A very long solar filament that had been snaking around the Sun erupted (Dec. 6, 2010) with a flourish. STEREO (Behind) caught the action in dramatic detail in extreme ultraviolet light of Helium. It had been almost a million km long (about half a solar radius) and a prominent feature on the Sun visible over two weeks earlier before it rotated out of view. Filaments, elongated clouds of cooler gases suspended above the Sun by magnetic forces, are rather unstable and often break away from the Sun.

A jewel of the southern sky, the Great Carina Nebula, also known as NGC 3372, spans over 300 light-years, one of our galaxy's largest star forming regions. Like the smaller, more northerly Great Orion Nebula, the Carina Nebula is easily visible to the unaided eye, though at a distance of 7,500 light-years it is some 5 times farther away. This gorgeous telescopic close-up reveals remarkable details of the region's central glowing filaments of interstellar gas and obscuring cosmic dust clouds. The field of view is over 50 light-years across. The Carina Nebula is home to young, extremely massive stars, including the stars of open cluster Trumpler 14 (below and right of center) and the still enigmatic variable Eta Carinae, a star with well over 100 times the mass of the Sun. Eta Carinae is the brightest star, seen here just above the dusty Keyhole Nebula (NGC 3324). While Eta Carinae itself maybe on the verge of a supernova explosion, X-ray images indicate that the Great Carina Nebula has been a veritable supernova factory. via NASA ift.tt/1ORra3a

An old one from my drive ..Thats the inner part of a incandescent bulb . and ooh the filament is too hot that it will blast ...
Small light bulb next to me flicked on while I was waiting for a burrito. Snapped on the Momentlens macro and faced the setting sun.
Be a lamp, or a lifeboat, or a ladder. Help someone's soul heal. Walk out of your house like a shepherd.

NASA image captured Nov 16-18, 2010
An elongated filament slithered, stretched and curled around the edge of the Sun as SDO watched in extreme ultraviolet light (Nov. 16-18, 2010). At one point it seems to break in two, but then it re-establishes its continuity. A second filament appears in the left part of the video clip and still too, though it is not as large or active. Filaments are relatively unstable clouds of cooler gases suspended above the Sun by magnetic forces. Sometimes they erupt and burst into space; other times they just fade away. Keep an eye on this one!

A magnetic filament snaking around the sun's SE limb just keeps getting longer. The portion visible today stretches more than 700,000 km--a full solar radius. NASA's Solar Dynamics Observatory took the above picture during the early hours of Dec 6, 2010.
So far the massive structure has hovered quietly above the stellar surface, but now it is showing signs of instability. Long filaments like this one have been known to collapse with explosive results when they hit the stellar surface below. Further updates will be posted as warranted.

A imagem capta, em plano de detalhe, uma rã-verde (Pelophylax perezi) camuflada no seu habitat natural em vias de desaparecer.
O anfíbio, de pele húmida com padrões poligonais em tons de castanho, ocre e uma linha dorsal verde-amarelada, encontra-se estático sobre uma densa camada de vegetação aquática.
O meio circundante é composto por pequenas folhas de lentilha-d'água e filamentos entrelaçados que exibem uma tonalidade predominantemente amarelada e dourada, denunciando a escassez de água e o efeito do calor sobre o charco.
No canto inferior direito, vislumbra-se o logótipo circular com o monograma "MS" do autor.

