Solar wind - Wikipedia
The solar wind is a stream of charged particles released from the Sun's outermost atmospheric layer, the corona. This plasma mostly consists of electrons, protons and alpha particles with kinetic energy between 0.5 and 10 keV.
What Is the Solar Wind? - NASA Science
2024年11月21日 · Through the solar wind, the Sun touches every part of our solar system. The solar wind’s many impacts include creating auroras and stripping planets’ atmospheres. Here’s a look at where it comes from and how it influences everything from …
Solar wind: What is it and how does it affect Earth? | Space
2022年7月6日 · Solar wind is composed of charged particles and the sun's magnetic field and is continually released from our star. Explore the phenomenon in more detail here.
The Solar Wind - NASA
The solar wind streams off of the Sun in all directions at speeds of about 400 km/s (about 1 million miles per hour). The source of the solar wind is the Sun's hot corona. The temperature of the corona is so high that the Sun's gravity cannot hold on to it.
Solar Wind - NOAA / NWS Space Weather Prediction Center
The solar wind continuously flows outward from the Sun and consists mainly of protons and electrons in a state known as a plasma. Solar magnetic field is embedded in the plasma and flows outward with the solar wind. Different regions on the Sun produce solar wind of …
What is the solar wind? | University of Chicago News
The solar wind is a flow of particles that comes off the sun at about one million miles per hour and travels throughout the entire solar system.
Effects of the Solar Wind - NASA Science
2019年11月24日 · Welcome to the wind that begins in our Sun and doesn’t stop until after it reaches the edge of the heliosphere: the solar wind. The corona is the Sun’s inner atmosphere – the brightness that can be seen surrounding an eclipsed Sun - and home to the continually expanding solar wind.
Solar Wind - NASA Jet Propulsion Laboratory (JPL)
The solar wind is created by the outward expansion of plasma (a collection of charged particles) from the Sun's corona (outermost atmosphere). This plasma is continually heated to the point that the Sun's gravity can't hold it down.
25 Years of Science in the Solar Wind - NASA
2019年11月1日 · For the past 25 years, Wind has been studying the heated gas of charged particles — known as plasma — that fills the space between planets. The observations have allowed scientists to gain an understanding of the solar wind and its interactions with the near-Earth environment.
