A first-of-its-kind study will scan 2,800 galaxies for extraterrestrial technology

The SETI Institute, the SETI Research Center in Berkeley, and the International Center for Radio Astronomy Research in Western Australia. The research is the first attempt to search for extraterrestrial technology in galaxies outside our galaxy, focusing on low frequencies
Clusters of satellites, such as the BlueWalker 3 prototype, are causing concern among astronomers due to possible interference with night sky observations and radio astronomy. Balancing the global needs for communication and maintaining astronomical research is critical. Credit: AST SpaceMobile

A prototype of a large low-orbit communications satellite is troubling astronomers

The BlueWalker 3 satellite whose antenna area is 64 square meters has become one of the brightest objects in the night sky, the fear is that when there are a hundred satellites in this constellation and hundreds in other constellations it will be impossible to watch the sky

SETI searches for technology signatures: The hunt for extraterrestrial signals at the heart of the Milky Way begins

Akshay Suresh, a graduate student at Cornell University, is leading an unusual scientific activity - a groundbreaking mission called BLIPSS to detect periodic signals emanating from the center of the Milky Way
