Image Quiz

What is this a picture of?

A. Scanning electron microscope image of a cockroach dropping?
B. Fossilized owl pellet?
C. Image of underwater landslide debris following the recent earthquake in the Solomon Islands?
D. A loosely consolidated asteroid?

To find out, keep on reading…

The answer is D. This image is of the 500-meter long asteroid Itokawa, and was taken by the Japan Aerospace Exploration Agency’s probe Hayabusa in 2005. Rather than being a solid piece of rock like most asteroids, it is a loosely consolidated clump of boulders and dust, held together by the object’s weak gravity.

This image was yesterday’s Astronomy Picture of the Day.

Grace and Peace
