There was so much amazing beauty in last weekend's aurora. Also some cool science. I believe the curved lines in the green aurora on the right hand side of this all sky image are called "auroral dunes" and are a rare phenomenon. #aurora #dunes #NewZealand

More #Strandbeests from conceptual artist-engineer Theo Jansen. He became obsessed with designing moveable sculptures that might help conserve beach dunes, then says the project got completely out of hand from there. And it's wonderful.

From https://www.strandbeest.com/ Strandbeests are "Skeletons made from yellow plastic tube (Dutch electricity pipe), are able to walk and get their energy from the wind."

to September 2014 and a peaceful wander in the sand dunes, when monsoon clouds helped to keep the temperatures tolerable. A strong wind blew fine sand over the ridges. I love the subtle tones and colors of this moment.

Ingenuity’s View of Sand Ripples During Flight 70

The smooth, relatively featureless terrain proved difficult for the helicopter’s navigation system to track during the fatal Flight 72.

Happy Birthday, White Sands!

On this day in 1933, White Sands was established as a National Monument (it is now a National Park, re-designated in 2019).

Depending on the time of day and weather, the reflective gypsum crystals of the dunes appear to be beige, pure white, cool blue... we couldn't get enough of it during our 2019 road trip in March. :) (blog archive: https://www.alex-kunz.com/tag/road-trip-march-2019/)

#ThrowbackThursday to 2014 and an archive find from Algodones Dunes...

I got quite excited about this photo, developed it to my liking, and then wondered how I missed it back then — only to find out that I had already picked a horizontal orientation version for my portfolio. 🤪

A local herder with his Bactrian camels crossing the dunes of the Gobi desert in Mongolia in beautiful morning light. I spent a few days here earlier this year.
