In 2011 the Stereo-B Spacecraft captured a tetrahedral shaped anomaly which came from the same region in space as this new anomaly. NASA at the time stated that the tetrahedral shaped anomaly was an imaging artifact due to a reflection inside the spacecraft.
Now, this new 2016 anomaly is circular shaped, actually there are two circles at almost the same size next to each other and may be connected with each other makes it hard to believe that this object is another internal reflection.
According to Mrmb333 this object is heading towards earth, but personally I doubt if that is the case.
And on May 31, during a speech at the FEMA National Response Coordination Center in Washington, Obama said that every American is responsible for preparing for disasters, and that includes “having an evacuation plan” and “having a fully stocked disaster supply kit.”
I do not know whether all these warnings have something to do with the threat of a terror attack, a nuclear or a natural disaster or a threat from outer space, but whatever the object is and what it is doing is certainly questionable.
