NASA's newly launched SPHEREx mission will use software developed at the Arizona Cosmology Lab to analyze data and help astronomers understand what happened in the first trillionth of a second after the Big Bang.

China has achieved a significant milestone in space science with the recent completion and national acceptance of the Chinese Meridian Project (CMP) Phase II on March 21. This project represents the world’s first comprehensive ground-based monitoring network spanning the entire Sun-Earth space environment, extending from the solar atmosphere to near-Earth space.

Two different teams of astronomers have detected oxygen in the most distant known galaxy, JADES-GS-z14-0. The discovery, reported in two separate studies, was made possible thanks to the Atacama Large Millimeter/submillimeter Array (ALMA), in which the European Southern Observatory (ESO) is a partner. This record-breaking detection is making astronomers rethink how quickly galaxies formed in the early Universe.

A newly published study in the Journal of Cosmology and Astroparticle Physics JCAP has not detected any signals attributable to quantum gravity effects in the neutrinos observed by the underwater detector KM3NeT/ORCA in the Mediterranean Sea. However, the result is significant because it establishes new experimental limits on quantum decoherence in neutrino oscillations—a phenomenon that, if detected, could indicate the existence of quantum gravity effects, a crucial piece in our understanding of the Universe and its fundamental laws. The identified limits further contribute to the ongoing effort to bridge quantum mechanics and general relativity.
