2024 Total Solar Eclipse: Prediction vs. Reality
2 min read 2024 Total Solar Eclipse: Prediction vs. Reality Image Before/After Before a total solar eclipse crossed North America on April 8, 2024, scientists at Predictive Science Inc. of San Diego aimed to foresee what the Sun’s outer atmosphere, the corona, would look like during totality. The predictions help researchers understand the accuracy of their models of the Sun’s corona, which extends along its magnetic field. A solar eclipse offers a rare opportunity to view the entire corona from Earth, guiding research into how its energy can cause solar…
