Serendipitous discovery of djerfisherite in Ryugu grain challenges current paradigm of the nature of primitive asteroids.

Astronomers have discovered a huge filament of hot gas bridging four galaxy clusters. At 10 times as massive as our galaxy, the thread could contain some of the universe’s ‘missing’ matter, addressing a decades-long mystery.

The SETI Institute and SpaceX have launched a groundbreaking collaboration to help protect sensitive radio astronomy observations at the Allen Telescope Array (ATA) from interference caused by satellite communications such as certain direct-to-cell signal transmissions from Starlink satellites. This effort represents a significant step forward in preserving the integrity of radio astronomy as satellite communications continue to expand global connectivity. SpaceX has previously reported on its collaboration with the National Radio Astronomy Observatory and the development of satellite boresight avoidance capabilities.

“The SETI Institute is at the forefront of developing solutions that allow for the continued exploration of the cosmos while accommodating the rapid evolution of satellite communications,” said Dr. David DeBoer, a researcher at the ATA. “Our collaboration with SpaceX is an important step in demonstrating that scientific discovery and technological progress can go hand in hand with the right coordination.”
