Sun Eruption Creates Spectacular Plasma Tentacle

Sun Eruption Creates Spectacular Plasma Tentacle

SDO captured this nicely rounded prominence eruption from March 19, 2011 as a prominence became unstable and erupted into space with a distinct twisting motion.

A NASA spacecraft watching the sun has caught a dazzling view of a solar eruption that launched a vast tendril of magnetic plasma into space.

NASA's Solar Dynamics Observatory recorded the sun tentacle, which scientists call a solar prominence, on March 19 as it erupted into space with a rounded, twisting motion.

The eruption occurred over five hours as SDO watched the sun in the ultraviolet range of the light spectrum, SDO mission scientists said in a statement. The solar observatory watched as the prominence twisted up from the sun and expanded, then became unstable. [Video: Round Eruption From the Sun]
