My next pick hails from a distant sonic galaxy, far removed from the sleek modern sound and high-octane playing of Ms. Argerich and company.

Each building a planet in configuration with the next, a galaxy of colors.

"I see a shiny asteroid in New York's current culinary galaxy.

Some aggregates of galaxies have enough mass to be bound together by gravitational forces, and these galaxy clusters can be considered as independent astrophysical objects in their own right.

A typical galaxy fills only about one-millionth of the volume of space that contains the galaxy, and the galaxies themselves are extremely tenuous.

If you were to fly a spaceship to a random point in the universe, the chances of landing within a galaxy are about one in a million at the present time.

If you were to drive a spaceship to a random point in our galaxy, the chances of landing within a star are extremely small, about one part in one billion trillion (one part in 1022).

Direct collisions between the stars in a galaxy are exceedingly rare.

Consequently, it takes a very long time, much longer than the current age of the universe, for stellar collisions and other encounters to affect the structure of a galaxy.

We now know with certainty that planets are relatively commonplace in the galaxy, and not just the outcome of some rare or special event which occurred in our solar system.

How about the number of stars in the sky?The number of stars in our galaxy is close to one hundred billion, again a relatively small number.

Some stellar remnants are ejected far beyond the edge of the galaxy, while others fall in towards the center.

On average, at any given time, a few such stars will be shining in a galaxy the size of our Milky Way.

Every so often, as two white dwarfs collide, the galaxy is rocked by a supernova explosion.

These white dwarfs sweep up dark matter particles, which orbit the galaxy in an enormous diffuse halo.
