According to Phil Plait:
Quote:
The picture of NGC 4452 is a short exposure; just a combination of 12.5 minutes using a blue filter and 20 using an infrared one. This means the sky is filled with galaxies!
And each one is an island Universe, made of billions of stars along with massive gas and dust clouds, and each as spectacular and amazing as this one seen up close.
