on Cerro Pachón at an altitude of 2600 meters (8600 feet). In the distance to the right of Rubin Observatory is the mountaintop Cerro Tololo, home to the NSF Cerro Tololo Inter-American Observatory (CTIO), a Program of NSF NOIRLab. The structure at the top of Cerro Tololo is the Víctor M. Blanco 4-meter Telescope, located at an altitude of approximately 2200 meters (7200 feet). Together Cerro Pachón and Cerro Tololo form a major astronomical observation hub.

The long exposure time of this photograph, coupled with the rotation of Earth, has caused the stars to streak into a multitude of graceful arcs. To the right of the image a much more earthly trail is visible; hikers with head torches have illuminated the final stretch of the Humuʻula Trail which winds up to the summit of Maunakea.

CTIO is a complex of astronomical telescopes and instruments that has long served as the principal platform for American astronomical investigation of the southern skies. In addition to the many telescopes it operates, CTIO provides space for others to access the southern sky — almost a dozen tenant observatories are hosted at the site. Pictured here are telescopes operated by Las Cumbres Observatory (LCO). LCO operates a network of telescopes spread out longitudinally across the northern and southern hemispheres. The strategic positioning of its telescopes means that LCO always has a telescope in darkness and it can coordinate its telescopes to quickly collect data that would be missed by …</div> </div> <div class="news-readmore">Read more</div> </div>  </a> </div> </div> <div class="row news-list news-list-overflow"> <div class="col-md-3 col-sm-6 col-xs-12"> <a href="/public/images/iotw2446a/" aria-label="iotw2446 — Image of the Week"> <div class="news-wrapper"> <div class="news-image"> <img class="img-responsive" src="/public/media/archives/images/thumb350x/iotw2446a.jpg" alt="Grandeur Around Gemini South"> </div> <div class="news-description"> <div class="news-id">iotw2446 — Image of the Week</div> <div class="news-title">Grandeur Around Gemini South</div> <div class="news-teaser"><strong>13 November 2024</strong>: Gemini South, one half of the International Gemini Observatory which is supported in part by the U.S. National Science Foundation and operated by NSF NOIRLab, sits high atop Cerro Pachón in Chile, surrounded by gems of the southern night sky. One of these gems, the center of our Milky Way, is also the center of this image. The heart of our galaxy, densely packed with stars, is home to a supermassive black hole, known as Sagittarius A*, surrounded by the colossal clouds of cosmic dust of the Great Rift. While difficult to see in this image, these dark clouds house many interesting and beautiful deep-sky objects, like Ptolemy’s Cluster (Messier 7) and the Cat’s Paw Nebula (NGC 6334).

Down on the mountain at the center of the image, a snaking band of light marks the location of an access road. In the distance, the large cities on the Island of Hawai‘i light up spots under the clouds while the active volcano Mauna Loa rises above them. Just like Mauna Loa, Maunakea is a shield volcano — though thankfully a dormant one. However, the volcanic past of Maunakea continues to be an asset to astronomers. The mountain’s smoothly sloping sides and high elevation are two of the factors that contribute to the exceptional observing conditions at the summit.</div> </div> <div class="news-readmore">Read more</div> </div>  </a> </div> <div class="col-md-3 col-sm-6 col-xs-12"> <a href="/public/images/iotw2444a/" aria-label="iotw2444 — Image of the Week"> <div class="news-wrapper"> <div class="news-image"> <img class="img-responsive" src="/public/media/archives/images/thumb350x/iotw2444a.jpg" alt="A Stargazer’s View from Kitt Peak"> </div> <div class="news-description"> <div class="news-id">iotw2444 — Image of the Week</div> <div class="news-title">A Stargazer’s View from Kitt Peak</div> <div class="news-teaser"><strong>30 October 2024</strong>: The Milky Way is a disk-shaped spiral galaxy with many arms, each holding countless stars and celestial objects.

This photographer instead looked toward Orion — identifiable by the distinct three-star ‘belt’ — for this Image of the Week to capture the Orion-Cygnus Arm. The bright stars, clusters, and nebulae, such as the red giant Aldebaran (center) and the Orion Nebula (center right), that lie within the arm hold significance for cultures across the globe and are areas ripe for exploring many astrophysical processes.

One such example is the lunar eclipse taking place in the distance on the right side of this image, captured in 2019. It is seemingly encased in the dark blue band above the horizon. Lunar eclipses occur when Earth moves between the Sun and the Moon. The Moon, which is only visible by the sunlight reflected off it, is darkened by the Earth’s shadow. An eclipse like this one can be viewed from anywhere on Earth where the Moon is visible, though the extent of the eclipse depends on how aligned the Moon is to Earth’s shadow and one’s viewing location.
