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, ...

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

The reason we haven’t heard from aliens could be remarkably simple: interstellar communication is hard, and turbulent plasma ...

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 shows that stars with low magnetic activity are likely to support exoplanetary systems, making the hunt for these ...

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

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

We might have missed signals from aliens because they are being disrupted by the conditions of space, scientists have warned.

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 ...

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 ...

Scientists identify exoplanet candidate HD 137010 b, a possible Earth-size world orbiting a Sun-like star 146 light-years away ...

The first bubble of hot gas seen around another star has been spotted around the "Moth," just 117 light-years away.
