I arrived early in the morning to the walkway by Smuggler's Notch to find the whole area engulfed by a void of fog. I was exploring around and shooting some reflections of the trees in a nearby pond when I suddenly noticed the fog was slowly receding, revealing the amazingly colorful foliage on the hills.

Jupiter looks a bit different in ultraviolet light. To better interpret Jupiter's cloud motions and to help NASA's robotic Juno spacecraft understand the planetary context of the small fields that it sees, the Hubble Space Telescope is being directed to regularly image the entire Jovian giant. The colors of Jupiter being monitored go beyond the normal human visual range to include both ultraviolet and infrared light.

Chuvaeva decided to journey to the offbeat dwelling, known as the Casa do Penedo, and this image is the result of her effort. “Even if I got lost a few times, I can say that it was definitely worth it,” she writes. “There was something mysterious in that boulder house, and I took photos of it for a few hours.”
