space sounds

White text on a dark, textured background presents a sequence of informational statements about sound in space, explaining that while space is a vacuum, sound exists as electromagnetic vibrations, which have been recorded by NASA's Voyager, INJUN 1, ISEE 1, and HAWKEYE probes using plasma wave antennas, with the recorded sounds resulting from interactions of charged particles from the solar wind, ionosphere, and planetary magnetosphere.
