Montage of Webb images showing six example barred galaxies, two of which represent the highest lookback times quantitatively identified and characterized to date. The labels in the top left of each figure show the lookback time of each galaxy, ranging from 8.4 to 11 billion years ago (Gyr), when the Universe was a mere 40% to 20% of its present age.

Webb Finds Six Barred Galaxies in Early Universe

These Hubble images show two massive galaxy clusters: MOO J1014+0038 (left) and SPT-CL J2106-5844 (right). The artificially added blue color is translated from Hubble data that captured a phenomenon called intracluster light. This extremely faint glow traces a smooth distribution of light from wandering stars scattered across the cluster. Billions of years ago the stars were shed from their parent galaxies and now drift through intergalactic space.

This Hubble image shows the globular cluster NGC 1850, which is located in the Large Magellanic Cloud, over 160,000 light-years from Earth. For this image, five filters were used with the camera to gather data. Two of the filters were at near-ultraviolet wavelengths, two more at visible light wavelengths, and the final one was in the near-infrared. The data gathered through the two ultraviolet filters is violet and blue. The data from the two visible light filters is green and orange. The color red denotes near-infrared data. The image follows chromatic order, which means the shortest wavelength in the image is blue while the longest wavelength is red. Chromatic order allows us to visualize wavelengths of light beyond our eye’s sensitivity in a way that is familiar to us. Image credit: NASA / ESA / N.

This Hubble image shows ESO 415-19, a spiral galaxy located some 450 million light-years away in the southern constellation of Fornax. In the top-right there is a smaller, orange elliptical galaxy. The color image was made from separate exposures taken in the visible and infrared regions of the spectrum with Hubble’s Advanced Camera for Surveys (ACS) and the Dark Energy Camera (DECam) on the Víctor M. Blanco 4-m telescope at Cerro Tololo Inter-American Observatory. Four filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / J.