A Última Poça de Sol
O mundo de “Peló”, a rã-verde, media-se outrora pela distância de um grande salto.
Havia dias em que o céu se afogava inteiramente no charco e as suas águas profundas sabiam a lodo fresco e a canções de acasalamento que ecoavam pelas noites fora.
Mas o verão daquele ano trouxera um bafo pesado, um sol tirano que bebia o charco às colheradas, sem pedir licença.
.
Agora, o vasto império de água reduzia-se àquele minúsculo tapete de lentilhas-d'água e musgo entretecido, que o calor começava a pintar com as cores douradas e tristes do outono antecipado.
A água viva, que antes corria livre e límpida, transformara-se numa humidade espessa, num abraço térmico que sufocava a terra.
.
“Peló” mantinha-se imóvel, com o corpo achatado contra a pouca frescura que restava no fundo do leito.
A sua pele, uma obra-prima de camuflagem desenhada com as próprias cores do lodo e das folhas secas, confundia-se perfeitamente com o cenário.
Era uma estratégia de sobrevivência, sim, mas também um ato de comunhão: a rã recusava-se a abandonar a casa que a vira nascer, mesmo quando esta se desfazia em pó.
.
Com os seus grandes olhos dourados e atentos, “Peló” olhava o horizonte ao nível das plantas aquáticas.
Sentia a pele secar milímetro a milímetro.
Sabia que, a pouca distância dali, para lá da barreira de juncos ressequidos, a morte espreitava sob a forma de terra estalada.
Cada vibração gular era uma contagem decrescente; cada raio de sol que atravessava a folhagem era um aviso de que o tempo estava a evaporar-se tão rápido como o líquido precioso.
.
Contudo, na memória ancestral da rã-verde, habitava a promessa das primeiras gotas de outono, o cheiro a terra molhada que faz o chão reviver.
Até lá, “Peló” seria o coração pulsante daquele charco moribundo, a última sentinela que, num silêncio estático, esperava que os céus voltassem a ter misericórdia da sua pequena pátria de lama.
.
E, você, o que acha que aconteceu à pequena rã verde “Peló”?

2/2.-
Vaig entrar a una botiga del poble, són amics. Des de fora havia vist aquest tipus de bombetes de filament. Amb van encuriosir i vaig entrar.
Demanant permís m'hi vaig apropar per poder-les captar.
Suposo que van haver desitjat haver-me dit que no, doncs, amb el meu volum i estret que era abans de poder-m'hi apropar vaig fer trencadissa.
Volia pagar allò que havia trancat, un marc i una llum, no em van deixar.
Amb mi aquella tarda van fer un negoci frustant... Ja he dit que era amics, ara no ho sé ... bé, segurament sí, però no sé si em deixerien entrar, potser amb treurien la peça a fotografiar per no seguir amb la trencadissa.
El meu resultat van estar aquestes dues imatges . És evident que m'interessava pel filament, quasi res més ... potser perqué les actuals bombetes de letz tenen més durada i gasta menys, però per mi els manca l'encant d'altres temps. Que hi puc fer sóc un romàntic però em comporto com un elefant ......
Enormous Solar Prominence captured by STEREO Spacecraft
The twin STEREO spacecraft (called “Behind” and “Ahead” denoting their relative positions in space), now almost 120 degrees apart, captured this large and dramatic prominence eruption over about a 30-hour period between Sept. 26-27, 2009. Prominences, called filaments when they are viewed against the surface of the Sun, are clouds of cooler gas suspended above the Sun’s surface by magnetic forces. This erupting prominence was large enough that both spacecraft were able to observe it for hours on end, one of the first times that has occurred.
From the Behind perspective (on left) the long filament, darker than the Sun’s surface, can be seen rising up and then breaking away, spreading out above most of the Sun’s surface. As seen from the Ahead spacecraft (right), the filament is seen in profile and is therefore called a prominence. The very large cloud lifts up, breaks away, and heads out into space. This is one of the most spectacular eruptive prominences STEREO has observed.

i stood on a stool in the patio of a burger shop and had a twenty-second photo shoot while waiting on one mighty tasty burger. and i actually managed to get the detail on that one bulb's filament without falling on my ass.
MacroMondays-wire
Filament-a conducting wire or thread with a high melting point, forming part of an electric bulb or thermionic valve and heated or made incandescent by an electric current.
2 weeks on the trot I've used bulbs :o) like the reflection in this one.
