An Aurora of Marbles
Explanation: It looks like a fine collection of aggies. But this grid of embedded swirls and streaks actually follows the dramatic development of
planet Earth's auroral substorms. The sequence of over 600 horizon-to-horizon fisheye images was taken over a 2 hour period near the artic circle in March of 2012 from Lapland, northern Sweden. It begins at upper left in evening twilight and ends at lower right, covering two activity peaks with bright coronae forming overhead. While exploring space between Earth and Moon, NASA's fleet of
THEMIS spacecraft discovered that these explosions of auroral activity are driven by sudden releases of energy in the Earth's magnetosphere. Even if you're not
playing for keepsies, you can follow this link to check out the sequence in a
full timelapse video (vimeo).

You know, if you look just right at the array of pictures, they can appear in 3D. Just let your eyes relax and it will appear!

Be sure to
Outstanding
Just as zero is not equal to infinity, everything coming from nothing is illogical.

Watching the time lapse video gives the sensation of being a figurine in a snow globe and someone just shook it!

For some reason, we still see this picture instead of Feb 8th APOD.

Yes; the Feb 8th APOD didn't move into production. The editors have been notified, undoubtedly more than once!

The term 'aggies' for marbles is one that I didn't know. I guess it may be that some were made of agates. The marbles I played with as a child were glass and known as taws/tors. The largest ones were known as stonkers and bollys, though there will have been other names that I've forgotten now due to me gradually losing my marbles
.
Intriguing APOD image and a nice video as well.

Anyone notice that it is now February 8th? What happened to today's APOD?
