Neutron stars thought to be silent actually emit faint radio signals. An unprecedented observation shows that these stars, ...

The “Wow!” signal is one of our best pieces of evidence for aliens, but researchers are building a compelling case for a more ...

There is a mysterious phenomenon in which strong radio signals arrive periodically from space, yet their source remains completely unknown. Known as “long-period radio transients" (LPTs), these ...

New research suggests that alien radio signals may be transformed by plasma from their home stars — and scientists on Earth could thus be overlooking prime evidence of alien intelligence.

The James Webb Space Telescope imaged galaxy NGC 4141, where astronomers traced the precise origin of a recent fast radio burst and its potential red giant companion, annotated in the inset as NIR-1.

For certain situations, older hardware is preferred or even needed to accomplish a task. This is common in industrial applications where old machinery might not be supported by modern hardware or ...

The search for extraterrestrial intelligence (SETI) has yet to detect alien technosignatures like radio waves, but the cosmos is vast, and there are plenty of places left to look. New research ...

When a radio signal is broadcast from a transmitter, some of it disappears upwards into space and is lost. However, during ...

Scientists have tracked an intense radio signal coming from deep in space to its origin – and been left shocked by what they found. For years, researchers have been looking to explain fast radio ...
