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.
StunRay is a less-lethal optical incapacitation effector developed by Genesis Illumination Inc. It uses collimated incoherent (non-laser) broad spectrum visible and near infrared light from a short-arc lamp to safely and temporarily impair vision, disorient and incapacitate aggressors for 5 seconds to 3 minutes without causing physical harm.
It displayed near-infrared flares in 2014 and 2017. [ 13 ] [ 14 ] By 2020, AO 0235+164 had brightened again, displaying an optical flare that reached its peak in 2021. However, when compared to previous flares, it is shown weaker despite emission at all wavelengths increasing from gamma rays to millimeter waves and its light curve exhibiting a ...
This optical illusion dividing the internet tricks our brains into seeing the color red in a traffic light even though it's actually gray. This optical illusion dividing the internet tricks our ...
In July and August 2007, 3C 454.3 flared to near-historic levels, only two years after its record-breaking 2005 optical flare. Luckily, Spitzer Space Telescope and Chandra X-ray Observatory were already scheduled for simultaneous observations. Swift, RXTE and the new gamma-ray AGILE spacecraft responded to this target of opportunity, and were ...
This footage from the ISS shows a red sprite over East Asia immediately before 0:07, directly above the large lightning flash towards the upper right of the frame. In order to film sprites from Earth, special conditions must be present: 150–500 km (93–311 mi) of clear view to a powerful thunderstorm with positive lightning between cloud and ...
A flare star with orbiting planet (artist's impression) Flare stars are intrinsically faint, but have been found to distances of 1,000 light years from Earth. [8] On April 23, 2014, NASA's Swift satellite detected the strongest, hottest, and longest-lasting sequence of stellar flares ever seen from a nearby red dwarf, DG Canum Venaticorum.
Those brilliant red spots, say experts, are called solar prominences. ... Was that a solar flare during the eclipse? The total solar eclipse seen above downtown Evansville, Ind., Monday, April 8 ...
