In a first, scientists detect ‘fast radio bursts’ from beyond the Milky Way galaxy

LA Times  

Sifting through the heavens like prospectors panning silt for a glint of gold, astronomers say they have finally pinpointed the source of so-called fast radio bursts – brief, powerful and mysterious flashes of light. “Because these flashes last only a millisecond, you can’t just go back and look at that patch of sky at a different time and catch that fast radio burst,” Chatterjee said. “You have to be looking at that right millisecond to be able to catch a fast radio burst.” Astronomers now believe that these fast radio bursts, once deemed a rarity, are so common that they light up the night sky roughly twice a minute, Falcke said – and yet, in the near-decade that we’ve known about them, they’ve only managed to catch a total of 18 in the act, let alone figure out where they’re coming from. Chatterjee and colleagues, and the rest of the astrophysics community, are left scratching their heads.” Understanding the nature of fast radio bursts could help researchers probe the intergalactic medium – the nearly empty space between galaxies – and it could shed light on the physical processes that let off the burst in the first place.
