Un video ritratto del Sole 26.04.13

La NASA ha realizzato un video di tre minuti che raccoglie tre anni di immagini scattate dal telescopio spaziale Solar Dynamics Observatory (SDO).

Lunar eclipses, solar flares, coronal mass ejections and even the transit of Venus can be see.

Nasa point out some of the highlights:

00:30;24 Partial eclipse by the moon
00:31;16 Roll maneuver (where the observatory spins around to calibrate its equipment)
01:11;02 August 9, 2011 X6.9 Flare, currently the largest of this solar cycle
01:28;07 Comet Lovejoy, December 15, 2011
01:42;29 Roll Maneuver
01:51;07 Transit of Venus, June 5, 2012

The SDO captures a shot of the Sun every 12 seconds at 10 different wavelengths although this clip only shows two images a day.
