This Hubble image shows the carbon star CW Leonis. The image incorporates observations from 2011 and 2016 by Hubble’s Wide Field Camera 3 (WFC3). The star is brightest in the red filters, R and I, and therefore the simmering orange color pervading the center of the image well represents the real color of the star.
