« The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of starstuff.”
Carl Sagan, Cosmos, 1980
Its scientific name is from the Greek δρόσος: "drosos" = "dew, dewdrops". Its English name is sundew, from Latin ros solis, meaning "dew of the sun". Both names describe the sweet-smelling, sticky (goo) that comes down the ends of on each flower . This mucilage rolls down the plant, attracting sugar-loving insects day and night. The mucilage has enzymes which digests them so that the plants can get the nitrogen it needs from it. Like all plants, the sundew makes its own food, and just uses insects for nitrogen and other nutrients.
Many thanks for your visit, comments, invites and favs..it is always appreciated.
Happy Friday
A semi abstract rendition of a carnivorous Oblong Leaved Sundew plant (Drosera intermedia) growing in a wetland.
The modified leaves of these carnivorous plants attract and trap insects using sticky red tipped hairs that glisten in the sun (hence the name "Sundew"). Sundews grow in bogs and fens where nitrogen essential for plant growth is typically deficient. The hapless insects once trapped by the plant are digested with enzymes to serve as a source of nitrogen rich nutrition. The modified leaves have a total length (with stalk) of about 1-3 cm. Oblong Leaved Sundew is widely distributed and is native to parts of Europe and the Americas.

Flores de Santa Gemita - 021122 - Enhanced-10
Medicago arabica est une annuelle qui préfère les sols bien exposés, riches en matière organique (prairies alluviales) et en azote (bords de route et terres cultivées). Année après année, ses colonies semblent s'étendre de manière «circulaire», fleurissant dès le mois de mai, resemant généreusement ses gousses épineuses et spiralées, et dépérissant (curieusement) du centre vers la périphérie, un peu avant l'été.
Medicago arabica is annual which prefers the quite exposed grounds, rich in organic matter (alluvial meadows) and nitrogenizes some (edges of road and cultivated grounds). Year after year, its colonies seem to extend in a “circular” way, flowering as of May, resowing its thorny and spiral pods liberally, and decaying (curiously) of the center towards the periphery, a little before the summer.
Blooms June-August, Range; North America , except for the far northern regions.
This plant adds nitrogen to the soil as do all plants in the pea family.
This all white mushroom, known as the Destroying Angel (Amanita sp.), contains a potent toxin (amatoxin) and is extremely poisonous if consumed.
The mushroom is widespread in East North America. It forms a network that is intricately associated with the roots of certain trees and facilitates the uptake of essential nutrients, such as phosphates and nitrogen compounds that would otherwise be unavailable to the host plant ( known as an ectomycorrhizal association).

A fern (Polypodiopsida or Polypodiophyta /ˌpɒliˌpɒdiˈɒfɪtə, -əˈfaɪtə/)[citation needed] is a member of a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers. The polypodiophytes include all living pteridophytes except the lycopods, and differ from mosses and other bryophytes by being vascular, i.e., having specialized tissues that conduct water and nutrients and in having life cycles in which the branched sporophyte is the dominant phase. Ferns have complex leaves called megaphylls, that are more complex than the microphylls of clubmosses. Most ferns are leptosporangiate ferns. They produce coiled fiddleheads that uncoil and expand into fronds. The group includes about 10,560 known extant species. Ferns are defined here in the broad sense, being all of the Polypodiopsida, comprising both the leptosporangiate (Polypodiidae) and eusporangiate ferns, the latter group including horsetails, whisk ferns, marattioid ferns, and ophioglossoid ferns.
Ferns first appear in the fossil record about 360 million years ago in the late Devonian period, but many of the current families and species did not appear until roughly 145 million years ago in the early Cretaceous, after flowering plants came to dominate many environments. The fern Osmunda claytoniana is a paramount example of evolutionary stasis; paleontological evidence indicates it has remained unchanged, even at the level of fossilized nuclei and chromosomes, for at least 180 million years.
Ferns are not of major economic importance, but some are used for food, medicine, as biofertilizer, as ornamental plants, and for remediating contaminated soil. They have been the subject of research for their ability to remove some chemical pollutants from the atmosphere. Some fern species, such as bracken (Pteridium aquilinum) and water fern (Azolla filiculoides) are significant weeds worldwide. Some fern genera, such as Azolla, can fix nitrogen and make a significant input to the nitrogen nutrition of rice paddies. They also play certain roles in folklore.

