ALT This image shows a collection of 25 new space images celebrating the Chandra X-ray Observatory’s 25th anniversary. The images are arranged in a grid, displayed as five images across in five separate rows. Starting from the upper left, and going across each row, the objects imaged are: Crab Nebula, Orion Nebula, The Eyes Galaxies, Cat’s Paw Nebula, Milky Way’s Galactic Center, M16, Bat Shadow, NGC 7469, Virgo Cluster, WR 124, G21.5-0.9, Centaurus A, Cassiopeia A, NGC 3532, NGC 6872, Hb 5, Abell 2125, NGC 3324, NGC 1365, MSH 15-52, Arp 220, Jupiter, NGC 1850, MACS J0035, SN 1987A.

The skeletal frame of VIPER is in the center of the image, with the NASA “meatball” insignia looming above on the wall behind it.

ALT Red dual opposing jets coming from young stars fill the darker top half of the image, while a glowing pale-yellow, cave-like structure is bottom center, tilted toward two o’clock, with a bright star at its center. The dust of the cave structure becomes wispy toward eight o’clock. Above the arched top of the dust cave three groupings of stars with diffraction spikes are arranged. A dark cloud sits at the top of the arch of the glowing dust cave, with one streamer curling down the right side. The dark shadow of the cloud appears pinched in the center, with light emerging in a triangle shape above and below the pinch, revealing the presence of a star inside the dark cloud. The largest jets of red material emanate from within this dark cloud, thick and displaying structure like the rough face of a cliff, glowing brighter at the edges.
