NASA IRIS Data Reveals Incredible Plasma Bombs in the Sun's Atmosphere

Scientists recently unlocked more of the Sun's secrets as NASA's solar observation satellite, IRIS (Interface Region Imaging Spectrograph), gathered new information about never before seen dynamic solar activity.

IRIS picked-up solar phenomena including nanoflares and plasma bombs that gave scientists significant knowledge about the workings of the Sun. A NASA team studied these hot plasma bombs produced when the Sun converts magnetic energy to thermal energy, according to team leader Hardi Peter from the Max Planck Institute for Solar System Research.

These massive amounts of thermal energy heat up concentrated plasma inside the Sun and reaches up to 180,000 degrees Fahrenheit. Peter describes the bombs as superheated pockets of plasma exploding upward. The bombs are disseminated into the Sun's corona where it cools back and descends into the atmosphere. 

IRIS also demonstrated that high energy particles from nanoflare events greatly influence the chromosphere and the corona that comprises the Sun's outer atmosphere.

NASA says this new information will pave the way for scientists to understand and study more intensively the inner workings of the Sun and how it transfers energy via its atmosphere.

These new findings show the Sun is apparently more complex than previously known, said Jeff Newmark of NASA's Heliophysics Division. He says some regions of the Sun are more complicated than scientists first thought.

NASA, however, is consolidated IRIS' data and observations from the Heliophysics missions will achieve more breakthroughs in solar research. These findings were published in five different studies in a special edition of the journal, Science.
