A nearby supernova in 2023 offered astrophysicists an excellent opportunity to test ideas about how these types of explosions boost particles, called cosmic rays, to near light-speed.
But surprisingly, NASA 's Fermi Gamma-ray Space Telescope detected none of the high-energy gamma-ray light those particles should produce.
New simulations and models based on this event will help astronomers home in on the mysterious sources of the universe's cosmic rays.
Additional observations of SN 2023ixf at other wavelengths, new simulations and other studies of other young supernovae will help.
The Fermi Large Area Telescope has captured the event at a time of more than 100 years old .
