A new study using data from NASA’s Lucy mission reveals that the asteroid Dinkinesh’s tiny moon “Selam” was built from multiple low-speed collisions between small moonlets, making it the first confirmed “contact binary” moon. Scientists now believe Selam formed not from two, but at least four separate bodies, offering fresh insight into how asteroid moons form and evolve.
A new Perspective published in Nature Astronomy provides the most comprehensive snapshot yet of the Universe’s first Billion years, as revealed by the James Webb Space Telescope (JWST). Drawn from the collective insights of an international assemblage of leading astronomers, the work charts a transformative moment in cosmic research—an era where science textbooks are being rewritten in real time.
A groundbreaking new study led by Marta Marcos, Discipline Scientist at the International Space Science Institute (ISSI), has revealed that the number of extreme marine heatwave days has nearly tripled since the 1940s—a dramatic shift driven largely by human-induced climate change.
Scientists supported by the International Space Science Institute (ISSI) in Bern have found that while Titan’s subsurface ocean could theoretically support microbial life through glycine fermentation, the availability and transport of organic material likely limit any potential biosphere to only a few kilograms of biomass.
An international team of astronomers has used the NASA/ESA/CSA James Webb Space Telescope to detect the first rich population of brown dwarf candidates outside the Milky Way in the star cluster NGC 602.
