NASA has released a stunning photo of Comet ISON against a background of stars and distant galaxies. The composite image was stitched together from five photos snapped by the space agency’s Hubble Space Telescope on April 30, 2013.
According to scientists, the five photos were captured by Hubble’s Wide Field Camera 2 UVIS instrument. Three exposures were taken with a filter that transmits yellow and green light (seen as blue in the image) and two used a filter that let in red and some infra-red light.
