An international collaboration of astronomers has produced one of the most precise measurements yet of how fast the local Universe is expanding. The result deepens one of the most significant challenges in modern cosmology. John Blakeslee, astronomer at NSF NOIRLab, funded by the U.S. National Science Foundation, is a member of the collaboration, and telescopes across two NSF NOIRLab Programs contributed data.

Aaron Rosengren, space systems faculty member, Department of Mechanical and Aerospace Engineering, University of California San Diego, comments on why Artemis II will be splashing down off San Diego. 

The Center for Myokine Convergence Research at Korea University College of Medicine (Director: Professor Hyeon Soo Kim, Department of Anatomy, Korea University College of Medicine) has signed a memorandum of understanding (MOU) with MFC to jointly develop therapeutics for muscle loss in astronauts.

In 1972, a series of solar proton events occurred between the Apollo 16 and 17 missions. Had they coincided, astronauts would have been exposed to deadly particle radiation with very little warning and no shielding. As we return to the Moon, understanding these volatile events is increasingly urgent. 

Guided by a medieval Japanese poet and tree-ring analysis of buried cypress trees, researchers have achieved world-leading precision in carbon-14 measurements, finding evidence supporting the occurrence of a solar proton event dated to winter 1200 CE–spring 1201 CE. This research helps fill gaps in our knowledge of extreme space weather and its relation to solar cycles. 

Deep underground in a Canadian mine, scientists have cooled a massive refrigerator to nearly 1,000 times colder than outer space, a key milestone in the search for dark matter. The achievement enables Texas A&M-designed detectors at the core of the Super Cryogenic Dark Matter Search (SuperCDMS) experiment at SNOLAB in Ontario to reach the extreme sensitivity needed to spot interactions from elusive “light dark matter."
