“This result is a significant challenge to our current understanding of quasar jets,” he added.“This is like looking through the hot, turbulent air above a candle flame,” said Michael Johnson, of the Harvard-Smithsonian Center for Astrophysics (CfA). This star is above and to the right of 3C273 in the above screen capture.
This image from Hubble’s Wide Field and Planetary Camera 2 (WFPC2) is likely the best of ancient and brilliant quasar 3C 273, which resides in a giant elliptical galaxy in the constellation of Virgo (The Virgin). For example, 3C 273 is the 273rd entry in the catalogue (ordered by right ascension). Researchers at the University of Cambridge have developed a new method for detecting and measuring one of the most powerful, and most mysterious, events in the universe — a black hole being kicked out of its host galaxy and into intergalactic space at speeds as high as 5,000 kilometres per second (11 million miles per hour). The … Its light has taken some 2.5 billion years to reach us. They pointed this system at a quasar called 3C 273, more than 2 billion light-years from Earth. The brightest quasar in the sky is 3C 273 in the constellation of Virgo. For the supermassive black hole at the center of our Milky Way galaxy, it’s been a long time between dinners. 3C 273 is in the center of this full FOV image at half scale. [ 24 July 2020 ] We present absolutely calibrated far-ultraviolet spectrophotometry of the quasar 3C 273 covering the 900-1800 Å range. Later, astronomers also discovered a star-like point of light at the same position in the sky. Using this interferometer, Caltech radio astronomer, Tom Matthews, obtained an accurate position for 3C 48 … That limit, scientists thought, was about 100 billion degrees. But within the next generation, it should become possible to detect signs of life on planets orbiting distant stars.
[ 30 July 2020 ] If life crossed the vast gulf of interstellar space long ago, how would we tell? For example, did that life arise spontaneously? “We had never been able to see such distortion of an extragalactic object before,” he added.“The amazing resolution we get from RadioAstron working with the ground-based telescopes gives us a powerful new tool to explore not only the extreme physics near the distant supermassive black holes, but also the diffuse material in our home Galaxy,” Johnson said.The RadioAstron satellite was combined with the Green Bank Telescope in West Virginia, The Very Large Array in New Mexico, the Effelsberg Telescope in Germany, and the Arecibo Observatory in Puerto Rico. Scientists ponder inconclusive data from dark matter experiment 21 June 2020. NASA’s Hubble Space Telescope has found that the black hole ate its last big meal about 6 million years ago, when it consumed a large clump of infalling gas. We show that at 18 cm, these estimates most likely arise from refractive substructure introduced by scattering in the interstellar medium. The above chart is the measured 3C273 spectrum with redsift emission line markers.
Our ~3 Å resolution spectra were obtained with the Hopkins Ultraviolet Telescope (HUT) during the Astro-1 mission in 1990 December and during the Astro-2 mission in 1995 March. NASA’s Perseverance rover leaves Earth bound for Mars It was the first quasar ever to be identified, and was discovered in the …
Signals received by the orbiting radio telescope were transmitted to an antenna in Green Bank where they were recorded and then sent over the internet to Russia where they were combined with the data received by the ground-based radio telescopes to form the high resolution image of 3C 273.In 1963, astronomer Maarten Schmidt of Caltech recognised that a visible-light spectrum of 3C 273 indicated its great distance, resolving what had been a mystery about quasars.

The most important adjustment when viewing astro images is to see the differences in all of the black bands.
