A group of Chinese scientists is diving deep into the cosmos in search of alien radio signals from the TRAPPIST-1 star system ...

Astronomers have detected alien signals - that is, signals from a foreign galaxy - being emitted in an unusually regular 16-day cycle. Fast radio bursts (FRBs) are not in and of themselves unusual - ...

A mysterious radio signal from our nearest stellar neighbour, Proxima Centauri, is being 'carefully investigated' by a team of alien-hunting astronomers. Researchers from the Breakthrough Listen ...

Scientists have sought out and detected radio emissions from from interstellar comet 3I/ATLAS, confirming what most ...

Scientists have captured mysterious radio signals traveling through space for more than a decade, baffled by what could be emitting such raging pulses. Some experts believe the fast radio bursts (FRBs ...

The bizarre signal, which was detected in late April 2019, sparked a great deal of enthusiasm among the scientific community last year. Picked up by the CSIRO radio telescope near Parkes in New South ...

Astronomers peering into the depths of space with a radio telescope array have traced the radio burst to the northern constellation Bootes. Preliminary data shows the signal originates from a lonely ...
