Hubble just discovered a mysterious X-shaped object travelling at 11,000mph. But according to the National Aeronautics and Space Administration (NASA), the labeled P/2010-A2 “may” just be a comet or a product of a collision of two asteroids.

However, David Jewitt, an investigator from the University of California in Los Angeles, disputed this and said that the texture of the object is far different from the “smooth dust envelopes of normal comets.”

He further said that, “The filaments are made of dust and gravel, presumably recently thrown out of the nucleus. Some are swept back by radiation pressure from sunlight to create straight dust streaks. Embedded in the filaments are co-moving blobs of dust that likely originated from tiny unseen parent bodies.”

But according to some space enthusiasts, the most curious thing about the P/2010-A2 is that its 46-foot-wide nucleus lies outside the dust halo and is separated from the trail. It is said to have been never seen in a comet or any other object in the solar system.

The images are taken by the Hubble between January 25 and 29. NASA scientists and other experts are still going through an argument as to what really the object is made of.