― Carl Sagan, Cosmos
This photograph was taken after a long period of warm and windless weather as the sun was setting and the moon was rising.
I'm not really sure where the haze came from, but even in the day it had a red / brown tinge to it which made me think of the sort of nitrogen dioxide pollution associated with cars and motorways.
Here the setting sun has exaggerated the color so that even the hills in the background appear to have a red / brown hue to them.
Taken in the early hours of this morning (approx. 3.00am) no wonder I feel tired!
Alarm was set for 1.30 - cloud obscured the skies, but then started to clear. I had already set the equipment up in the garage and then just had to open the door and avoid knocking it all over in the dark.
Not the ideal location as there is quite a lot of light pollution locally, but couldn't face driving to the coast after having been on the road all day. Also wanted to have a decent point of reference in the shots.
This is a composite of about 10 shots and there are at least 5 shooting star trails emanating from the North East Perseids atmosphere entry point. If you zoom in you can see a hint of the green / red colouring (green from Magnesium traces in the debris, red from it burning Nitrogen and Oxygen in the atmosphere).
There was also a very spectacular 'fireball' - of course not where the camera was pointing but low to the east it was very bright, reminded me of that Russian dash cam video.
Great to see - and did seem to be more frequent that previous occasions. Counted about 70 over a 2 and a half hour period.
If you want to try it, the settings over are a good starting point. To work out your exposure use the 600 rule - divide 600 by the true focal length of your lens (so 35mm on full frame 17 seconds, on crop sensor 10 seconds). This will avoid you introducing star trails on individual shots.
Sturdy tripod and shutter release locked down - or interval timer if you camera has one (my 7D Mk II does but would have also introduced more noise and captured less light with the shorter exposure).

SN/NC: Trifolium pratense, Fabaceae Family
The name comes from Latin prātum, meaning meadow, red clover, is a herbaceous species of flowering plant in the bean family, Fabaceae. It is native to the Old World, but planted and naturalised in many other regions. It is widely grown as a fodder crop, valued for its nitrogen fixation, which increases soil fertility. For these reasons, it is used as a green manure crop. Several cultivar groups have been selected for agricultural use, mostly derived from T. pratense var. sativum. It has become naturalised in many temperate areas, including the Americas and Australasia as an escape from cultivation.
Due to its beauty, it is used as an ornamental plant. Red clover's flowers and leaves are edible, and can be added as garnishes to any dish. They can be ground into a flour.
The flowers often are used to make jelly and tisanes, and are used in essiac recipes. Their essential oil may be extracted and its unique scent used in aromatherapy. Trifolium pratense is the state flower of Vermont.

Der Name kommt aus dem Lateinischen „prātum“, was Wiese bedeutet. Rotklee ist eine krautige Blütenpflanze aus der Familie der Hülsenfrüchtler (Fabaceae). Sie ist in der Alten Welt heimisch, wurde aber in vielen anderen Regionen angepflanzt und eingebürgert. Sie wird häufig als Viehfutter angebaut und wegen ihrer Stickstofffixierung geschätzt, die die Bodenfruchtbarkeit erhöht. Aus diesen Gründen wird sie als Gründüngungspflanze verwendet. Es wurden mehrere Sortengruppen für die landwirtschaftliche Nutzung ausgewählt, die meisten stammen von T. pratense var. sativum ab. Sie wurde in vielen gemäßigten Zonen eingebürgert, darunter in Nord- und Südamerika und Australasien, als Ausweichmöglichkeit aus der Kultivierung.
Wegen ihrer Schönheit wird sie als Zierpflanze verwendet. Die Blüten und Blätter des Rotklees sind essbar und können als Garnierung zu jedem Gericht hinzugefügt werden. Sie können zu Mehl gemahlen werden.
Aus den Blüten werden oft Gelee und Kräutertees hergestellt sowie Essiac-Rezepte zubereitet. Ihr ätherisches Öl kann extrahiert und ihr einzigartiger Duft in der Aromatherapie eingesetzt werden. Trifolium pratense ist die Staatsblume von Vermont.

Its home is Europe and Asia, but it has been introduced to North America as well.
The plant prefers dry meadows and soils rich in lime, and low in nitrogen.
Blooms typically in the night, important food source for night flying moths. One flower is opened for three nights and have a strong, pleasant scent.

