Snow Moon and Planet Jupiter


A dramatic scene in the sky as clouds obscure the snow moon and the planet Jupiter. If you look closely at Jupiter in the right corner, you can also see three of its moons. The light is refracted in the clouds, creating beautiful colors.
When moonlight hits water droplets in clouds or rain, the light is refracted and reflected, splitting the white light into all the colors of the rainbow (red to violet). This optical phenomenon is called dispersion and occurs when light rays pass through the surface of the water droplets, bounce off the back, and are refracted again.

Lonely lingonberry leaves

Many nights with clouds and no photography. But tonight the sky was clear and I went out in the moonlit forest and found this lonely lingonberry leaves sticking up above the snow. They can withstand temperatures down to -45 degrees. This night in the moonlight the temperature is -11 degrees. Lingonberry leaves (Vaccinium vitis-idaea) are known to be rich in substances such as arbutin and proanthocyanidins, which makes them traditionally valuable for urinary tract problems. They can be used as a tea or tincture but should be used in moderation and not during pregnancy or breastfeeding.
Health effects: Lingonberry leaves are often used as a natural home remedy for urinary tract infections, like bearberry leaves. They are also considered to have antioxidant properties.
Uses: Dried leaves can be used to make tea, where 1-3 teaspoons of leaves are brewed in 200 ml of boiling water for 10-15 minutes.

Good seeing watching the moon

Very good view through the telescope when I looked at the moon the other week. At the top is Montes Jura, it surrounds the smooth lava bed Sinus Iridum (Bay of Rainbows) on the northwestern edge of Mare Imbrium (Sea of ​​Rain). A little to the south is the mountain range Montes Recti where the highest peaks reach a height of about 1.8 km (Latin for "Straight Mountains") is a distinctive, linear mountain range on the moon, located in the northern part of Mare Imbrium. Below are the mountains Montes Teneriffa (Tenerife Mountains) with individual peaks at heights of up to 2.4 kilometers. The crater Plato (in Swedish often called Platon) is one of the moon's most famous and easily recognizable impact craters. It is particularly famous for its dark, flat bottom and its location at the edge of one of the large lunar oceans. Plato has one of the darkest surfaces on the moon because it is filled with old, solidified basaltic lava. Astronomers like Johannes Hevelius once called it "The Great Black Lake"

Moonlit snow crystals


97% moon and the bright planet Jupiter next to it. In the cold snowy landscape, small crystals of different colors are seen in the snow taken with a macro lens. Even the two-bright stars Castor and Pollux are seen above the moon.
Snow crystals appear in different colors primarily due to light interference (thin films, prisms) or contamination, with thin-film interference causing iridescent blues, purples, and rainbow hues from light reflecting off layers, while contamination from algae (watermelon snow, green) or dirt/pollen creates vibrant reds, greens, and even blacks, altering the crystal's pure white appearance
