This Hubble Space Telescope image of Comet 252P/LINEAR was photographed at 20:56 GMT on April 4, when the comet was 8.6 million miles from Earth. The visit was one of the closest encounters between this comet and our planet. This image was originally black and white and recorded only overall brightness. These brightness values were translated into a range of bluish hues. Such color ‘maps’ can be useful in helping to distinguish subtly varying brightness in an image. Image credit: NASA / ESA / J.-Y.
