![]() This allows researchers to see crucial wavelengths of light and observe additional stars. With Webb's NIRCam, the space telescope's primary imaging instrument, scientists can see in the near-infrared range from 0.6 to 5 microns. Webb's better abilities for detecting infrared light unveil new details about the galaxy.Ĭredit: ESA/Hubble & NASA. The Hubble Space Telescope has also observed the Cartwheel Galaxy, although its imaging technology couldn't see as well through the large amount of dust. As the ring continues to expand, it interacts with the surrounding gas, triggering additional star formation. The outer ring, which has expanded for about 440 million years, hosts star formation and supernovas. The bright core of the Cartwheel Galaxy contains a lot of extremely hot dust and the brightest areas are home to large clusters of young stars. These features are why astronomers call the Cartwheel Galaxy and other galaxies like it 'ring' galaxies. The pair of rings expand outwards from the center of the collision. You can see two rings, a bright inner ring, and a surrounding ring. The high-speed collision affected the galaxy's shape and structure. The Webb team writes, 'Collisions of galactic proportions cause a cascade of different, smaller events between the galaxies involved the Cartwheel is no exception.'Ĭredit: NASA, ESA, CSA, and STScI. ![]() ![]() The Cartwheel Galaxy, seen largest in the image below, resulted from an intense high-speed collision between a large spiral galaxy and a smaller galaxy that's not visible. The Cartwheel Galaxy, also known as ESO 350-40 or PGC 2248, is a rare ring galaxy located about 500 million light-years away in the Sculptor constellation. It's a composite made using images from Webb's Near-Infrared Camera (NIRCam) and Mid-Infrared Instrument (MIRI). The image shows the Cartwheel Galaxy and its companion galaxies. NASA and the Webb Space Telescope team unveiled a new image from the James Webb Space Telescope this week, and unsurprisingly, it's amazing.
