The Best in Science News and Amazing Breakthroughs
A particularly bright flash of radio waves that has been traveling through the Universe for more than 8 billion years is proving difficult to explain using current leading theories.Not only has it journeyed considerably further than most FRBs on record, it is incredibly energetic – exceeding the maximum set by previous models by a factor of 3.5.
The forces involved would explain why FRBs blast with the energy of hundreds of millions of Suns in a mere blink of the eye. Yet it also sets a limit on the light's intensity, a limit this latest example exceeds. While the researchers rethink the ways FRB 20220610A and other unusually energetic FRBs might form, the observation is also defying a completely different set of expectations involving the way its light appears to spread through intergalactic space.
Similarly, the gas and dust that floats through the interstellar and intergalactic vacuum carries its own faint electromagnetic buzz that causes wavelengths to slow at different rates as they shine through.

Astronomers detect most distant fast radio burst to dateAn international team has spotted a remote blast of cosmic radio waves lasting less than a millisecond. This 'fast radio burst' (FRB) is the most distant ever detected. Its source was pinned down by the European Southern Observatory's (ESO) Very Large Telescope (VLT) in a galaxy so far away that its light took 8 billion years to reach us.
