    Life on Earth depends on the Sun. Here are just a few reasons why: 1. The Sun’s gravity holds our entire solar system together. Our solar system is even named after the Sun (the Latin word for Sun is “sol”). 2. Heat from the Sun makes Earth warm enough to live on. 3. Without light from the Sun, there would be no plants or animals—and, therefore, no...

    A spacecraft would easily burn up if it tried to fly into the Sun. However, NASA’s Parker Solar Probe is flying closer than any other robotic explorer ever has. It will be flying inside the Sun’s atmosphere, or corona. This spacecraft will help us learn more about how the Sun works and how solar activitystarts. This helps us to be more prepared!
