This image from the Solar Heliospheric Observatory (SOHO) taken the morning of Dec. 16, 2011 shows the comet head emerging from the right side of the sun. The comet does seem to have left its tail behind, however –that’s the nearly vertical streak that remains on the left side of the sun. The comet’s survival surprised NASA scientists.
