Doesn't seem like much, eh? Until you realize that what you're looking at is an actual image of the surface of a star! This is the first time ever that astronomers have taken a photo of a star's surface. Holy magnificent magnification, Batman! They used a process called optical interferometry; read the science article .pdf if you want to know how they did it.

Wow!

Best,
Chris
