Listen to The Sun! Transforming Heliophysics Data into Sound | NASA
Explore how data about the Sun from NASA's Parker Solar Probe, Magnetospheric Multiscale (MMS) and Wind spacecraft has been transformed into sound with NASA’s Coordinated Data Analysis Web (CDAWeb). Observe how audification can benefit heliophysics data analysis and uncover spectral features that the eyes overlook.
Heliophysics (from the prefix "helio", from Attic Greek hḗlios, meaning Sun, and the noun "physics": the science of matter and energy and their interactions) is the physics of the Sun and its connection with the Solar System. NASA defines heliophysics as "(1) the comprehensive new term for the science of the Sun—Solar System Connection, (2) the exploration, discovery, and understanding of Earth's space environment, and (3) the system science that unites all of the linked phenomena in the region of the cosmos influenced by a star like our Sun."
