Imagine the Universe!

Detection of the first celestial X-rays

The first rocket flight which successfully detected a cosmic source of X-ray emission was launched in 1962 by a group at American Science and Engineering (AS&E). The team of scientists on this project included Riccardo Giacconi, Herb Gursky, Frank Paolin and Bruno Rossi. This rocket flight detected a very bright source they named "Scorpius X-1" ("Sco X-1" for short), because it was the first X-ray source found in the constellation Scorpius.
