Astronomer have received five mysterious signals coming from outside the Milky Way. One of the theory explaining these mysterious signals by astronomers is that they may have been sent by an alien civilization. Up to now, only 11 of these bizarre radio signals have been documented before around the world. The newest signal, which was picked up by the Parkes radio telescope located in Australia, comprised a new double blast along with four 'single' bursts. Emily Petroff of Swinburne University, who assisted in discovering the pulses, has proposed this pattern may lead to a significant discovery. She said in tweet, “We have no idea what's going on, but we know it's definitely something cool.”
They say each burst was parted by almost 2.4 milliseconds.
The team said: “Many of the proposed models to explain FRBs use a single high energy event involving compact objects (such as neutron star mergers) and therefore cannot easily explain a two-component FRB.”
The first FRB was discovered, or rather 'heard' by radio telescopes, back in 2007. But it was so brief and apparently random that it took years for astronomers to decide it wasn't a malfunction in one of the telescope's instruments.
The signal, which persisted only five milliseconds, is proposed to have come from a great distance away, perhaps billions of light-years.
