ALT Boulder-size blocks of water ice are around the rim of an impact crater on Mars, as viewed by the High-Resolution Imaging Science Experiment (HiRISE camera) aboard NASA’s Mars Reconnaissance Orbiter. The crater was formed Dec. 24, 2021, by a meteoroid strike in the Amazonis Planitia region. The uneven surface appears reddish-brown with rolling hills. The blocks of water ice are white. In the center of the image is the dark, shadowed impact crater which is an irregular oval in shape. Credits: NASA/JPL-Caltech/University of Arizona

ALT An image from NASA’s James Webb Space Telescope shows a bright dot at the center of star-filled black space. The bright dot is actually two stars meeting, as their orbits bring them together every 8 years. The stellar pair are surrounded by 17 rings of gas and dust that appear orangish gray. The rings have a slight rectangular shape and are very clear and defined starting at about 1 o’clock on a clockface. The rings start to break up a bit to our view traveling clockwise around the image. As you arrive at the 12:40 position, only parts of about six rings can be seen as they disappear from view.
