This composite image shows one of the studied clusters, NGC 3293, which is 11 million years old and is located about 8,300 light-years from Earth in the constellation of Carina. The image contains X-rays from Chandra (purple) as well as infrared data from ESA’s Herschel Space Observatory (red), longer-wavelength infrared data from NASA’s retired Spitzer Space Telescope (blue and white), and optical data from the MPG/ESO 2.2-m telescope at ESO’s La Silla Observatory appearing as red, white and blue.

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.

$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.
