What the Heck Is This?

Hint: Today is May 4, and you all know what that means.

Hint 2: While we normally stick to images involving science, nature or technology, this one is really out there, and it's not even a photo.

Okay, so if you didn't know, May 4 is an "unofficial holiday by "Star Wars" fans to celebrate Star Wars culture and remember the films," according to Wikipedia. If you surf over to Wookieepedia, you'll be told: "May the 4th be with you." The image shows Chewbacca the Wookiee in the cartoon series "Star Wars: The Clone Wars Season Three."

Or, of course, if you knew what the image was, then you knew all this. See the full image below.

So why'd we use an image from a cartoon on a science site? Well, it's hard to discuss the physics of the universe, of space-time, of space travel, and of worlds that are light-years away without thinking of "Star Wars." The fiction was even predictive, as in this recent headline: 'Star Wars' Planet with 2 Suns Challenges Theories.

And, What the Heck, we can do what we want.

Got a strange or interesting photo related to science, nature or technology? What the Heck, send it to me and maybe I'll use it. And you follow me on Twitter or Facebook.
