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.

Gee, that cave resembles a human skull.
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.
You're causing me to hallucinate.

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...
