Sponge Moon

Today’s Astronomy Picture of the Day is of Hyperion, one of Saturn’s 34+ moons.

Here is the APOD discription of this image:

Explanation: What lies at the bottom of Hyperion’s strange craters? Nobody knows. To help find out, the robot Cassini spacecraft now orbiting Saturn swooped past the sponge-textured moon in late 2005 and took an image of unprecedented detail. That image, shown above in false color, shows a remarkable world strewn with strange craters and a generally odd surface. The slight differences in color likely show differences in surface composition. At the bottom of most craters lies some type of unknown dark material. Inspection of the image shows bright features indicating that the dark material might be only tens of meters thick in some places. Hyperion is about 250 kilometers across, rotates chaotically, and has a density so low that it might house a vast system of caverns inside.

The past 30 years of solar system exploration have revealed an astounding variety and complexity of the planets, moons, and other objects in our solar system. Whether one is studying astronomy, chemistry, or cell biology, I’ve learned that we should expect:

  • Order
  • Complexity
  • Surprises

Our discoveries in the natural world reflect a Creator who is a lawmaker (the universe is orderly and there are fundamental laws which underlie its workings), complex (how can we ever understand the relationships within the Trinity), and full of surprises.

May you find joy in all the things God has created, and most supremely, in his son, Jesus Christ.

Grace and Peace
