Meteor Misses Galaxy - Astronomy Picture of the Day - 2019 April 30



The galaxy was never in danger. For one thing, the Triangulum galaxy (M33),
pictured, is much bigger than the tiny grain of rock at the head of the meteor.
For another, the galaxy is much farther away -- in this instance 3 million light
years as opposed to only about 0.0003 light seconds. Even so, the meteor's path
took it angularly below the galaxy. Also the wind high in Earth's atmosphere blew
the meteor's glowing evaporative molecule train away from the galaxy, in angular projection.
