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 […]

On March 25, 2024, a citizen scientist in the Czech Republic spotted a comet in an image from the Solar and Heliospheric Observatory (SOHO) spacecraft, which has now been confirmed to be the 5,000th comet discovered using SOHO data. SOHO has achieved this milestone over 28 years in space, even though it was never designed […]

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 […]

After 16 years studying Earth’s highest clouds for the benefit of humanity – polar mesospheric clouds – from its orbit some 350 miles above the ground, NASA’s Aeronomy of Ice in the Mesosphere, or AIM, mission has come to an end. Initially slated for a two-year mission, AIM was extended numerous times due to its […]

The cosmos comes alive in an all-sky time-lapse movie made from 14 years of data acquired by NASA’s Fermi Gamma-ray Space Telescope. Our Sun, occasionally flaring into prominence, serenely traces a path through the sky against the backdrop of high-energy sources within our galaxy and beyond. “The bright, steady gamma-ray glow of the Milky Way […]

In December 2022, NASA’s MAVEN (Mars Atmosphere and Volatile EvolutioN) mission observed the dramatic and unexpected “disappearance” of a stream of charged particles constantly emanating off the Sun, known as the solar wind. This was caused by a special type of solar event that was so powerful, it created a void in its wake as […]
