Hubble has discovered a mysterious X-shaped object travelling at 17,700km/h. NASA says that P/2010-A2 may be a comet, product of the collision between two asteroids.The weirdest thing, however, is not only the prettyful X-shaped debris pattern, but the fact that its 140m-wide nucleus is outside the dust halo and separated from the trail. This behaviour is something which has never been seen before in a comet or any other solar-system-swooshing object. In other words: They have no clue about what this is, and they are still speculating about how this object was formed.

Stars and dust clouds towards the center of the Milky Way. Stars form half the detectable mass of the Milky Way. The other half is in the form of gas and dust.
The red glow originates from hydrogen gas predominantly behind the nebula, ionized by the nearby bright star Sigma Orionis. The darkness of the Horsehead is caused mostly by thick dust, although the lower part of the Horsehead’s neck casts a shadow to the left. Streams of gas leaving the nebula are funneled by a strong magnetic field. Bright spots in the Horsehead Nebula’s base are young stars just in the process of forming.
