Solar Corona & Wind Explorer

An interactive heliosphere — the kind of view the PUNCH mission was built to capture

PUNCH-style heliosphere view

Drag the Solar cycle slider from minimum to maximum and watch the magnetic structure reorganize: large polar coronal holes and sparse loops at minimum, a busy streamer belt at maximum. The fast wind (from the poles) and slow wind (from the equatorial streamer belt) stream outward and accelerate as they go. Toggle the transverse Alfvén waves rippling along the open field lines, and cycle the Filter button through false-color looks the way you would flip between SDO/AIA passbands.
