Veronika Jercic, Ph.D., is a NASA Postdoctoral Fellow at Goddard Space Flight Center in Maryland. She studies structures in the solar atmosphere known as prominences or filaments. Jercic calls them clouds on the sun. These clouds are important to understand stretch through all of sun’s atmospheric layers. Unlike the clouds on Earth, these clouds are much denser, so they're very heavy clouds and colder than the Corona in which they are situated. These clouds occasionally erupt, expelling huge masses of particles and energy into the interplanetary space, which see them as the Northern Lights. These energy masses can also impact satellite transmissions, which negatively affect our technologically driven world. To learn more about the NASA NPP Program, visit https://npp.orau.org/index.html
