STEREO Captures Largest Prominence Eruption in 15 Years
The STEREO (Ahead) spacecraft caught this spectacular eruptive prominence in extreme UV light as it blasted away from the Sun (Apr. 12-13, 2010). This was certainly among the largest prominence eruptions seen by either the STEREO or SOHO missions. The length of the prominence appears to stretch almost halfway across the sun, about 500,000 miles. Prominences are cooler clouds of plasma that hover above the Sun’s surface, tethered by magnetic forces. They are notoriously unstable and commonly erupt as this one did in a dramatic fashion. The video clip shows about 19 hours of activity.

I've always believed (with intuition) that 99.99% of any climate change the earth experiences is due to the changes in output from the sun.
The second law of Thermodynamics states that ENTROPY (or the DISorganization of energy and matter) is always increasing. This means, without any outside stimulus, the earth would eventually lose its energy. The only way to FIGHT entropy or for anything to move from a less organized state, to a more organized state is to steal the disorganization from another isolated system.
On earth, plants grow because they can harness the always increasing entropy from the sun. Of course any energy system on the planet follows suit, ESPECIALLY weather and climate.
So as the Sun's output of energy increases and decreases at various stages, it's certain to contribute to the climate, temperature, and overall energy available for earth's systems. Just a though, not trying to start a controversy here. But it is very true that the one system our planet uses to decrease its entropy is the increased entropy of the sun!

Solo dopo queste immagini ci possiamo spiegare le follie che l'umanità sta compiendo in questi giorni. Proviamo a calmarci tutti se non vogliamo concorrere alla nostra distruzione. Il Sole poverino ha i suoi problemi e scaricandoci addosso miliardi di particelle non ci migliora certo. Sta a noi capire e resistere, resistere anche ai suoi attacchi. Giorgio Biuso, Roma
