Great Nebula in Carina
Also the Orion Nebula
The Pillars of Creation
Rotten Egg Nebula
All of these are bigger than THE WHOLE SOLAR SYSTEM! And i'm not talking about maybe double the size... The Pillars of Creation are 20,000 times larger that the solar system! WOW!! and that is not even the biggest of them all! The Tarantula Nebula is the largest of them, measuring 600 light years (6 x 10 to the power of 18 meters)! BLIMEY, I feel very small right now!
