DECam’s Deep View of Abell 3667 Illuminates the Past of a Galaxy Cluster and the Future of Astronomical Imaging

An actively merging galaxy cluster is featured in this image assembled from a total of 28 hours of observations with the 570-megapixel 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. The image gives a tantalizing hint of how intracluster light will be revealed by NSF–DOE Vera C. Rubin Observatory’s Legacy Survey of Space and Time.

Gemini North Discovers Long-Predicted Stellar Companion of Betelgeuse

Astronomers have discovered a companion star in an incredibly tight orbit around Betelgeuse using the NASA and U.S. National Science Foundation-funded ‘Alopeke instrument on Gemini North, one half of the International Gemini Observatory, partly funded by the NSF and operated by NSF NOIRLab. This discovery answers the longstanding mystery of the star’s varying brightness and provides insight into the physical mechanisms behind other variable red supergiants.

Gemini North Observes Comet 3I/ATLAS

Interstellar objects are visitors from solar systems beyond our own, and the third ever such object, known as 3I/ATLAS, has just been discovered. Using the Gemini North telescope, astronomers have captured 3I/ATLAS as it makes its temporary passage through our cosmic neighborhood. These observations will help scientists study the characteristics of this rare object’s origin, orbit, and composition.

NASA’s Webb Scratches Beyond Surface of Cat’s Paw for 3rd Anniversary

It’s the cat’s meow! To celebrate its third year of revealing stunning scenes of the cosmos in infrared light, NASA’s James Webb Space Telescope has “clawed” back the thick, dusty layers of a section within the Cat’s Paw Nebula (NGC 6334). Focusing Webb’s NIRCam (Near-Infrared Camera) on a single “toe bean” within this active star-forming region revealed a subset of mini toe beans, which appear to contain young stars shaping the surrounding gas and dust.

International Gemini Observatory and SOAR Discover Surprising Link Between Fast X-ray Transients and the Explosive Death of Massive Stars

Using a combination of telescopes, including the International Gemini Observatory, funded in part by the U.S. National Science Foundation and operated by NSF NOIRLab, and the SOAR telescope at Cerro Tololo Inter-American Observatory in Chile, a Program of NSF NOIRLab, astronomers have characterized the closest supernova linked to a fast X-ray transient. The observations reveal that these bright blasts of X-rays may be the result of a ‘failed’ explosive death of a massive star.

Likely Saturn-Mass Planet Imaged by NASA Webb Is Lightest Ever Seen

Astronomers using NASA’s James Webb Space Telescope have captured compelling evidence of a planet with a mass similar to Saturn orbiting the young nearby star TWA 7. If confirmed, this would represent Webb’s first direct image discovery of a planet, and the lightest planet ever seen with this technique outside the solar system.

Ever-changing Universe Revealed in First Imagery From NSF–DOE Vera C. Rubin Observatory

The NSF-DOE Vera C. Rubin Observatory, a major new scientific facility jointly funded by the U.S. National Science Foundation and the U.S. Department of Energy’s Office of Science, released its first imagery today at an event in Washington, D.C. The imagery shows cosmic phenomena captured at an unprecedented scale. In just over 10 hours of test observations, NSF-DOE Rubin Observatory has already captured millions of galaxies and Milky Way stars and thousands of asteroids. The imagery is a small preview of Rubin Observatory’s upcoming 10-year scientific mission to explore and understand some of the universe’s biggest mysteries.
