The sun is a dynamic star, made of super-hot ionized gas called plasma. The sun's surface and atmosphere change continually, driven by the magnetic forces| NASA Science
A magnetosphere is the region around a planet dominated by the planet's magnetic field. Other planets in our solar system have magnetospheres, but Earth has| NASA Science
Mapping out this interconnected system requires a holistic study of the Sun’s influence on space, Earth and other planets. NASA has a fleet of spacecraft strategically placed throughout our heliosphere—from Parker Solar Probe at the Sun observing the very start of the solar wind, to satellites around Earth, to the farthest human-made object, Voyager, which […]| science.nasa.gov
On a mission to “touch the Sun,” NASA's Parker Solar Probe became the first spacecraft to fly through the corona – the Sun’s upper atmosphere – in 2021. With every orbit, the probe faces brutal heat and radiation to provide humanity with unprecedented observations of the only star we can study up close.| science.nasa.gov
