Most alien-signal searches listen to a narrow part of the radio spectrum, but astronomers are now testing higher frequencies that have barely been explored. A first search using archived ALMA ...

Yet the key insight lies not in what was found, but in what the analysis revealed about the scale of previous searches.

K2-18b is one of the most promising worlds for the search for extraterrestrial life, so astronomers conducted an unusually powerful radio survey using both the VLA and MeerKAT telescopes. Advanced ...

A Ukrainian preprint reports more than 20 objects near the Moon, but missing distance data, independent confirmation and peer ...
