James Webb Space Telescope depicts Cartwheel Galaxy in stunning detail – By K. Holt (Engadget) / Aug 2, 2022
NASA says the observatory has shed more light on star formation within the galaxy.
NASA and its partners on the James Webb Space Telescope have shared more spectacular images from the observatory. This time around, they provided a fresh look at the Cartwheel Galaxy, which Hubble and other telescopes previously observed. NASA said JWST has been able to reveal new details about both star formation and the black hole at the center of the galaxy, which is around 500 million light years from Earth.
Using infrared light detection, JWST was able to peer through the dust that obscured the Cartwheel Galaxy from view when other telescopes observed it. The above image is a composite from JWST’s Near-Infrared Camera (NIRCam) and Mid-Infrared Instrument (MIRI). The JWST website has higher-resolution versions.
Data from NIRCam, which is the JWST’s primary imager, is colored in blue, orange, and yellow, while MIRI’s data is in red. NASA says the blue dots that appear in the red swirls of dust are individual stars or pockets of star formation. “NIRCam also reveals the difference between the smooth distribution or shape of the older star populations and dense dust in the core compared to the clumpy shapes associated with the younger star populations outside of it,” the agency noted.
