NASA 's Fermi gamma-ray space telescope has examined what may have been the most powerful explosion since the Big Bang .
The BOAT may be the result of matter and antimatter particles annihilating at 99.9% the speed of light.
The explosion was first seen on Oct. 9, 2022 , by NASA and the Neil Gehrels Swift Observatory.
An event as powerful and bright as the BOAT would be visible in the sky over Earth once every 10,000 years .
It's possible the spectral feature the team saw in the BOAT comes from electrons and their antimatter equivalents, positrons, annihilating.
If the team is right, the particles must have been traveling at around 99.9% of the speed of light before they annihilated each other.
The research was published on Friday ( July 26 ) published in the journal Science .
