Astrophysicists caught a cryptic signal from space

A 2-millisecond radio burst was recorded by the Canadian CHIME telescope.

The frequency was unusually low for signals of this kind – only 580 megahertz. Usually such radio bursts have a frequency of at least 700 MHz. It was the telescope CHIME, located in Canada, which registered it.

Such a radio burst was first recorded in 2007. Over the next 10 years, astrophysicists recorded several more such signals, but in no case they were able to determine exactly where the impulses came from. Fast radio bursts are always very powerful – the energy of one such signal is equal to the one that Sun generates over tens of thousands of years.

There are many versions of the origin of rapid radio bursts. The most common – such signals occur when two neutron stars merge. Some scientists believe that such powerful radio pulses can generate stars of the Milky Way. However, the extraordinary power and the absence of a single reliable theory makes many scientists attribute fast radio bursts to the activities of extraterrestrial civilizations. Who knows – maybe CHIME intercepted a piece of dialogue of aliens?
