How big is our galaxy compared to others?

To get an idea how small (or big) our galaxy is, try to imagine this. Light travels at 186,000 miles per second, that's about seven times around the globe in one second. One light year is how far light travels at that speed, non stop for one year. Our galaxy, the Milky Way, is over 100,000 light years across. And it's tiny compared to IC 1011, the biggest galaxy so far discovered.
