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. […]
On April 8, 2024, the Moon’s shadow swept across North America, treating millions to a breathtaking view of a total solar eclipse. As the Moon passed in front of the Sun, it revealed the Sun’s wispy white outer atmosphere the corona. Pictures of total solar eclipses are beautiful they capture a moment happening […]
The April 8, 2024, total solar eclipse will produce stunning views across North America. While anyone along the eclipse path with a clear sky will see the spectacular event, the best view might be 50,000 feet in the air, aboard NASA’s WB-57 jet planes. That’s where a trio of NASA-funded teams are sending their scientific […]
Our Sun, like many stars, is adorned with a crown. It’s called a corona (Latin for “crown” or “wreath”) and consists of long, thread-like strands of plasma billowing out from the Sun’s surface. The powerful magnetic field of the Sun defines these strands, causing them to ripple and evolve their structures constantly. The strands are […]
A NASA-funded team of scientists has discovered long-lasting radio signals emanating from the Sun that are similar to those associated with auroras – northern and southern lights – on Earth. Detected about 25,000 miles (40,000 km) above a sunspot – a relatively cool, dark, and magnetically active region on the Sun – such radio bursts […]
