A modest tongue-twister of my own. Inspired by this awe-inspiring image from APOD. Read the description. For all the figures you memorize in your general knowledge or science class, its images like this that give you some sense of the immensity of all things astronomical. The Spacestation is JUST about 200 km away from us, its even closer than you neighboring city, most likely. and the Sun is about a million times further away.. and YET, look at the size of it!!
Update: Just noticed that the image link actually linked to the APOD homepage which obviously changed after that day. The link is now updated and points to the correct image.
