Astronomy Picture of the Day -- Cave with Aurora Skylight
NASA ^ | July 22, 2014 | (see photo credit)

Posted on 07/22/2014 4:05:06 PM PDT by SunkenCiv

Explanation: Yes, but have you ever seen aurora from a cave? To capture this fascinating juxtaposition between below and above, astrophotographer Bjargmundsson spent much of a night alone in the kilometer-long Raufarhólshellir lava cave in Iceland during late March. There, he took separate images of three parts of the cave using a strobe for illumination. He also took a deep image of the sky to capture faint aurora, and digitally combined the four images later. The 4600-year old lava tube has several skylights under which stone rubble and snow have accumulated. Oh -- the person standing on each mound -- it's the artist.

Photo is fantastic.

:’) I didn’t like it in the context of APoD, but I’m glad you did!

That looks as if it would make a difficult but very fun jigsaw puzzle.

It really is amazingly spectacular, and the photographer is quite the artist.

I think you’ve struck on a mighty good idea for APoD to make some bucks for the space program!

;-) Here’s hoping that they go for it! Give them a whistle and ask.

Bryan and I like doing jigsaw puzzles.

To: right way right

;’) Oh, everyone knows it’s just an acid flashback. ;’)

That was the first thing I thought of when I first saw this, and right after that, well, never mind...
