| Description |
These new versions of Webb’s first images combine its infrared data with X-rays collected by NASA’s Chandra X-ray Observatory, underscoring how the power of any of these telescopes is only enhanced when joined with others. Webb brilliantly shows how the galaxy cluster SMACS J0723, located about 4.2 billion light-years away, contains hundreds of individual galaxies. Galaxy clusters, however, contain far more than their galaxies alone. As some of the largest structures in the universe, they are filled with vast reservoirs of superheated gas that is seen only in X-ray light. In this image, the Chandra data (blue) reveals gas with temperatures of tens of millions of degrees, possessing a total mass of about 100 trillion times that of the Sun, several times higher than the mass of all the galaxies in the cluster. Invisible dark matter makes up an even larger fraction of the total mass in the cluster.

Mahler; IR: NASA/ESA/CSA/STScI Image description: An image of the galaxy cluster SMACS 0723 which contains hundreds of individual galaxies in a sea of black space. Here the galaxies resemble specks of golden orange and white light. Some gleam with diffraction spikes radiating from the center. Some look like tiny swirling pinwheels. Some of the galaxies located far behind the cluster resemble short arcing streaks, their light having been bent by the mass of galaxies in the cluster. Near the center of the image, where some of the brightest galaxies reside, is a faint, pale blue haze. This is superheated gas with a total mass of about 100 trillion times that of the sun, revealed by the Chandra observatory. |
