13 Enero 2021: Scientists and science communication professionals from a collection of institutes, including the National Science Foundation (NSF), NSF’s NOIRLab, NASA, AURA, and various European observatories, have published a white paper detailing best practices for science communication on behalf of large, multi-institutional collaborations. The biggest breakthroughs in science have always relied on collaboration, and the scale and complexity of astronomical collaborations have increased as astronomers set more and more complex goals. From the Event Horizon Telescopes’s worldwide network of 13 telescopes to the LIGO Scientific Collaboration, big science is increasingly done by large, international, multi-institutional collaborations. This plurality of scientists, instruments, and collaborations enables unprecedented scientific discoveries but also makes communicating results difficult. Communicating breakthroughs from collaborators scattered across the globe poses a formidable challenge in timing, cooperation, and coordination. Scientists and astronomy communication professionals from around the world gathered to address these challenges at a summit in November 2019. Drawing on …

12 Enero 2021: From 5 to 9 October 2020, more than 950 people took part in an online Workshop on Dark and Quiet Skies for Science and Society.

The variety of celestial objects, each one a unique shape or size, symbolizes Rubin Observatory’s commitment to diversity. The curved lines invoke …

22 Noviembre 2020: An international team of astronomers has identified the nature of Earth’s second known minimoon, 2020 CD3, following its discovery by the Catalina Sky Survey and follow-up imaging with the international Gemini Observatory, a Program of NSF’s NOIRLab, earlier this year. Upon its discovery the object was compelling but mysterious, with astronomers unsure if it was a rare natural rocky object or a lost piece of space junk. Now, observations from a collection of telescopes including Gemini North on Hawai‘i’s Maunakea have shown 2020 CD3 to be natural in origin. The minimoon is a rocky remnant of a larger body and measures about 1–1.5 metres (3–5 feet) across — roughly the size of a large desk. The team also found that 2020 CD3 was only a temporary visitor to Earth — after spending 2.7 years in orbit it was ejected to roam the Solar System in April this year. As well …

17 Noviembre 2020: Project & Science News Construction activity on Cerro Pachón continues to expand, with approximately 40 people working on the summit each day last week.

21 Octubre 2020: Project & Science News Last week, at SLAC National Accelerator Laboratory, the LSST Camera team conducted a successful test verifying the clearance between the filters and the shutter as the filter moves from its storage position to its online position. The level of clearance is extremely small to meet the optical design distance between the filter and the L3 lens. The completion of this test is significant for the Rubin Project because it retires some key interface risks for the Camera. Additional tests that will further verify the interoperability of the various Camera components are ongoing. Photos and video of the tests are available in the Gallery. An informative article on how Rubin Observatory and the LSST Camera will advance the study of dark matter, titled “A Powerful New Tool to Study the Cosmos,” was published in Symmetry Magazine on October 13th.
