Since the beginning of time, man has yearned to destroy the sun.

The Sun is feisty. Rising and falling packets of ionized gas (called plasma) below its surface generate fierce magnetic fields, which store vast amounts of energy. This can give rise to such features as sunspots, explosions like flares and coronal mass ejections, and huge, towering plumes of plasma called prominences. While observing the Sun yesterday, April 29, my pal and friend of the BA Blog Alan Friedman captured an amazing sequence of shots of an eruptive prominence, one that doesn’t simply fall back down to the solar surface, but also blasts material out into space: [Click to greatly enfilamentate.

Hidden Boundaries Of Sunspots Pump Out Plasma Into Interplanetary Space

Academics / General Science : Science Daily (6 years ago)

Complicated networks of magnetic fields power the sun's atmosphere and create both the beautiful structures and violent explosions that scientists study. Active regions, anchored in sunspots, are areas of the sun where the concentra... Read Post

Look At This: A Rainbow, Magnetic Twister on the Sun

Academics / General Science : 80beats (2 years ago)

This vivid twist represents a solar cyclone, made of plasma, or ionized gas, moving along swirling magnetic fields on the Sun. It is a computer simulation of the storms on the Sun, created using data from a space telescope at NASA’s... Read Post

Hot plasma explosions inflate Saturn's magnetic field

Academics / General Science : Science Daily (4 years ago)

A new analysis based on data from NASA's Cassini spacecraft finds a causal link between mysterious, periodic signals from Saturn's magnetic field and explosions of hot ionized gas, known as plasma, around the planet. Read Post
