Description

Because of it is approaching another time to us, the comet Garradd has increased meaningfully your size and brightness, reaching 6.5 magnitude and becoming observable at naked eye from very dark sites. Photographically your image shows clearly your both tails, of whitish dust and bluish gas, completely opposite one direction contrary to other, because of our viewing angle.
