Astronomers detect weird ‘heartbeat’ pulse of radio waves
There are all sorts of strange signals which we detect coming from space, and one set of signals which are particularly intriguing is called fast radio bursts. These incredibly bright pulses of radio energy are very brief, at just a few milliseconds in length, but they travel enormous distances between galaxies. Now, astronomers have discovered one such burst which not only has a surprisingly regular pattern but also lasts a much longer time....
