Animations

Scale of Universe

What does the universe look like on small scales? On large scales? Humanity is discovering that the universe is a very different place on every proportion that has been explored. For example, so far as we know, every tiny proton is exactly the same, but every huge galaxy is different.
This interactive flash animation is a new window to many of the known scales of our universe. By moving the scroll bar across the bottom, you can explore a diversity of sizes. A new version is also available on which you can click to bring up descriptive information.


CMB analyser

Using the faint temperature patterns formed in the sky by cosmic microwaves, we can measure the age, shape, and composition of the early Universe. Looking out at the Universe, back in time, we see evolution of matter from hot plasma, to very simple clouds of hydrogen gas, to complex galaxies and planets.
Try changing yourself amounts of each ingredient and property. See if you can get the blue line (which represents your Universe) to match the red line (which is based on the measurements from the WMAP mission).