This image, taken by the NASA/ESA Hubble Space Telescope, shows the colorful "last hurrah" of a star like our sun. The star is ending its life by casting off its outer layers of gas, which formed a cocoon around the star's remaining core. Ultraviolet light from the dying star makes the material glow. The burned-out star, called a white dwarf, is the white dot in the center. Our sun will eventually burn out and shroud itself with stellar debris, but not for another 5 billion years.
Our Milky Way Galaxy is littered with these stellar relics, called planetary nebulae. The objects have nothing to do with planets. Eighteenth- and nineteenth-century astronomers called them the name because through small telescopes they resembled the disks of the distant planets Uranus and Neptune. The planetary nebula in this image is called NGC 2440. The white dwarf at the center of NGC 2440 is one of the hottest known, with a surface temperature of more than 360,000 degrees Fahrenheit (200,000 degrees Celsius). The nebula's chaotic structure suggests that the star shed its mass episodically. During each outburst, the star expelled material in a different direction. This can be seen in the two bowtie-shaped lobes. The nebula also is rich in clouds of dust, some of which form long, dark streaks pointing away from the star. NGC 2440 lies about 4,000 light-years from Earth in the direction of the constellation Puppis.
The material expelled by the star glows with different colors depending on its composition, its density and how close it is to the hot central star. Blue samples helium; blue-green oxygen, and red nitrogen and hydrogen.

This is khun Pornchai (73) in his shop in Bangkok’s Talat Noi, an area of metal workshops. You can’t believe from this photo that his shop actually deals in industrial gases (oxygen, nitrogen, etc).
The shop is filled with old radios, clocks and other antique furniture that he collects as a hobby and is not for sale. It was started by his father, a Shanghai immigrant, about 70 years ago and is today run by khun Pornchai and his two sisters.
Then I biked across the Venlo Heath into the Nature Reserve of western Nordrhein-Westfalen and out again to the millennium-old town of Lobberich. Though it's not far away, I'd never really looked at it and the Beautiful Autumn Day enhanced the town's slow attractiveness.
I should have gone before because one of my classicist heroes was born here: Werner Jaeger ( set1888-1971); fleeing Nazi Germany, he became a foremost American scholar.
Here's Ingenhoven Castle set in the middle of a pretty park with huge fountain in the centre of Lobberich. it was built around 1400 when the town was already half a millennium old. Nineteenth-century wool, silk and velvet industry created wealth and a certain condescension to surrounding villages. Soon Lobberichans were designated as 'Wenkbüll' in the local dialect, meaning: Bag of Wind. Today that epithet is taken in good humor indeed embraced.
After the demise of the wool industry, agriculture became again a mainstay of Lobberich economy. Of course, crop rotation is important. The inset taken on the very edge of town shows a flower of Raphanus sativus, Oilseed Radish, used to absorb the nitrogen left in the soil by other crops. Its visitor - beautifully striped velvety in Gold and Black - is a Hoverfly; I think Parasyrphus, possibly nigritarsis.

This was one of the first shots of the night and unfortunately I missed my focus, I love the colours but the fuzzy stars bug the heck out of me :)
Nitrogen Aurora at 3:50 AM on the mo0rning of April 24, about a half hour before morning astronomical twilight started. Both of my cameras, and my mobile phone, picked this up in this purple color.
The most astounding fact is the knowledge that the atoms that comprise life on Earth the atoms that make up the human body are traceable to the crucibles that cooked light elements into heavy elements in their core under extreme temperatures and pressures. These stars, the high mass ones among them went unstable in their later years they collapsed and then exploded scattering their enriched guts across the galaxy guts made of carbon, nitrogen, oxygen and all the fundamental ingredients of life itself. These ingredients become part of gas cloud that condense, collapse, form the next generation of solar systems stars with orbiting planets, and those planets now have the ingredients for life itself. So that when I look up at the night sky and I know that yes, we are part of this universe, we are in this universe, but perhaps more important than both of those facts is that the Universe is in us. When I reflect on that fact, I look up – many people feel small because they’re small and the Universe is big – but I feel big, because my atoms came from those stars. There’s a level of connectivity. That’s really what you want in life, you want to feel connected, you want to feel relevant you want to feel like a participant in the goings on of activities and events around you That’s precisely what we are, just by being alive…

Some kelp washed up on the beach on Morro Strand State Beach in California.
Kelp (brown algae seaweed) possess gas-filled floats known as pneumatocysts that enable fronds to float on the water surface, maximizing exposure to sunlight and enhancing photosynthesis. The gas content of the pneumatocysts can vary, but are usually filled with a combination of oxygen, nitrogen, and carbon dioxide. Depending on the species, the kelp may contain one large pneumatocyst or several smaller pneumatocysts distributed throughout the kelp.

