Stars?


I took the picture above a few days ago. I thought it was very similar to an image I had seen at the Bad Astronomer of a globular star cluster (see below). Somewhat fewer stars, but definetly similar. However, the difference in scale is about 21 orders of magnitude. My image shows silver particles electrodeposited by a colleague on an ITO electrode. The width of the "cluster" is roughly 100 µm. It's a dark field microscope image which is why the particles appear as diamonds, or stars, on a dark background.
