Geminga ( ) is a gamma ray and x-ray pulsar source thought to be a neutron star approximately 250 parsecs (around 800 light-years) from the Sun in the constellation Gemini.
Its name, attributed by its discoverer Giovanni Bignami, is both a contraction of Gemini gamma-ray source and a transcription of the words (), meaning "it's not there" in Bignami's native Milanese dialect of Lombard. The name was approved by the International Astronomical Union on 4 April 2022.
