A giant glow that swept through the solar system in April prompted scientists to conduct extensive investigations in space to reveal the origin of the high-energy explosion.
A group of researchers led by the University of Johannesburg revealed that the explosion, called GRB 200415A, was launched from a magnetic star – a neutron star with a strong magnetic field – located in a spiral galaxy distant from 11.4 million light years.
The elusive visitor passed through Mars in the early hours of April 15 and was picked up by a number of satellites, including the International Space Station, which triggered research outside of the Milky Way and into the distant galaxy NGC 253.
However, the explosion only lasted 140 milliseconds, since advanced orbital devices were able to capture more data than the previous rocket discovered 13 years ago.
GRB 200415A was captured at 4:42 a.m. EST on April 15, via satellite, and was the first known giant rocket detected since 2008 by NASA’s Fermi Gamma Space Telescope.

The latest explosion was also revealed by Fermi, along with Swift, Mars Odyssey, Wind and the European Space Agency’s INTEGRAL satellite.
Gamma-ray bursts (GRBs) are the brightest and most dynamic events in the universe. It can only be detected when the beams are aimed directly at the ground.
Most of them are billions of light years away and can last anywhere from milliseconds to hours when viewed from Earth.
Scientists have known for some time that supernovae emit long bursts of GRB, which are explosions lasting longer than two seconds.
And in 2017, a team decided that two neutron stars were pushing together, which could also emit a short burst of light. The 2017 explosion came from a safe location 130 million light years from Earth.
Professor Swibor Razaki of the University of Johannesburg said: “There are tens of thousands of neutron stars in the Milky Way galaxy. Of these, only 30 are currently known to be magnetic. Magnetic stars emit most x-rays from time to time. But so far we only know. A few magnetic stars have produced gigantic eruptions. The brightest that we could discover happened in 2004. Then the GRB 200415A arrived in 2020. “

And if the next giant rocket (GRB) were to strike near our Milky Way, a powerful radio telescope on Earth like MeerKAT in South Africa might be able to detect it, he says.
It would be an excellent opportunity to study the relationship between high energy gamma ray emissions and radio wave emissions during the second explosion.
