Filaments and Plage Filaments are dark, thread-like features seen in the red light of hydrogen (H-alpha). These are dense, somewhat cooler, clouds of material that are suspended above the solar surface by loops of magnetic field.

Filament. A mass of gas suspended over the photosphere by magnetic fields and seen as dark lines threaded over the solar disk. A filament on the limb of the Sun seen in emission against the dark sky is called a prominence.

The filaments surrounding the edges of the nebula are what is left of the original outer layers of the star. The red color comes from emission of hydrogen.

Gas filaments and discs form stars and brown dwarfs. Some of the remaining gas falls in around these protostars forming protoplanetary discs and building up the masses of the protostars.

Such filaments act to pinch matter together in turn leads (for large enough filaments) to gravitational instabilities that cause clumps to form along the filaments like beads on a string.

Plasma filament that extends from the solar corona. A prominence is made up of relatively cold, dense plasma supported by the local magnetic field from falling back into the sun. They can survive like this for 200 days.

A solar filament collapsed on the Sun causing a CME to be released which struck on the 17th. A 12 hour geomagnetic storm took place and aurorae was seen. Click here for an animation of the CME. Click here for an image of the aurora.

Whatever system of sampling is used, the outcome is plots revealing filamentary or sponge-like structures, reminiscent of aqueous media even though the data are in the form of discrete points. gives an indication of neighboring superclusters.

The filament of a lightbulb has some large brightness (it has a very small surface area). When you look at the filament, its image is focused onto your retina in your eye and that image contains the full painful brightness of the filament.

Sources that depend on thermal emission from a solid filament, such as incandescent light bulbs, tend to have low overall efficacy compared to an ideal blackbody source because, as explained by Donald L.

The incandescent electric light has as its light source the heat that results from the ohmic resistance of the filament to the electric current. A red-hot poker absorbs heat directly from the fire resulting from the liberation of chemical energy.

Arches Cluster (inset) at X-ray wavelengths, with radio filaments A cluster of about 150 hot, young stars concentrated within a radius of about one light-year, making it the most compact cluster of stars in our Galaxy.

Huge dark matter clumps the size of superclusters gather together under the action of gravity into a network of filaments. Where the dark matter filaments intersect, regular matter concentrates into galaxies and galaxy clusters.

Whereas clusters are typically found in the filaments and walls of the universe's "soap bubble," superclusters are at the intersections of the walls.

It can be found: northeast of Delta and Gamma Sagittae, and southeast of Albireo (Beta1 Cygni); east of the Dumbbell Nebula; southwest of the Veil or Witch's Broom, Lace-work, Cirrus, Network, and Filamentary nebulae, ...

A solar prominence (also known as a filament) is an arc of gas that erupts from the surface of the Sun. Prominences can loop hundreds of thousands of miles into space.

These views, from a mosaic of ground- based (from the National Optical Astronomy Observatories) and Hubble images, show that the apparently smooth ring is actually made of myriad dense "comet-like" filaments that point away from the central star.

A hot solid, liquid or dense gas will produce a continuous spectrum (blackbody or thermal spectrum) Here, it is a hot lightbulb filament.

Such motions, and the pronounced wrapped filamentary structure seen in nearby jets such as M87 and Centaurus A, suggest an important role for motion in helical patterns.

Instead, superclusters of tens of thousands of galaxies are arranged in long, stringy, lacelike filaments, arranged around large voids.

You should see a continuous form of the spectrum because the light from a flashlight and most other light sources is from a heated solid filament.

Like soap bubbles in a sink, they form into dense filaments with voids between. Our best model for how the universe began, the Big Bang, gives us a picture of a universe filled with a hot, uniform soup of fundamental particles.

These bands Julius calls dispersion bands, and then, assuming that a species of tubular structure prevails within a large part of the sun (such as the filaments of the corona suggest for that region), he applies the weakening of the light to explain, ...

This theory is a version of Jeans's theory in which the Sun interacts with a nearby protostar dragging a filament of material from the protostar.

In a rarefied hot gas, emitted light no longer follows a simple pattern dictated by the temperature, like red-hot iron or a lightbulb filament (both of which are solid matter).

The Veil Nebula West (NGC 6960) and The Veil Nebula East (NGC 6992/95) are fine filaments seemingly suspended in the cosmos. It takes quite a large scope, perfect conditions, and plenty of patience to appreciate their delicate lines.

OPT CAL Optical Calibration Type of calibration in which the NIMS dispersion grating is calibrated by pointing it at a known (incandescent tungsten filament) light source.

Stable filaments often become unstable and erupt, but they may also just fade away. The prominences never fall downward; they always erupt upward, because all unattached magnetic fields have a tremendous buoyancy and attempt to leave the Sun.

These tend to be shaped as flattened disks, sheets, or filaments. These superclusters then form surfaces like the surfaces of bubbles, with virtual voids in between. These may be the largest structures in the universe.

The Hubble Space Telescope's high resolution has allowed astronomers to see dense star clusters, dust lanes with tiny regions of dense gas, and filaments of glowing gas in the core of a starburst galaxy.

The Largest structures discovered in the Universe are systems of voids and clusters. At this scale the Universe takes on a foamy look. The voids appear as great bubbles and galaxies lie along them in great filaments that connect Superclusters.

The nebula is almost spherical with some bright filaments. EAGLE NEBULA The Eagle Nebula (M16) consists of enormous columns of cool interstellar hydrogen gas and dust that are about 7,000 light-years from Earth (in the constellation Serpens).

The Vela supernova remnant, a large wispy filamentous nebula is all that remains of a star that blew itself into rather spectacular pieces about 12,000 years ago. It is as wide as ten full moons.

Temperature also controls the type and quantity of thermal radiation emitted from a surface. One application of this effect is the incandescent light bulb, in which a tungsten filament is electrically heated to a temperature at which significant ...
