Summary:
- NASA's Parker Solar Probe has made a groundbreaking discovery by solving a 70-year-old mystery about the Sun's atmosphere, known as the corona.
- The probe found that the Sun's corona is heated to millions of degrees Celsius, much hotter than the Sun's surface, which is only about 5,500 degrees Celsius.
- This discovery helps scientists better understand the complex processes that occur in the Sun's atmosphere and could lead to improved space weather forecasting, which is important for protecting satellites and astronauts.
