Help uncover Earth's magnetic shield in space. The Sun constantly sends out energy and streams of charged particles, known as the solar wind. These bursts can be powerful—and sometimes risky—for people and technology on Earth. But Earth has a remarkable defense system. It's called the magnetosphere, an invisible barrier shaped by our planet’s magnetic field. It pushes away most of the Sun’s solar wind as it rushes through space. This protective shield plays a major role in keeping Earth safe from the Sun’s intense space weather, making our planet a much more secure place to live. That’s it's often referred to as a “space umbrella” — it helps protect Earth from the Sun’s space weather.
NASA has created a wonderful program to support mad scientists like us in monitoring solar wind as it impacts impinges impacts the Earth's magnetosphere. To learn more about this effort and get involved, check out NASA's Space Umbrella Program here.
