Solar flares were first observed by Richard Carrington and Richard Hodgson independently on 1 September 1859 by projecting the image of the solar disk produced by an optical telescope through a broad-band filter. [50] [51] It was an extraordinarily intense white light flare, a flare emitting a high amount of light in the visual spectrum. [50]
A flare star is a variable star that can undergo unpredictable dramatic increases in brightness for a few minutes. It is believed that the flares on flare stars are analogous to solar flares in that they are due to the magnetic energy stored in the stars ' atmospheres. The brightness increase is across the spectrum, from X-rays to radio waves.
Satellite flare. Top: a simulated animation of a typical Iridium flare. Bottom: Both images show a flare of an Iridium satellite. Comet Holmes can be seen in the right image, slightly above the tree branch. Satellite flare, also known as satellite glint, is a satellite pass visible to the naked eye as a brief, bright "flare".
Sodium compounds glow yellow in a flame. A pyrotechnic colorant is a chemical compound which causes a flame to burn with a particular color. These are used to create the colors in pyrotechnic compositions like fireworks and colored fires. The color-producing species are usually created from other chemicals during the reaction.
Lens flare on Borobudur stairs to enhance the sense of ascending. A lens flare is often deliberately used to invoke a sense of drama. A lens flare is also useful when added to an artificial or modified image composition because it adds a sense of realism, implying that the image is an un-edited original photograph of a "real life" scene.
G’yu-mtsho, ZYPY: Yamzhog Yumco; Chinese: 羊卓雍錯; pinyin: Yángzhuó Yōngcuò, Yángzhuō Yōngcuò) is a freshwater lake in Tibet. It is one of the three largest lakes in Tibet. It is over 72 km (45 mi) long. The lake is surrounded by many snow-capped mountains and is fed by numerous small streams.
Post-eruptive loops in the wake of a solar flare, image taken by the TRACE satellite (photo by NASA). In solar physics, a solar particle event (SPE), also known as a solar energetic particle event or solar radiation storm, [a] [1] is a solar phenomenon which occurs when particles emitted by the Sun, mostly protons, become accelerated either in the Sun's atmosphere during a solar flare or in ...
Superflares are very strong explosions observed on stars with energies up to ten thousand times that of typical solar flares. The stars in this class satisfy conditions which should make them solar analogues, and would be expected to be stable over very long time scales. The original nine candidates were detected by a variety of methods.
