NASA's latest Picture of the Day presents an unprecedented view of the solar corona, offering a unique glimpse into the dynamic outer atmosphere of the Sun. In a visually stunning composite image, the ...

The sun’s wispy upper atmosphere, called the corona, is an ever-changing jungle of sizzling plasma. But mapping the strength of the magnetic fields that largely control that behavior has proved ...

The Sun is a magnetized star. Its magnetic field is essentially three dimensional and it occupies all layers of the solar atmosphere. However, routine measurements of the solar magnetic field have ...

The Parker Solar Probe has become the first spacecraft to fly through the Sun's upper atmosphere or corona, NASA announced. In April, it passed within 15 solar radii (around 6.5 million miles) from ...

In a new study published in The Astrophysical Journal, a researcher from The University of Alabama in Huntsville (UAH), a part of the University of Alabama System, explores critical aspects of a ...

The Sun’s inner corona appears greenish in this image taken on 23 May 2025 by the ASPIICS coronagraph aboard Proba-3, ESA’s formation-flying mission capable of creating artificial total solar eclipses ...
