Solar Dynamics Observatory – First Light Images Apr 2010
By
“First Light” images from NASA’s Solar Dynamics Observatory, a space telescope designed to study the sun.Launched on February 11th from Cape Canaveral.moment SDO’s telescope doors opened, it began beaming back. Richard Fisher, director of the Heliophysics Division at NASA,said SDO will change our understanding of the sun and its processes, which affect our lives and society. This mission will have a huge impact on science, similar to Hubble Space Telescope on modern astrophysics. The suns internal dynamics were the subject of intense interest over the last few years as the normal waxing and waning of solar activity did not follow past cycles as closely as anticipated. The solar minimum of 2008 stretched deep into 2009, raising questions about how well we understand the complex internal dynamics that drive sun spots, solar flares and coronal-mass ejections. Because solar storms can disrupt human technologies, its important to know when we might expect a serious event that could shut down the electrical grid.

As they have found lots of activity going on Sun as Sunspots started reappearing. The Sun erupted with one of the biggest prominences in years. This shot from the SOHO spacecraft on April 13, 2010 at 13:13 UT shows a Coronal Mass Ejection from the Sun’s northeastern limb. The massive plasma-filled structure rose up …
