![]() The jet travels at nearly the speed of light and shows complex, twisted patterns near its source. Using a network of radio telescopes on Earth and in space, astronomers have captured the most detailed view ever of a jet of plasma from a supermassive black hole. The color bars refer only to information displayed in a. White ellipses at the bottom-left corners of b and c indicate the 20 × 20 μas 2 and 150 × 360 μas 2 convolving beams, respectively. c, The 7 mm VLBA-BU-BLAZAR program image obtained on 25 February 2014. Both images were aligned with respect to the pixel with maximum brightness. These start at 90% of the peak brightness and decrease by successive factors of 3/2 until they reach 5%. Contours correspond to our RadioAstron image, and are shown to compare the different scales probed. b, The 1:1 scale 1.3 mm EHT image obtained in April 2017. ![]() Their length and color are proportional to the level of linearly polarized intensity and fractional polarization, respectively. ![]() While both images in a show brightness temperature (color scale), the image on the right also shows the recovered electric vector position angles overlaid as ticks. a, Total intensity (left) and linearly polarized (right) RadioAstron image at 1.3 cm obtained on 10 March 2014. The filamentary structure of the jet in 3C 279 revealed by RadioAstron. ![]()
