For one thing, the Triangulum galaxy [4] (M33), pictured, is much bigger than the tiny grain of rock [5] at the head of the meteor. For another, the galaxy is much farther away -- in this instance 3 million light year [6] s as opposed to only about 0.0003 light seconds. Even so, the meteor's path [7] took it angularly below the galaxy. Also the wind high in Earth's atmosphere [8] blew the meteor's glowing evaporative molecule train [9] away from the galaxy, in angular projection [10] . Still, the astrophotographer was quite lucky to capture both a meteor and a galaxy [11] in a single exposure -- which was subsequently added to two other images of M33 to bring up the spiral galaxy [12] 's colors. At the end, the meteor [13] was gone in a second, but the galaxy [14] will last billions of years.
