Magnetic Fields on the Sun will be Studied by SUMI

  On July 5, NASA will launch a mission called the Solar Ultraviolet Magnetograph Investigation or SUMI, to study the intricate, constantly changing magnetic fields on the Sun in a hard-to-observe area of the Sun’s low atmosphere called the chromosphere. SUMI’s instruments are designed to study magnetic fields of the sun’s chromosphere — a thin [continue reading]
