A CSIRO telescope has found its first 'fast radio burst' from space after less than four days of searching.

The discovery of the new burst, FRB170107, was made by CSIRO's Dr Keith Bannister and his colleagues from CSIRO, Curtin University and the International Centre for Radio Astronomy Research (ICRAR) while using just eight of the telescope's 36 dishes.
FRB170107 came from the edge of the constellation Leo. It appears to have travelled through space for six billion years before slamming into the WA telescope at the speed of light.
The burst's brightness and its apparent distance mean that the energy involved is enormous, making it extremely challenging to explain.

Title: The detection of an extremely bright fast radio burst in a phased array feed survey

(5 additional authors not shown)

We report the detection of an ultra-bright fast radio burst (FRB) from a modest, 3.4-day pilot survey with the Australian Square Kilometre Array Pathfinder. The survey was conducted in a wide-field fly's-eye configuration using the phased-array-feed technology deployed on the array to instantaneously observe an effective area of [Math Processing Error] deg[Math Processing Error], and achieve an exposure totaling [Math Processing Error] deg[Math Processing Error] hr. We constrain the position of FRB 170107 to a region [Math Processing Error] in size (90% containment) and its fluence to be [Math Processing Error] Jy ms. The spectrum of the burst shows a sharp cutoff above [Math Processing Error] MHz, which could be either due to scintillation or an intrinsic feature of the burst. This confirms the existence of an ultra-bright ([Math Processing Error] Jy ms) population of FRBs.
