The huge flares passing over Mars originated from a powerful neutron star, 11.4 million light-years away from Earth, in a Milky Way.
- In April, NASA satellites found a huge flare while scanning over Mars
- Scientists say it comes from a powerful neutron star, 11.4 million light years away
- This is the highest outbreak detected by NASA satellites since 2008
- It was called GRB 200415A and lasted for milliseconds, but the updated instrument was able to capture enough data to trace the path back to its source
The huge flares that swept across the solar system in April prompted scientists to explore deep into space to discover the origin of the high-energy explosion-the hunt is finally over.
A team of researchers led by the University of Johannesburg revealed that the explosion called GRB 200415A was released from a magnetar (neutron star with a strong magnetic field) in a spiral galaxy 11.4 million light-years away.
The elusive tourist flew to Mars in the early morning of April 15th, which was captured by many satellites including the International Space Station, which triggered a search for NGC 253 outside the Milky Way and a distant galaxy.
However, the explosion only lasted 140 milliseconds, but because advanced orbital instruments were able to capture more data than flares detected 13 years ago.

GRB 200415A was received by the satellite at 4:42 AM Eastern Time on April 15 and was the first huge flare detected by NASA’s Fermi Gamma-ray Space Telescope since 2008.
Fermi and Swift, Mars Odyssey and Wind mission satellites and the European Space Agency’s INTEGRAL satellite have also detected the recent explosion.
Gamma-ray bursts (GRB) are the brightest and most active events in the universe.
These can only be detected when the beam is pointed directly at the earth.

Most of these occur in places billions of light-years away, and may last from a few milliseconds to a few hours when viewed from the earth.
Scientists have known for some time that supernovae spew out long GRBs with an explosion time of more than 2 seconds.
In 2017, a team determined that two rotating neutron stars can also emit short-lived GRBs.
The cause of the 2017 outbreak was 130 million light-years away from the safety of the earth.
The researchers first thought this was a short gamma-ray burst, but after further investigation, they determined that it was from a magnetar.
Professor Soebur Razzaque from the University of Johannesburg said: “In the Milky Way, there are thousands of neutron stars.”
“Of these, only 30 are known to be magnetars.”
The magnetism is a thousand times higher than that of ordinary neutron stars.
“Most people give out X-rays from time to time. But so far, we only know a few magnetars that produce huge flares. The brightest we can detect is 2004. “
“Then GRB 200415A will arrive in 2020. ”
He said that if the next huge flare GRB occurs closer to our Milky Way galaxy, powerful radio telescopes on the ground, such as MeerKAT in South Africa, may be able to detect it.
“This will be an excellent opportunity to study the relationship between the very high-energy gamma-ray emission and radio wave emission in the second explosion. This will tell us more about what is valid and invalid in our model. “
