Scientists at the world-famous 'Dish' were shocked to find the unusual signals they were picking up actual came from the kitchen microwave.
The telescope facility, CSIRO Parkes Observatory, detected 'fast radio bursts' signals originally thought to be intergalactic.
"We were getting some strange signals that appeared to be coming from very nearby," PhD student Emily Petroff told the ABC.
"It turns out that you can generate these particular local signals by opening the door of the microwave to stop the microwave, and that produces these weird bursts that we're seeing at Parkes."
Ms Petroff is part of the team from Swinburne University who have already achieved a world first by capturing alien radio signals soaring through space.
