Fluorescent limestone in red, calcite, in a folding pattern by the sea. Folding patterns in rocks are primarily created through plate tectonics, where the Earth's crust plates collide and compress the bedrock over millions of years. This process, called folding, occurs when rocks are subjected to enormous pressure and temperature conditions, causing them to bend and fold instead of cracking.
In the sky, the planet Jupiter is seen next to the bright stars Castor and Pollux.
A magical night in the Swedish mountains. It started as a green glow in the north that developed into an arc that then increased in strength and went higher in the sky, finally to the zenith with curving green waves of light. The green glow flashed across the entire sky as if the atmosphere was shaking.
A beautiful view of the coast of Väddö, Sweden. On the ground, algae and seaweed stuck in the ice fluoresce like glittering jewels thanks to UV light. A cold night with beautiful Icelandic scenery and low water. In the sky, the bright star Sirius is also reflected in the water. Sirius, often called the Dog Star, is the brightest star in the night sky with an apparent magnitude of -1.46. Located in the constellation of the Great Dog (Canis Major) and only 8.6 light-years away, it is one of Earth's closest neighbors. It is part of a double star system (Sirius A and B) and is easy to find in the winter sky by extending Orion's belt. The planet Jupiter also shines as a bright star high in the center of the image. To the right, the constellation Orion is visible. Between Orion and Jupiter, our Milky Way galaxy is seen as a faint band.
We live on a beautiful planet.
Let's take care of it and each other - stop these insane wars and misery. It is up to us, the people!
Bright planet Jupiter in the night sky on this clear and cold evening. In the foreground is a birch with lava in different colors as I have used UV light to create fluorescence. Lichens on birch are usually harmless, superficial organisms that use the bark as a base without damaging the tree, often a sign of clean air. Common species include blue lichen and various crust lichens. Lichens do not penetrate the bark, do not cause rot and can benefit biodiversity by offering food to insects. The bright night sky is due to light pollution, caused by excessive or misdirected artificial night lighting, disrupting ecosystems, disrupting the circadian rhythm of humans and animals and obscuring the starry sky. It is a rapidly increasing environmental problem that negatively affects biodiversity, insect and bird migration patterns, and can be counteracted by targeted, warm white lighting, motion sensors and timers
A closer look at cliff and stones in fluorescence, also
lichens. The blue stones are probably fluorite, the orange cliff is feldspar
and golden lichens. Lichens fluoresce in "gold" (yellow/orange) due
to natural pigments like xanthones and atranorin, especially under UV light,
revealing hidden colors not seen in daylight. Feldspars crystallize from magma,
this area was vulcanic 1,9 billion years ago.
In the sky bright planet Jupiter and a lot of airglow, even
some faint aurora borealis.
Feldspar, sometimes spelled felspar, is a group of
rock-forming aluminium tectosilicate minerals, also containing other cations
such as sodium, calcium, potassium, or barium. The most common members of the
feldspar group are the plagioclase (sodium-calcium) feldspars and the alkali
(potassium-sodium) feldspars. Feldspars make up about 60% of the Earth's crust
and 41% of the Earth's continental crust by weight.
Feldspars crystallize from magma as both intrusive and extrusive igneous rocks and are also present in many types of metamorphic rock. Rock formed almost entirely of calcic plagioclase feldspar is known as anorthosite. Feldspars are also found in many kinds of sedimentary rocks.
