$This Webb image shows NGC 7469, a barred spiral galaxy some 206 million light-years away in the constellation of Pegasus. The galaxy has blue-purple hues with orange-red regions filled with stars. NGC 7469’s companion galaxy, IC 5283, is partly visible in the lower left portion of this image. Also visible is large diffraction spike, which appears as a star pattern over the central region of the galaxy. Lots of stars and galaxies fill the background scene.

This Hubble image shows NGC 5495, a spiral galaxy some 319 million light-years away in the constellation of Hydra. The color image was made from separate exposures taken in the visible and infrared regions of the spectrum with Hubble’s Wide Field Camera 3 (WFC3). Five filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.
