NASA`s IRIS Spots Nanojets
(WorldNews Japan)

In a paper published today in Nature Astronomy, researchers report the first ever clear images of nanojets -- bright thin lights that travel perpendicular to the magnetic structures in the solar atmosphere, called the corona -- in a process that reveals the existence of one of the potential coronal heating candidates: nanoflares. In pursuit of understanding why the Sun`s atmosphere is so much hotter than the surface, and to help differentiate between a host of theories about what causes this heating, researchers turn to NASA`s Interface Region Imaging Spectrograph (IRIS) mission. IRIS was finely...
