High energy radiation thumb|upright=1.1|right|alt=An X-ray image of η Carinae from Chandra X-Ray Observatory |X-rays around η Carinae (red is low energy, blue higher) Several X-ray and gamma ray sources have been detected around η Carinae, for example 4U 1037–60 in the 4th Uhuru catalogue and 1044–59 in the HEAO-2 catalog. The earliest detection of X-rays in the η Carinae region was from the Terrier-Sandhawk rocket, followed by Ariel 5, OSO 8, and Uhuru sightings.
