NASA | IBEX: Observing the Sun's Horizon

The video discusses NASA's IBEX mission, which studies the boundary of the solar system using energetic neutral atoms (ENAs). Unlike traditional telescopes, IBEX captures images from particles, revealing insights about the heliosphere's structure and the interstellar medium. Key discoveries include a ribbon of ENAs at the solar system's edge and differences in local interstellar material compared to the sun. IBEX also contributes to understanding Earth's magnetosphere and solar wind interactions with the moon.
