One of the hardest things for people to understand about the universe is just
how big it is. There are three approaches typically used in describing its size. The first, the song, was pioneered by
Monty Python (NSFWish, wireframe of naked woman) and then done just as masterfully by
the Animaniacs. The second, the zoom method has been featured
twice before here on the blue. The third method is the
comparison method (skip to 1:30, unless you like looking at a image of the solar system with terrible distorted orbits), yielding some truly
beautiful videos (this one found via the fantastic
Bad Astronomy blog). These videos go, at most, as far as looking at the local cluster or the Virgo Supercluster. There are two videos that attempt to show the size of the entire universe,
one unsuccessfully (although with great music) and
one successfully. (Warning, all links except the first one, are to YT videos).

An Interactive Space Simulator "Smash planets together, introduce rogue stars, and build new worlds from spinning discs of debris. Fire a moon into a planet or destroy everything you've created with a super massive black hole. You can simulate and interact with our solar system: the 8 planets,160+ moons, and hundereds of asteroids, the nearest 1000 stars to our Sun, and our local group of galaxies."

BAM! The
Microwave Anisotropy Probe's long-awaited
map of the
afterglow of the big bang was released today, and all of a sudden, most of the uncertainty in the concordance model of cosmology has disappeared. We now know, to within 1%, that the universe is 13.7 billion years old. We now know that Hubble constant is 71, plus or minus 4. And though the results agreed stunningly well with the
weird picture that cosmologists have about the nature of the cosmos, there was one surprise -- the first stars were born way before expected. Great day for science, and a likely future Nobel.

So you think the expansion of the universe is accelerating?
Think again! (Contains links to full paper in .pdf etc.)
