is this a timelapse?
So, for #ScienceSunday , curated by +Allison Sekuler, +Robby Bowles, +Rajini Rao and +Chad Haney I have a fun image - a fisheye aurora staggered star-trail shot. :)
Please do me a favor and view this large!
The display of northern lights overhead was beautiful, but with the wide-angle effect of the fisheye lens, it was difficult to get a beautiful display of aurora light everywhere I wanted. I also wanted the stars to pop a bit more, especially because I knew the North Star was in the frame.
I decided not to show a full-on star trail shot here, because the streaks completely overpowered the subtle green hues in the night sky. Instead, I calculated which images to use, having their distance grow exponentially to lead into (or away from) a solid pattern. I then picked the closest image to the equation that was visually pleasing, and stacked the images together using the "lighten" blending mode in Photoshop.
Seven shots in total were used, and the aurora fell in just the right places to leave the center of the spinning stars clearly visible. (although, it's us that are spinning - someone always corrects me!) I've just printed this as a 32"x20" canvas and it looks stunning, the first of many prints I make from my adventures in the Yukon.
I sure hope +Robert Walters sees this image for #StarTrailSunday too!

Looking for fun and easy #ScienceforKids Exploding Milk is so fun! #ScienceSunday
Exploding Milk The past couple of weeks we have been enjoying experimenting with Milk with experiments like Plastic Milk and Crashing Colors. We wanted to take the crashing colors experiment a little bit further and that is just what we did with this…

#ScienceSunday: When a #polarbear wags their head from side to side, it's a sign that they want to play. Adult bears initiate play—which is actually ritualized fighting or mock battling—by standing on their hind legs, chin lowered to their chests, with front paws hanging by their sides.
