Hubble scopre un misterioso oggetto nello spazio

P/2010 A2. Viaggia a 18,000 km/h e ha una strana forma a X. Potrebbe essere il risultato di uno scontro tra due asteroidi.
"If this interpretation is correct, two small and previously unknown asteroids recently collided, creating a shower of debris that is being swept back into a tail from the collision site by the pressure of sunlight. The filamentary appearance of P/2010 A2 is different from anything seen in Hubble images of normal comets, consistent with the action of a different process."
In parole povere, la NASA non ha la piu' pallida idea di cosa si tratta...
