May's Blue Moon wows stargazers worldwide — see these stunning photos of the smallest full moon of 2026

• Astronomers may have decoded a mysterious signal consisting of powerful, regular bursts of energy originating from deep space. • Researchers are analyzing these periodic transmissions to determine the exact nature and source of the cosmic phenomenon.

• A new study suggests that current scientific methodologies for searching for extraterrestrial life may be overly cautious, potentially leading to "false negatives." • Researchers argue that strict criteria for what constitutes a biological signature could cause scientists to overlook genuine evidence of alien life.

• New research on mice suggests that a common anti-aging drug combination may cause brain damage, specifically severe myelin loss and symptoms similar to "chemo brain." • A review of 17 studies indicates that guava juice can significantly improve anemia in women and teenage girls by enhancing the body's iron absorption.

• The FAA issued an environmental assessment and a record of decision on May 15 approving test flights for SpaceX's "Starfall," an uncrewed reentry vehicle. • These vehicles are designed to support in-space manufacturing projects by safely returning materials from orbit to Earth.

• Scientists have developed a new solar desalination system that converts seawater into drinking water without producing toxic brine, a common byproduct of traditional methods. • The technology utilizes specialized laser-textured metal panels that harness sunlight to evaporate water and automatically remove salt deposits.

• The ISS National Lab hosted a dedicated track at the ASCEND 2026 conference to discuss the current state and future of research and development in low Earth orbit (LEO). • Former NASA official and current director of the Trivedi Institute for Space and Global Medicine, Rubins, highlighted the need to translate space-based discoveries into tangible benefits for human populations on Earth.

• Recent scientific research highlights how the decline of elephant populations is negatively impacting ecosystem stability and biodiversity. • A new innovation using rice paper has been developed to recycle gold from electronic waste, offering a more sustainable method of mineral recovery.

• Engineers at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, have completed the final inspection of the primary mirror for the Nancy Grace Roman Space Telescope. • This critical phase ensures the telescope's optical components are precise and ready for deployment after the sunshade was successfully tested.

• NASA Science is hosting a PhysPAG Community Webinar on June 2, 2026, from 2:00 PM to 3:00 PM Eastern Time to discuss the ASTRA Initiative. • The initiative focuses on driving science questions and exploring the trade space for various implementation options for new mission concepts.

• A rare Blue Moon will occur on May 30, 2026, marking the second full moon to appear within a single calendar month. • This celestial event provides a unique viewing opportunity for stargazers to witness the moon at its peak illumination.

• China has launched "human artificial embryos," created from living stem cells, to the Tiangong space station via the Tianzhou-10 mission. • These embryo-like structures will be used in experiments to study the specific effects of microgravity and cosmic radiation on human reproduction.
