Erste Videos vom Solar Dynamics Observatory

Am 11. Februar 2010 hat die NASA einen speziellen Satelliten zur Erforschung der Sonne ins All geschossen und auf der Webseite der Solar Dynamics Observatory-Mission angekündigt, dass wir die Sonne wie niemals zuvor zu sehen bekommen. Auf dem YouTube-Channel des SDO gibt es nun erste Videos.


YouTubeDirekteruption (am besten in HD und Vollbild schauen)

"AIA caught this beautiful prominence eruption only a few days after its doors were opened. Soon after the instruments opened their doors, the Sun began performing for SDO with this beautiful prominence eruption. This AIA data is from March 30, 2010 [...] This extreme ultraviolet emission line is from singly ionized Helium, or He II, and corresponds to a temperature of approx. 50,000 degrees Celsius."


YouTubeDirektmagneticfields

"This movie [...] shows the Sun's magnetic field followed by only four of SDO's 12 imaging wavebands. You'll see an eruption, flare, and dimming (dark regions evacuated by the eruption) by observing the event in several different layers of the atmosphere."


YouTubeDirektmagnetogram

"This movie starts with a magnetogram from HMI and moves on to 7 different wavebands observed by AIA's telescopes. AIA covers a wide range of temperatures and will answer important questions about the temperature and energy structure of the Sun's atmosphere."
