Webb telescope reveals colourful cosmic cartwheel
The Independent
The James Webb Space Telescope has revealed new details in yet another old Hubble Space Telescope Image, this time returning a sparkling pink and blue image of the distant Cartwheel galaxy, located about 500 million lights years away. The Cartwheel galaxy was a spiral galaxy like out own Milky Way until a collision with a smaller galaxy began around 440 million years ago. The collision altered the galaxy so that it looks more wheel like, with a bright central ring of young star clusters, and an outer ring dominated by star formation and stars dying in supernovae. The new Webb image highlights the way Webb’s different instruments can combine to offer scientists new views on the cosmos. The image is a combination of data from Webb’s Near-Infrared Camera, or NIRCam, and the Mid-Infrared Instrument, or MIRI. NIRCAM is is better able to peer through dust and gas to witness young stars and star formation in the distant galaxy, and the NIRCAM contributions to the image show up as blue, orange and yellow. MIRI, meanwhile, picks up the detailed structure of the dust and gas that NIRCam peers through, revealing silica dust and hydrocarbons that show up as red in the image. This dusty material creates massive “spoke”-like structures to the wheel, and can also be seen a 2018 Hubble image of the galaxy. But the new details revealed by Web will help scientists better understand the past and future evolution of the galaxy as it continues to reel from the collision, according to a Nasa blog.
