It is clear to everyone that astronomy at all events compels the soul to look upwards, and draws it from the things of this world to the other.

Researchers Pinpoint A Non-Repeating FRB To Within A Few Light Years

Universe Today - Thu, 08/28/2025 - 3:04pm

Fast radio bursts (FRBs) are some of the most powerful signals in the universe. They can emit as much power in a few milliseconds as our Sun does in several days. Despite their strength, we still don’t have a definitive answer to what causes them. That is partly because, at least for the ones that only happen once, they are really hard to point down. But a new extension to the Canadian Hydrogen Intensity Mapping Experiment (CHIME) might provide the resolution needed to determine where non-repeating FRBs come from - and its first discovery was one of the brightest FRBs of all time, which helped researchers track it with an unprecedented level of precision, as described in a new paper in The Astrophysical Journal Letters.
