Astronomers in Australia picked up a strange radio signal in June 2024 — one near our planet and so powerful that, for a ...

Satellites that retire are deorbited into a graveyard orbit within 25 years of their missions ending. This is the case with ...

A NASA satellite that had been inactive for almost sixty years surprised astronomers by sending a signal in June 2024.

Astronomers have finally deciphered the mystery of a peculiar bright burst in space, initially spotted using a large radio ...

A powerful and mysterious blast of radio waves that astronomers believed was a fast radio burst (FRB) from far beyond the ...

For a year, researchers tracked a brief but exceptionally powerful radio signal that came from space and outshone every other cosmic source in the sky.

As the satellite has been dead for nearly six decades, scientists believe that the signal must have come from an external factor, such as an electrostatic discharge or a micrometeorite.

As to why Relay-2 suddenly emitted this signal, that’s a mystery. The scientists behind the detection believe that the satellite may have built up electricity over the years and then suddenly ...

The Relay 2, a long-dead NASA satellite, had let out a powerful signal each time it passed over the astronomers' signal detection tools Credit: NASA. The fast radio burst (FRB), detected at the ...
