Coronal mass ejections (or CMEs) are huge bubbles of gas threaded with magnetic field lines that are ejected at high speeds (millions of miles per hour) from the Sun over the course of several hours. If a CME collides with the Earth, it can excite a geomagnetic storm that can damage spacecraft, cause electrical power outages, and endanger astronauts.
