Jul 18, 2022 · The origins of space weather can be traced to contortions in the sun's magnetic field, leading to dark blotches, or sunspots, on its surface, according to an article by...
Though space is about a thousand times emptier than even the best laboratory vacuums on Earth, it’s not completely devoid of matter – the sun’s constant outflow of solar wind fills space with a thin and tenuous wash of particles, fields, and plasma.

The Sun is always spewing gas and particles into space. This stream of particles is known as the solar wind. The gas and particles come from the Sun’s hot outer atmosphere, called the corona. These particles from the corona are charged with electricity. The solar wind carries these particles toward Earth at up to a million miles per hour!
Earth has an area of magnetic force activity, called a magnetic field. It is also surrounded by a jacket of gases, called an atmosphere. Our magnetic field and atmosphere act like a superhero’s shield, protecting us from the majority of the solar wind blast. Most of the charged particles crash into Earth’s shield and flow around it. The particles s...
Yes! Sometimes magnetic activity within the Sun causes intense solar storms. The solar wind gets much stronger during these storms. Strong solar winds can be dangerous. During a solar storm, explosions called solar flaresbreak out. Solar flares send tons of energy whizzing through space at the speed of light. Sometimes flares come with huge solar e...
Solar storms happen suddenly, and their effects can reach Earth within minutes. But scientists do make predictions about when solar storms are likely to occur and how strong they will be. You can check the space weather forecast just like you might check the weather forecast. Scientists use information from satellites to predict the solar weather f...
Feb 25, 2022 · The solar wind is created when the heat and pressure from below are more powerful than gravity, and the charged plasma in the corona is able to escape into space along the lines of the Sun’s ...

Space weather begins with the Sun. The Sun gives off electromagnetic energy in many wavelengths, including visible light, radio waves, ultraviolet, high energy X-rays, and more. The Sun also emits a stream of radiation in the form of charged particles (plasma) that make up the solar wind.
Dec 10, 2021 · Quite different from your average terrestrial rain or snow, space weather in our solar system is composed of radiation and particles from the Sun. The Sun is made up of superhot electrically charged plasma, the fourth state of matter.
Apr 16, 2024 · Go behind the scenes with NASA’s Moon to Mars Space Weather Analysis Office, a team monitoring space weather—eruptions of radiation and plasma from the Sun that can wreak havoc on spacecraft and pose dangers to astronauts.
