EXPLOSÃO SOLAR - Eruptive Solar Prominence

«AIA caught this beautiful prominence eruption only a few days after its doors were opened. The movie wobbles at the end because AIA's image stabilization system wasn't fully activated yet. Without the full stabilization capability, AIA would not be able to see the Sun at such high resolution. The actual wobble was extremely small - imagine a period in a newspaper seen from 100 meters away. Now move that period over a couple of words.»
            «Explanation: Sometimes part of the Sun can just explode into space. These explosions might occur as powerful solar flares, coronal mass ejections, or comparatively tame eruptive solar prominences. Pictured above is one of the largest solar prominence eruptions yet observed, one associated with a subsequent coronal mass ejection. The prominence erupted last month (April 2010) and was recorded by several Sun-sensing instruments, including the recently launched Solar Dynamics Observatory (SDO). The above time lapse sequence was captured by SDO and occurred over a few hours. In recent months, our Sun has becoming increasingly active, following a few years of an unusually dormant solar minimum. Over the next few years our Sun is expected to reach solar maximum and exhibit a dramatic increase in sunspots and all types of solar explosions

Plasma Rain
PLASMA RAIN, April 2010. 
«On April 19, AIA observed one of the largest prominence eruptions in years. The huge structure erupts, but a great deal of the plasma (hundreds of millions of tons) is unable to escape the gravitational pull of the Sun and falls back down as "plasma rain." As the rain impacts the surface, bright flashes can be seen as the momentum is absorbed on impact. SDO is the first observatory to capture both the rain and the impacts, allowing us to learn a great deal from observations like this.»

A Hall of Mountain Fogbows

       «Explanation: If you tried to enter this hall of fog, you would find it dissipates around you. The hall is actually an optical illusion created by sunlight backscattering off of a cloud passing below the peak of the mountain from which this picture was taken. Known as a fogbow and similar in some ways to "the glory", the phenomenon is sometimes seen from airplanes. The ring's center appears near the image bottom where the shadow of the photographer is visible. This shadow would likely change as clouds passed, creating a faux moving giant known as the Brocken Spectre. In the picture, several concentric rings of the fogbow appear to create a hall for this mountain king. The cause of fogbow supernumeraries arcs and glories have only been understood recently and are relatively complex. Briefly, small droplets of water reflect, refract, and diffract sunlight backwards towards the Sun. Atmospheric backscattering phenomena have a counterpart in astronomy, where looking out from planet Earth in the direction opposite the Sun yields a bright spot called the gegenschein.»    Fonte: http://apod.nasa.gov/apod/ap100504.HTML
