IMAGE experiments have detected the flows of atoms from interstellar
space as they pass through the solar system, and Earth's environment. The two black lines in the figure show the locations of these atoms. The top trace shows the changing directions of the interstellar neutral atoms between 8:00 and 10:00 Ut. The curve in the lower right shows neutral atoms detected in the direction of earth's orbital motion.