This red disk-shaped phenomenon, is another member of the TLEs (Transient Luminous Events, happening in the middle and upper atmosphere, above thunderstorms) family and is called sprite halo. Under it, there is a group of, relatively small, sprites. Sprite halo is short-lived (some ms) and its color comes from the same physical process as in red sprites (de-excitation of 1st positive group of mol. nitrogen). Halos appear close to sprite tops (alt. ~80-85 km), over active thunderstorms, like sprites. Sprite halos are usually triggered by -CGs, in contrast to sprites which are related to +CGs (99%). There is also a faint stripe of high clouds in front of the halo. The yellow light is a distant ship.
The event happened over the thunderstorms south of Crete (on the east side of the Medicane on 28/10) as seen from S. Attica during the night of Oct. 28, 2021. Faint parent lightning flash at the bottom, behind a cloud layer, can be seen as well. I've used a Sigma 85 mm lens at f/1.4, for 1/4'' with 51.2k iso.

The northern lights are elementary particle physics, superstition, mythology and folklore come to life. Throughout the ages they have filled people with wonder and fear. They have challenged and inspired scientists and artists. I can certainly add photographers! To see the aurora was an unforgettable experience. Auroras are caused by vast super-heated supersonic collections of smashed atoms, known as solar wind, that enter the earth’s upper atmosphere where they collide with oxygen and nitrogen atoms. These collisions usually take place between 60 & 300 km above ground, causing the oxygen and nitrogen atoms to become electrically excited and to emit light. The result is a dazzling dance of green, blue, white and red light.
This picture shows how oxygen diffuses into a liquid. All the pictures of the sequence are taken under black (ultraviolet) light.
On the left vial a fluorescent compound is kept under pure nitrogen atmosphere. After the cap is removed, the following pictures of the sequence show how the blue light emitted by the compound weakens in the presence of the ambient oxygen. This way it is possible to see how the gas is dissolving and advancing trough the liquid (in the same way a drop of ink would in water). We tend to think that once a recipient is opened, air flows immediately into it, but the fact is that, if no stirring is present, the process is slow and can take several minutes.
The time between the first and last pictures is less than 5 minutes. The high sensibility to oxygen could make this kind of compounds potential oxygen sensors in applications where an oxygen free atmosphere is required. This picture is part of my former research as a PhD. student.

Very early this morning Nick and I and a couple of our coworkers/fellow photography friends headed out to Sunrise, Mt. Rainier. We started our hike up to Mt. Fremont at 2 am and got up there in time to enjoy the night sky for a couple hours before watching an amazing sunrise. Kudos to Gwen for choosing a location with 360 degree views, kudos to Jenn for driving, and kudos to Nick for lending me his powerful head lamp for photos!
I'm never completely happy with my night shots, but I always have fun trying! It was a beautiful and inspiring night.
Shane and I will be heading out soon to install some solar panels ☀. Here’s our plan for the day: Nitrogen purging and donning spacesuit, entering the vacuum, a robotic ride in space, moving the 3-m long arrays packed into tubes, connecting them, watch them unfold, and return. People at NASA have been preparing for these spacewalks for over 1.5 years, the step-by-step instructions are 28 pages, the plan if things don’t behave is… 80 pages. And I’m not even mentioning robotic arms operations or the rest of the Station getting prepped for the upgrade. It is astounding what humans can do with teamwork. Back later tonight, you can watch live and learn more about the spacewalk: blogs.esa.int/exploration/pass-the-solar-array-deploy-tho...
Shane et moi sommes sur le point de sortir de la Station spatiale pour installer ses nouveaux panneaux solaires. Avant ça, nous avons quelques heures de préparation devant nous : désaturation en azote (comme en plongée), enfiler son scaphandre, sortir dans le vide, je vais me faire transporter par un bras robotique attaché par les pieds, en tenant un panneau solaire de 3 m de long, on va le brancher ⚡, le regarder se dérouler, et retourner dans le sas 6h30 plus tard 😎
Les collègues de la NASA préparent cette sortie extravéhiculaire depuis un an et demi. La procédure à suivre pour Shane et moi fait 28 pages, et les cas non-nominaux sont prévus sur 80 pages, juste pour la partie scaphandre et matériel, sans compter le bras robotique ou tout le reste de la station… un beau travail d'équipe. Vous pouvez suivre les préparatifs et la sortie sur esawebtv.esa.int

Blue-Freen Algae Bloom - while quite beautiful, blue-green algae are toxic to small animals and fish.
Algae growth is natural, and some amount of algae is healthy. A lake with no algae would be a dead lake.
But the addition of nitrogen and phosphorus from fertilizers and other pollutants, combined with hot, sunny days, can spell excessive growth.
There is little to nothing I can do as I am not a farmer, but photograpically it was beautiful to see the rich contrast between water and sky
