Looking for molecular evidence of life on other worlds is tricky, but a test based on the reactivity of carbon compounds ...

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.

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 ...

Invasive alien species don’t only drive out other native species, they also dramatically transform soils, water and ecosystems. A new assessment tool aims to pinpoint the negative environmental ...

Many of the most damaging invasions do not simply subtract species; they fundamentally remodel the environment, altering habitats, rewiring interactions, and shifting processes in ways that species ...

A new psychedelic retreat calling itself a “SETI for the mind” aims to establish two-way communication with the nonhuman entities people encounter while tripping on DMT.

For four decades, many SETI experiments have focused on finding sharp spikes in frequency but the new study says signals may not stay narrow as they travel away from their home system.

Beyond that, in the decades to come, we might be able to see the colours of an exoplanet’s surface, and determine if plant life might be present there. And then we can search for changes in a planet’s ...

The machines are built from autonomous modules that can be snapped together in a variety of forms ...

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

As a sci-fi series, Star Trek: Starfleet Academy has plenty of unrealistic aspects. But there's one that's so egregious, we ...
