A NASA mission is underway to map the heliosphere, which is a huge protective bubble around the solar system that was created by the sun.

NASA’s IMAP spacecraft studies charged particles, energetic neutral atoms, and magnetic fields at the heliosphere’s boundaries, providing real-time space weather data for Earth and spacecraft.
