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

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 ...

A new study by researchers at the SETI Institute suggests stellar “space weather” could make radio signals from extraterrestrial intelligence harder to detect. Stellar activity and plasma ...

The Fermi Paradox asks a simple but unsettling question: if the universe is so vast, why haven’t we found evidence of alien civilizations? Scientists have proposed many explanations, but some of the ...

Solar storms around distant stars may be erasing alien radio signals before we ever hear them In A Nutshell Stellar winds and ...

We might have missed signals from aliens because they are being disrupted by the conditions of space, scientists have warned. Messages being sent from distant planets could be disrupted by activity ...

A new study by researchers at the SETI Institute suggests stellar "space weather" could make radio signals from ...

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 ...

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

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

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 ...

Our search for extraterrestrial life has turned up empty, perhaps because technologically advanced civilizations are doomed ...
