An international team of astronomers have performed photometric and spectroscopic observations of a Type Ibn supernova, known as SN 2023fyq. Results of the observations campaign, published May 7 on the pre-print server arXiv, indicate that the supernova experienced a long-lasting precursor activity, including pre-explosion outbursts.

NASA's Fermi mission sees no gamma rays from nearby supernovaA 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.
