The STEREO (Solar TErrestrial RElations Observatory) is a two-year mission conducted by NASA. It employs nearly identical twin telescopes one positioned ahead of Earths orbit and the other behind designed to study the Suns activities spectroscopically. However, it can sometimes pick up some very unusual findings! On December 26, 2011, the STEREO Behind Observatorys HI2 telescope captured an ambiguous triangle entering the field of view and moving from right to left just above the trapezoidal occulter as seen in the above movie. Just what is this thing?!
