Scientists reveal source of mysterious radio signal that travelled for 200 million years to reach Earth.

A mysterious radio blast from space detected in 2022 originated in the magnetic field of an ultra-dense neutron star 200 million light years away.
Known as fast radio bursts, or FRB, such brief stellar explosions last just a thousandth of a second but carry enough energy to sometimes outshine even entire galaxies

Radio burst lasted just 2 milliseconds. 
Astronomers have detected thousands of FRBs since the first of its kind was spotted in 2007 but exactly how these flares are launched into space isn’t entirely clear.

A new study published last week in the journal Nature focused on FRB 20221022A, a burst discovered in 2022, to find some answers.

Researchers from the Massachusetts Institute of Technology in the US assessed the FRB’s brightness and estimated that it most likely originated from a neutron star’s magnetosphere, the highly magnetic region immediately surrounding it.
