New SETI research suggests space weather like solar winds could be interfering with alien radio signals, making them harder ...

E.T. could be phoning home — but we’re not hearing the call. A new study published in The Astrophysical Journal argues that “space weather” could be distorting incoming transmissions from ...

The researchers who scan the skies for radio signals from extraterrestrials are now rethinking their approach.

Assuming intelligent aliens know how to harvest energy from stars, would humanity be able to spot these high-level structures?

We may be missing alien radio signals because they have become smeared beyond the narrowband detectors that SETI utilizes, a new study suggests.

Many people who don’t believe one conspiracy theory about that station—known as the High-frequency Active Auroral Research ...

Stellar plasma can smear alien radio signals before they escape their star system, making them harder for astronomers to detect.

Chalk up another victory for “Conan the Bacterium”—a rugged germ that fresh research suggests could conquer the solar system.

In Amiri’s calculations, Dyson spheres around white dwarfs tend to produce cooler, fainter thermal emission that peaks in the near- to mid-infrared, while M-dwarf cases can radiate more strongly but ...

Ever since physicist Freeman Dyson first proposed the concept in 1960, the "Dyson sphere" has been the holy grail of ...

What: SETI Institute Artists-in-Residence present Exoplanetary Poetry, an art-science collaboration that trains artificial intelligence on exoplanet atmospheric chemi ...
