Stunning Video: 3 Years Of The Sun In 3 Minutes
Originally published on Thu April 25, 2013 8:37 am
We all deserve a break from the past week's news. This NASA video could 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."
"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"
Update at 12:10 p.m. ET. The Music:
We've called NASA to confirm, but it appears the music is by violinist Martin Lass — "A Lady's Errand of Love." Our thanks to "bouwe schmidt crans" who posted that suggestion in the YouTube comments thread of NASA's video.
