Hi there!

Galaxies are groups of spinning matter pulled together by gravity. They contain trillions of planets, stars, and dust.

The Milky Way, our own galaxy, is home to more than a hundred billion stars and even more planets. It curves in a spiral, and is where we live.

The "Hubble Sequence" was created by Edwin Hubble.

There are elliptical, spiral, and irregular galaxies.

1. They found that the galaxies were actually moving apart at surprisingly fast speeds - even faster than light. Not much is known about this.

Hope this helps!
