“The Tail of a Christmas Comet” is copyrighted by The tail of a comet. NASA has permission to show it and we don't, so it isn't on this card.
See it on NASA's siteComet Leonard's tail streams across this three-degree-wide field of view, captured from Namibia. Just days after an outburst, the comet reached naked-eye visibility. Binoculars make it easier to spot near the western horizon after sunset. The image shows the comet's coma with a greenish tinge and the interaction of its ion tail with the solar wind.
