Mushroom and Vega

Another clear night with a bright moon. This time, I found a beautiful *Boletus edulis* (porcini mushroom). Below it stands a solitary trumpet lichen fluorescing a vivid blue, while the porcini glows with a greenish hue. *Boletus edulis* is an edible mushroom found in both deciduous and coniferous forests. Technically, it is a bolete. It forms mycorrhizal associations and is therefore dependent on host trees.

In the sky, the bright star Vega is visible in the constellation Lyra.
It lies approximately 25 light-years from Earth, emits a bluish light, and rotates so rapidly that it is flattened into an egg-like or ellipsoidal shape.
Its mass is roughly 2.1 to 2.5 times that of the Sun.
It shines with a luminosity about 40–50 times greater than that of the Sun.
Surrounding the star is a disk of dust and asteroid belts that may indicate the presence of a planetary system.

Fungi & Night Sky

A clear evening in the woods behind my house. Simply walking around looking for beautiful little objects is a pleasure. It is now mushroom season, and many of them fluoresce under UV light. These fungi are vital, acting as nature’s cleanup crew by breaking down dead wood and leaves, thereby returning nutrients to the soil.
What we pick and call a "mushroom" is merely the fruiting body. Beneath the ground lies a vast, intricate network of fungal threads known as mycelium. It is through this mycelium that the fungus absorbs water and nutrients from the soil.
Symbiosis with trees (Mycorrhiza): Many of our most common edible mushrooms live in symbiosis with forest trees. Through underground contact, they exchange services: the fungus provides the tree with water and minerals, while the tree supplies the fungus with sugars (carbohydrates) produced via photosynthesis.
The soil's kidneys: Fungi are extremely efficient at absorbing substances from the soil. Unfortunately, this means they can also take up and store environmental toxins, heavy metals, and radioactive substances (such as cesium) if they grow in contaminated soil.
Visible in the starry sky are the constellations Perseus, Cassiopeia, and Auriga.

 

Blue Trumpet Lichens and starry sky

 

Red clover with a aphids on it a clear night

A clear night and I came across this red clover. I illuminated it with UV light and used a macro/wide angle lens to capture the fluorescent colors and the starry sky. Then I noticed the aphids that were hanging out under the flower. Later I took an even closer look at the flower with a more powerful macro lens 2.5x.

Pine lichen and crescent moon

Fluorescent lichens and moss on a pine tree by illuminating with UV light.

Lichens on trees are usually completely harmless and are not a sign of disease. They only use the tree as a foothold and do not take nutrition from it. The lichens indicate clean air and serve as homes for insects, which attracts small birds.

Key facts about lichens on trees:

No harm: Lichens do not penetrate the bark, do not cause rot and do not harm the growth of the tree.

Epiphytes: They grow as so-called epiphytes, mainly on older trees, and get nutrition from water and air.

Air quality: Abundant occurrence of lichens is a sign of a good air environment.

Common types: Examples are leaf lichens such as lung lichen, beard lichen and crust lichen.

Ecological benefit: Lichens provide habitat for small animals, which benefits bird life.

Where life once evolved.

 A clear and cold night by the sea on planet Earth. In the sky, the constellation Orion is visible with the star factory Orion Nebula under Orion's belt, visible to the naked eye. Our star Sun was probably created from a similar star factory long ago. The Orion Nebula (M42) consists primarily of gas and dust, where the absolutely dominant elements are hydrogen and helium. It is an emission nebula that shines because young, hot stars ionize the gas.

The Earth formed about 4.6 billion years ago from a rotating disk of gas and dust that surrounded the young Sun. By clumping together pebbles and cosmic dust, the planet grew. Originally, the Earth was a red-hot melt that cooled and formed a solid crust. Water was added later, probably via comet impacts. The theory of the origin of life is that life on Earth arose in the ocean about 3.5–3.8 billion years ago, probably in close proximity to hot springs on the seafloor where amino acids and simple bacteria were formed. The ocean served as a protective environment for the first organisms before oxygen and the ozone layer made life on land possible. The oldest traces of life are 3.5–3.7 billion years old and are found in marine environments. Early theories focused on the "primordial soup" in shallow sea bays, while more recent research often points to hot springs (hydrothermal vents) in deep water. Complex organic molecules (amino acids) formed in the water and assembled into simple bacteria. These first organisms were independent of oxygen, but later began to produce it through photosynthesis. Evolution started with simple microorganisms, followed by algae, and later the first multicellular animals developed in the sea. The picture shows algae and seaweed that fluoresce via UV light. They are clearly visible thanks to the current record low sea level. Algae contain chlorophyll for photosynthesis. When chlorophyll is hit by UV light or blue light, it absorbs the energy, but cannot use it all. The excess energy is emitted as a red or pink glow. This is called fluorescence and can often be seen underwater with special lighting or when analyzing algae. Under Orion, light pollution from civilization is seen, life has developed into an intelligent species Homo Sapiens Sapiens that eventually invented electricity. The place where the picture was taken, Nothamn Sweden, is known for its geology, 1.9 billion years ago there were explosive volcanoes here that spewed ash and lava over a shallow sea that covered the area. Early forms of life, microorganisms, lived on the seabed, which together built up limestone layers. Iron precipitated in the limestone and layers of iron ore were formed, something that is common throughout Bergslagen. Deep down, beneath the volcanoes, large magma chambers have solidified into the rocks diorite and gabbro. So the rocks in the picture were created during this time.

