The object itself was detected in ESO images dating back to 1980, but its identification as a quasar occurred only several decades later. [2]An automated analysis of 2022 data from the European Space Agency's Gaia satellite did not confirm J0529-4351 as too bright to be a quasar, and suggested it was a 16th magnitude star with a 99.98% probability.
Quasar is an American brand of electronics, first used by Motorola in 1967 for a model line of transistorized color televisions. These TVs were marketed as containing all serviceable parts in a drawer beside the picture tube. It was then established as a subsidiary brand, with all Motorola-manufactured televisions being sold as Quasar by Motorola.
The idea that the emission was caused by a civilization was rejected when the radio source was later identified as one of the many varieties of a quasar. [ 3 ] The American folk rock band The Byrds whimsically reflected the original view that CTA-102 was a sign of extraterrestrial intelligence in their song "C.T.A.-102" from their 1967 album ...
High brightness sunlight readable monitors are typically used commercially in kiosks, vending systems, pipeline inspection systems, outdoor digital signage and advertising, in sports stadiums, in military vehicles, on ships for navigation systems, on bus and train platforms, and much more.
3C 273 is a quasar located at the center of a giant elliptical galaxy in the constellation of Virgo. It was the first quasar ever to be identified and is the visually brightest quasar in the sky as seen from Earth, with an apparent visual magnitude of 12.9. [2] The derived distance to this object is 749 megaparsecs (2.4 billion light-years).
The level of a video signal usually corresponds to the brightness, or luminance, of the part of the image being drawn onto a regular video screen at the same point in time. A waveform monitor can be used to display the overall brightness of a television picture, or it can zoom in to show one or two individual lines of the video signal.
APM 08279+5255 was initially identified as a quasar in 1998 during an Automatic Plate Measuring Facility (APM) survey to find carbon stars in the galactic halo.The combination of its high redshift (z=3.87) and brightness (particularly in the infrared) made it the most luminous object yet seen in the universe.
In practice, because the alignment needed is so precise and difficult to predict, microlensing is very rare. Events, therefore, are generally found with surveys, which photometrically monitor tens of millions of potential source stars, every few days for several years. Dense background fields suitable for such surveys are nearby galaxies, such ...
