English: During its one-year mission, NASA's Wide-field Infrared Survey Explorer, or WISE, mapped the entire sky in Infrared light. Among the multitudes of astronomical bodies that have been discovered by the first NEOWISE portion of the WISE mission are 20 comets. This collage shows those 20 new comets together in a kind of family portrait.

The designations of the comets in the collage, from left to right, top to bottom are: 237P/LINEAR (2002 LN13), 233P/La Sagra (2009 WJ50), P/2009 WX51 (Catalina), P/2010 B2 (WISE), P/2010 D1 (WISE), P/2010 D2 (WISE), C/2010 D3 (WISE), C/2010 D4 (WISE), C/2010 DG56 (WISE), C/2010 E3 (WISE), C/2010 FB87 (WISE-Garradd), C/2010 G3 (WISE), C/2010 J4 (WISE), P/2010 K2 (WISE), C/2010 KW7 (WISE), 245P/WISE (2010 L1), C/2010 L4 (WISE), C/2010 L5 (WISE), P/2010 N1 (WISE), and P/2010 P4 (WISE).

The fuzzy background in each picture is due to random fluctuations in infrared light, primarily from Dust in our own solar system. Stars cannot be seen because they were subtracted during the process of combining multiple WISE pictures to make this view centered on the moving comets.
