Quantum scrambling is one suggestion for how information can fall into a black hole and come out as random-looking radiation. Perhaps, the argument goes, it is not random at all, and black holes are just excellent scramblers. Image credit: E. Edwards / Joint Quantum Institute.

While the purpose of this image was to focus on the bright star at the center for alignment evaluation, Webb’s optics and NIRCam are so sensitive that the galaxies and stars seen in the background show up. At this stage of Webb’s mirror alignment, known as fine phasing, each of the primary mirror segments have been adjusted to produce one unified image of the same star using only the NIRCam instrument. This image of a star called 2MASS J17554042+6551277 uses a red filter to optimize visual contrast. Image credit: NASA / STScI.

This Hubble image shows NGC 1097, a barred spiral galaxy some 48 million light-years away in the constellation of Fornax. The color image is made up of observations from Hubble’s Wide Field Camera 3 and Advanced Camera for Surveys in the ultraviolet, near-infrared, and optical parts of the spectrum. Seven filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.
