This is a composite of 25 separate images spanning the period from April 16, 2012, to April 15, 2013. In a video, NASA has also collected three years' worth of such images and set them in a new video.
We all deserve a break from the past week's news. This NASA videocould be just the right thing.
According to the space agency, NASA's Solar Dynamics Observatory(SDO) "captures a shot of the sun every 12 seconds in 10 different wavelengths." The video features images from the past three years, "at a pace of two images per day."
NASA adds:
"There are several noteworthy events that appear briefly in this video. They include the two partial eclipses of the sun by the moon, two roll maneuvers [by the observatory, as it changes position], the largest flare of this solar cycle, comet Lovejoy, and the transit of Venus. The specific time for each event is listed below, but a sharp-eyed observer may see some while the video is playing.— "00:30;24 Partial eclipse by the moon— "00:31;16 Roll maneuver— "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— "02:28;13 Partial eclipse by the moon"
