New SETI research suggests space weather like solar winds could be interfering with alien radio signals, making them harder to detect.
Radio silence has long puzzled those searching for extraterrestrial intelligence, but the answer might lie much closer to the source of potential signals than previously thought. Conditions around ...
We may be missing alien radio signals because they have become smeared beyond the narrowband detectors that SETI utilizes, a new study suggests.
The NASA/ESA Hubble Space Telescope reobserved interstellar comet 3I/ATLAS on 30 November with its Wide Field Camera 3 instrument. At the time, the comet was about 286 million kilometers from Earth.
For over six decades, the Search for Extraterrestrial Intelligence (SETI) has been tirelessly scanning the cosmos for signs of alien life. Despite its extensive efforts, the universe remains eerily ...
Harvard astrophysicist Avi Loeb says interstellar comet 3I/ATLAS likely comes from the Milky Way's disc, as astronomers ...
Scientists confirmed that the interstellar comet 3I/ATLAS, which passed closest to Earth in December 2025, showed no detectable technosignatures strong enough to suggest it is an alien spacecraft.
