The first radio explosion found in the Milky Way is now repeated when a neutron star with a magnetic field 32,616 light-years away travels through a magnet.
The first lightning bolts of energy were first detected in April, and scientists identified two more, confirming that rapid radio explosions ’emit magnets over distances in the universe’.
A team working with the Westerbrock Telescope in the Netherlands captured the signal, which came in two short bursts, one millisecond long and 1.4 second apart.
Bursts are not emitted with the same force, indicating that magnets have more than one process capable of generating rapid radio explosions.

The first lightning bolts of energy were first detected in April, and scientists identified two more, confirming that rapid radio explosions ’emit magnets over distances in the universe’.
Fast radio explosions (FRBs) are nigo, short pulses, the origin of which is not clear, but scientists are studying space along the path to Earth using this energy.
The nearest source to an explosion discovered to date is the studying magnet, or ‘SGR 1935 + 2154’ – the next galaxy to be 490 million light-years away.
Telescopes in Canada and the United States observed the first eruption in our galaxy in April.
Two or four European radio telescopes, recently discovered by Chalmers University of Technology, point to the SGR 1935 + 2154.
A team working with the Westerbrock Telescope in the Netherlands captured the signal, which came in two short bursts, one millisecond long and 1.4 second apart.
One is in the Netherlands, the other in Poland, and the Onsala Space Observatory in Sweden.
Telescopes observe the neutron star every night for more than four weeks after April.
Mark Snelders, a team member at the Anton Panneko Institute for Astronomy at the University of Amsterdam, said: ‘We do not know what to expect. Our radio telescopes could only see radio explosions very quickly, and this source seems to be doing something completely new. We expected to be surprised! ‘
After logging 522 hours of observation, a small team of telescopes in the Netherlands received a ‘dramatic and unexpected signal’.
Kenzi Nimmo, an astronomer at the Anton Panneko Institute for Astronomy and Astronomy, said: ‘We saw two explosions clearly and very close in time.’
Like the flash we saw from the same source on April 28th, it looks like the fastest radio we’ve ever seen exploding in the distant universe, only dimmed. The two explosions we discovered on May 24 were even lighter. ‘
The remnants of some supernova explosions are so dense that they are surrounded by very strong magnetic fields, which occasionally emit radiation and, in the form of normal gamma and X-rays, decay.
Experts speculate that magnets have a vast body of energy that can transmit rapid radio explosions that can be emitted directly from the surface of a star – the ‘starwake’ or magnetic field.

Jason Hessles, of the Anton Panneko Institute for Astronomy, and Astron in the Netherlands said: ‘The brightest light from this magnet is ten million times brighter than the faint.
‘We asked ourselves, would this be true of high-speed radio explosion sources outside our galaxy?
‘If so, the universe’s magnets generate beams of radio waves that can always transcend the universe – many of which can fall within the range of a moderate – sized telescope like ours.’
Researchers are interested in rapid radio explosions, and can reveal more about the parts of the universe that they travel through before they reach Earth, not only in their origin.
The team plans to point the team of radio telescopes at SGR 1935 + 2154 and other nearby magnets to find out how these intense stars conduct short bursts of radiation.
Franz Kirsten, an astronomer at the Onsala Space Observatory in Chalmers, who spearheaded the project, said: ‘Fireworks from this amazing and nearby magnet have given exciting indications of how fast radio explosions can be created.’
‘The explosions we discovered on May 24 could cause dramatic disturbances near the surface of the star’s magnetic field.’
‘Other explanations, such as causing more impact from magnetism, seem unlikely, but I’m happy to be proven wrong.’
‘Whatever the answers, we can expect new dimensions and new surprises in the coming months and years.’
