28 October 2024: NSF–DOE Vera C. Rubin Observatory passed its first end-to-end engineering test using a low-resolution testing camera known as the Commissioning Camera. The Commissioning Camera will later be replaced with the much higher resolution LSST Camera, the largest digital camera ever built, which Rubin Observatory will use to conduct the most comprehensive data-gathering mission in the history of astronomy — the 10-year Legacy Survey of Space and Time. Rubin is funded by the U.S. National Science Foundation and U.S. Department of Energy's Office of Science. The mood in the observatory control room was electric as Rubin’s first on-sky data were captured by the test camera and transferred successfully from the observatory in Chile to the U.S. Data Facility at SLAC National Accelerator Laboratory in California. This moment was the culmination of decades of hard work by the Rubin team. Those present in Chile gathered at the base of the Simonyi Telescope …

17 October 2024: Between 30 September and 3 October NSF NOIRLab hosted the First Gigayear(s) Conference at the Hilo Hawaiian Hotel.

3 October 2024: Have you ever wondered what might happen to our Solar System in a few billion years? The Sun will eventually turn into a white dwarf — a dead remnant of its current self — consuming the inner planets along the way. Some white dwarfs are surrounded by dusty disks containing asteroids, comets, and other remnants of their planetary systems. These disks are excellent laboratories for studying the end stage of planetary systems, providing unique information about the formation and death of planets. To help search for examples of asteroids orbiting white dwarfs in the Milky Way, NSF NOIRLab has launched the Exoasteroids citizen science project. With the help of volunteers, this project is aimed at identifying white dwarfs that have changed in brightness over the past decade. Such fluctuations may indicate that a white dwarf is the remnant of a planetary system still actively destroying its lingering exoasteroids, leading to …

2 October 2024: Multi-messenger astronomy is a powerful new tool for exploring the cosmos that combines the information from multiple types of signals to understand a single astronomical source or event. The four messengers that astronomers study are light, cosmic rays, neutrinos and gravitational waves. Because a source can change rapidly, it’s critical that observations of these messengers occur simultaneously or within a short time span so that astronomers capture their properties before the source changes. However, it’s quite the challenge to coordinate follow-up from multiple optical observatories across the globe — each with its own instruments — while minimizing duplication and maximizing the value of the combined dataset. That’s why the U.S. National Science Foundation has awarded $2 million in funding to the National Center for Supercomputing Applications (NCSA) and the Center for AstroPhysical Surveys (CAPS), in collaboration with NSF NOIRLab and Las Cumbres Observatory, to build a service that allows researchers …

28 August 2024: Just how dark is deep space? In 2021 a team of astronomers, including Tod Lauer of the U.S. National Science Foundation-funded NSF NOIRLab, attempted to answer this long standing question by tapping into the capabilities and distant position of NASA’s New Horizons spacecraft [1], which allowed them to make the most precise, direct measurements ever of the total amount of light the Universe generates. The results surprisingly showed that the Universe was brighter than expected, and the origin of the mysterious ‘extra light’ became the question. Now, thanks to new and improved data from New Horizons, the team [2] has determined that this extra light was actually a consequence of contaminating foreground light. More than 18 years after launch and nine years after its historic exploration of Pluto, New Horizons is more than 7.3 billion kilometers (5.4 billion miles) from Earth, in a region of the Solar System far enough …
