Solar Wind, Heliosphere & Space Weather: Observation, Measurement & Evidence

The solar wind is a continuous outflow of charged particles from the Sun's corona that fills a vast bubble around the Sun called the heliosphere. Space-weather forecasting supports satellite operations, aviation communication, astronaut safety, navigation, and power-grid planning.

The solar wind is a continuous outflow of charged particles from the Sun's corona that fills a vast bubble around the Sun called the heliosphere.

supported

The corona is hot enough that some plasma escapes the Sun's gravity and accelerates outward along open magnetic field lines.
