Turbulent plasma near distant stars could blur ultra-narrow signals before they leave their home star systems - making them ...

Comets are often treated as leftovers, but sometimes the leftovers become the primary focus. That is the case with 3I/ATLAS, only the third known interstellar object seen crossing the solar system, ...

A study by Johns Hopkins University has found that alien microbes could travel between planets on asteroids, meaning humans could be descended from Martians. Astrobiologists have long speculated that ...

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

SETI has spent decades listening for a sharp, well-defined radio signal that could indicate it was sent by distant intelligent life. Now researchers believe that space weather could distort and blur s ...

A new study has found that an asteroid NASA used for target practice a few years ago was nudged into a slightly different ...

Sci-fi masterpieces like Annihilation and Children of Men reward multiple rewatches, thanks to their complex narratives and ...

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

Crystal jellyfish have an eerie beauty: thanks to a natural protein, they emit a faint green glow. For decades, researchers ...

"If a signal gets broadened by its own star's environment, it can slip below our detection thresholds, even if it's there." ...

Asteroids with tiny moons may be quietly trading material across space. Images from NASA’s DART mission revealed faint ...

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