Low water level in a icy landscape

The Baltic Sea is currently experiencing historically low water levels. During February 2026, persistent high pressure and strong northeasterly winds pushed enormous amounts of water – almost 300 cubic kilometers – through the Öresund and the Belts towards the North Sea.

Historical levels: Several measuring stations have approached or broken previous records for low water levels.

Cause: A strong and stationary high pressure combined with cold winds has acted as a "pump" that has drained the sea of ​​water.

Good news for the environment: The extremely low water level creates a "place" in the Baltic Sea. When the weather turns, this can pave the way for a strong influx of salt and oxygen-rich water from the Western Sea, which is crucial for saving oxygen-poor seabeds.

So why not head out to the east coast on a starry night! And indeed, the water level was very low. I could see barnacles on the rocks where the water's edge used to be. Amazing ice formations everywhere and when I shone UV light many interesting things under the ice fluoresced in different colors. I have no idea what it was, but probably algae, seaweed and minerals.

And on top of all this beauty the Northern Lights appeared with a nice spectacle!

The lonely pine cone

Finally some starry skies! Orion is beautifully high in the sky with the bright planet Jupiter to its left. Took a walk in the woods and saw this pine cone lying on the ground. Took a close-up of it and the starry sky. The pine cone is the spruce's equivalent of a flower. It acts as a protection for the tree's seeds and reacts to humidity by opening when dry and closing when wet.

Quick facts:

Seed bank: A single pine cone can contain up to 200 seeds.

Maturation: The cones mature during their first autumn and release the seeds during sunny spring and winter days.

Who eats them? Squirrels often gnaw them clean, while woodpeckers wedge them into the bark to get to the seeds.

Cone year: The spruce produces abundant cones about every five to seven years, which is called a cone year.

Lichens with Jupiter and lightpollution

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

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.

Airglow Aurora and Big Dipper

Heavy airglow and faint aurora borealis with the big dipper in the sky.

On planet earth you see fluorescence in water and lichens.

Airglow is a faint emission of light by a planetary atmosphere. In the case of Earth's atmosphere, this optical phenomenon causes the night sky never to be completely dark, even after the effects of starlight and diffused sunlight from the far side are removed. This phenomenon originates with self-illuminated gases and has no relationship with Earth's magnetism or sunspot activity, causing aurorae.

The Big Dipper is an asterism consisting of seven bright stars of the constellation Ursa Major six of them are of second magnitude and one, Megrez, of third magnitude. Four define a "bowl" or "body" and three define a "handle" or "head". It is recognized as a distinct grouping in many cultures. The North Star (Polaris), the current northern pole star and the tip of the handle of the Little Dipper (Little Bear), can be located by extending an imaginary line through the front two stars of the asterism, Merak and Dubhe. This makes it useful in celestial navigation.

 

Ocean's purification plant and night sky

Mussels play a super important role as the ocean's purification plant by filtering enormous amounts of water, combating eutrophication (nitrogen/phosphorus), creating habitats (biodiversity) and providing healthy food for people (protein, vitamins), making them a climate-smart and nutritious resource for a sustainable future in Sweden's aquatic environments and other aquatic environments.

Ecological roles Water purification: Mussels filter plankton and particles, purify the water and combat eutrophication by binding nutrients such as nitrogen and phosphorus. Habitat and biodiversity: Mussel beds serve as protection and substrate for many small animals, which increases biodiversity. Key species in the food web: They connect benthic life with free aquatic life, and some freshwater mussels use fish to disperse their larvae.

Some mussels washed up at the shore a clear night by the coast. Faint Aurora and airglow visible in the sky in this macro widefield photo.

A view from planet Earth

Small Fungus standing and almost looks like stargazing under the night sky. Fungi break down dead organic matter like cellulose and lignin, returning vital nutrients to the soil. Without them, the world would be buried under organic debris. Fungi are major players in the carbon cycle, storing carbon in the soil and helping to regulate the climate. Some fungi have the ability to digest pollutants, helping to clean up the environment. Beautiful planet!
