Very interesting for sure but according to the rest of the article,
The observations show a bizarre X-pattern of filamentary structures near the
point-like nucleus of the object and trailing streamers of dust. This complex structure suggests the object is not a comet but instead the product of
a head-on collision between two asteroids traveling five times faster than a rifle bullet. Astronomers have long thought that the asteroid belt is
being ground down through collisions, but such a smashup has never before been seen.
So it seems to be a piece of debris that was hit just right?
From what I gather it's nothing to terribly special but I've been wrong before.
So there you have it, experts concluded already.
Edit: Thought I pasted it all.
