The solar wind, a stream of charged particles flows at 447 km/s (1 million mph), and while the magnetic field protects us,some particles still cause auroras and geomagnetic storms. | Science Of The Universe

The solar wind – a constant stream of particles and energy flowing from the Sun – was first theorized 65 years ago. But that doesn’t mean scientists have uncovered all its secrets. In fact, a fresh look at data from 12 NASA spacecraft is giving scientists a new perspective. Scientists have long known there’s a lot of variability in the solar wind. Some days huge bursts of particles are released by solar flares, and other days there can be little activity. But how does the solar wind behave on av
