The researchers also detected nitrogen and argon, but due to their similarities to Earth’s gas characteristics, they were likely mixed into Earth’s air upon return. The detected helium and neon have gas signatures that differ from Earth’s and may have been carried to the surface of the asteroid by the solar wind.
