CallUrl('astronomy>swin>edu>auucsd>edushtml',0), A ~TildeLink() is a portion of the chromosphere that rises higher than normal. ~TildeLink()s seen over the limb are also known as prominences. Filaments are solar prominences that are viewed against the solar surface rather than being silhouetted along the outer edges of the disk. filament - (n.) (a) A feature of the solar surface seen in Ha as a thin, dark wavy line. [H76] R MonocerotisAn A-F pec variable star that illuminates the variable cometary nebula NGC 2261. The galaxy wall subtype of filaments have a significantly greater major axis than minor axis in cross-section, along the lengthwise axis. The rapidly spinning neutron star embedded in the center of the nebula is the dynamo powering the nebula's eerie interior bluish glow.

CallUrl('www>astronomy>ohio-state>edu<~poggehtml',0), Commenting on its latest Horsehead Nebula images, Prof Matt Griffin explained: "You can see all the things we look for in Herschel images; the ~TildeLink()s, the bubbles; the wispy material, the reddish material that hasn't yet actually started to form stars. You can click on any letter of the alphabet below to jump directly to that section in the glossary listing. CallUrl('lifeng>lamost>orgHTM',0), CMEs are often but not always associated with erupting prominences, disappearing solar ~TildeLink()s, and flares. Any of the dark, sinuous lines visible through certain filters on the disk of the Sun. A filament is a prominence projected on the solar disk. 1.2 Astronomy A slender, elongated body of luminous gas or other material in the sun’s atmosphere, a nebula, or interstellar space. But, if you look at it through a prism or through those funky glasses that you can get that make everything into rainbows at carnivals, what you see is.

But there is so much more to know about these grand and glorious star islands in space! It is as wide as ten full moons. Our Milky Way exists in a small cluster, the Local Group, which also incorporates the Triangulum and Andromeda spiral galaxies as well as a handful of diminutive dwarf galaxies. What is the meaning of filament? The discovery supports the idea that dark matter drove the formation of galaxies and larger cosmic structures and resolves a discrepancy in previous studies about how much dark matter the universe contains. 1, 35–42. filament, in astronomy: see chromosphere chromosphere [Gr.,=color sphere], layer of rarefied, transparent gases in the solar atmosphere; it measures 6,000 mi (9,700 km) in thickness and lies between the photosphere (the sun's visible surface) and the corona (its outer atmosphere).
