A moonbow is a rainbow caused by moonlight. It’s a bit fainter than an actual rainbow. Moonbows are rare because moonlight is not very bright. A bright full moon is needed & it must be raining opposite the moon. The sky must be dark and the moon must be less than 42º high. (Source) (You may also like: 360 degree rainbows)
The entangled pearl necklaces pictured above are actually droplets of dew on a spider web.
The subtle colors displayed here resulted when sunlight illuminated the web, creating a multitude of rainbow fragments. Note that, in general, the smaller dew drops, residing on the thinnest silk strands, are nearly colorless.
With these smaller drop sizes, wave interference acts to diminish coloration because colors tend to overlap one another.
It is green, itchy and beautiful. It is identified with the desert. It is hard to die, as it lives with only a bit of water that manages to conserve it for long periods of time. Its name is cactus and it makes for a plant different than any other. I used to have one in my balcony; it was supposed to scare people away, which it never managed, but quite on the contrary – every visitor got charmed by my cactus friend.
In a more serious tone, cactus is a plant of particular beauty, and, despite what many people think of it, it also blossoms. The difference with other plants is that when it blossoms it certainly makes for breaking news! Given my passion for cactuses, I found out that Lanzarote might be famous for being an ideal summer destination, but, apart from its fantastic beaches and resorts, it also hosts a unique cactus garden! Don’t forget to keep yourself at a safe distance! They’ll greet in a pinch of a needle!

Ingo Arndt Animal Architecture
“Every day, all over the world, animals and insects set about the purposeful tasks of designing their homes, catching their prey, and attracting their mates. In the process they create gorgeous nests, shelters, and habitats. Capturing 120 of these wonders in all their beauty and complexity, Animal Architecture presents a visually arresting tribute to the intersection of nature, science, function, and design.”
Derweze, also known as the door to hell, is a 70 meter wide hole in the middle of the Karakum desert in Turkmenistan. The hole was formed in 1971 when a team of soviet geologists had their drilling rig collapse when they hit a cavern filled with natural gas. In an attempt to avoid poisonous discharge, they decided to burn it off, thinking that the gas would be depleted in only a few days. Derweze is still burning today
