A Macro Mondays submission in the topic "contained". This glowing filament of a small incandescent light bulb is contained within its glass enclosure.

Its little Ether Hood
Doth sit upon its Head —
The millinery supple
Of the sagacious God —
Till when it slip away
A nothing at a time —
And Dandelion's Drama
Expires in a stem.
Emily Dickinson (1879)
A close-up look at the gill filaments of a great white shark.
As water passes through the gills, oxygen is absorbed and passed to the shark's deoxygenated blood which is then circulated throughout the shark's body. Carbon dioxide is also passed out from the blood during the process.
A great white shark relies on what is known as ram ventilation, in which the shark must continually be swimming forward to force water through its gills.
Some sharks and rays are capable of buccal pumping in which they can pump water through their gills using the muscles around their mouths, so they don't not have to maintain forward motion in order to breathe.
Peace lilies (Spathiphyllum) are evergreen herbaceous perennial plants with large leaves 12–65 cm long and 3–25 cm broad. Although it is called a "lily", the peace lily is not a true lily from the family Liliaceae. True lilies are highly toxic (poisonous) to cats and dogs, but the peace lily, spathiphyllum is only mildly toxic to humans and other animals when ingested.

An international team of scientists have used data collected by the NASA/ESA/CSA James Webb Space Telescope to detect a molecule known as the methyl cation (CH3+) for the first time, located in the protoplanetary disc surrounding a young star. They accomplished this feat with a cross-disciplinary expert analysis, including key input from laboratory spectroscopists. The vital role of CH3+ in interstellar carbon chemistry has been predicted since the 1970s, but Webb’s unique capabilities have finally made observing it possible — in a region of space where planets capable of accommodating life could eventually form.
This image is NIRCam’s view of the Orion Bar region studied by the team of astronomers. Bathed in harsh ultraviolet light from the stars of the Trapezium Cluster, it is an area of intense activity, with star formation and active astrochemistry. This made it a perfect place to study the exact impact that ultraviolet radiation has on the molecular makeup of the discs of gas and dust that surround new stars. The radiation erodes the nebula’s gas and dust in a process known as photoevaporation; this creates the rich tapestry of cavities and filaments that fill the view. The radiation also ionises the molecules, causing them to emit light — not only does this create a beautiful vista, it also allows astronomers to study the molecules using the spectrum of their emitted light obtained with Webb’s MIRI and NIRSpec instruments.
The two very large, bright stars are two of the three stars in the θ² Orionis system — the Trapezium Cluster is also known as θ¹ Orionis. The brightest star here, θ² Orionis A, is surrounded by particularly bright and red puffs of dust, which are reflecting the star’s light towards Earth. Its great brightness — it is visible with the naked eye — is due to the fact that θ² Orionis A is itself a ternary system made of three closely bound bright stars.
There are more proplyds visible in this image than just d203-506 — the Orion Nebula is replete with such new stars. In the very top left, a tiny star is visible within a long, dusty cocoon. This globule has formed from the star’s protoplanetary disc, as the disc is broken down by the energetic radiation of the Trapezium Cluster. Around the globule, a round shockwave is strikingly visible moving through the gas of the Orion Nebula.
[Image description: A nebula made of many layers of cloudy, colourful material. The top-left side of the image is brightly lit, filled with wispy, thin material in pale shades of pink and blue. A thick bar of denser, cloudier material crosses diagonally at the bottom right. It begins as orange and grows darker and sparser down to the corner. Two very bright stars, with very long diffraction spikes, lie in this sparse area.]

A theme of "Bulb" and I decided to photograph the filament of a light bulb going up in flames after the glass had been broken and the switch was turned on.
This would cause the filament to burn out when exposed to oxygen and would briefly burst into flames and emit a bit of smoke.
This was captured with the camera set to continuous shooting mode and is a frame towards the end of the sequence. i liked this one as the filament was visible and still glowing.
I also used a flashgun to help illuminate the glass and smoke and was impressed it kept up with the camera at 1/32 of it's power.
A filament (which at one point had an eerie similarity to a snake) broke away from the sun and out into space (Nov. 1, 2014). The video covers just over three hours of activity. This kind of eruptive event is called a Hyder flare. These are filaments (elongated clouds of gases above the sun's surface) that erupt and cause a brightening at the sun's surface, although no active regions are in that area. It did thrust out a cloud of particles but not towards Earth. The images were taken in the 304 Angstrom wavelength of extreme UV light.
