Abstract:
Beyond stars and the starstuff we are made of the sky is filled with hundreds of billion galaxies, all lit up by their stars. Stars account for less than one percent of the material in the Universe, and galaxies are held together by a new form of matter -- dark matter -- that accounts for 1/3 of the stuff in the Universe. The other 2/3 exists as in an even more mysterious form -- dark energy -- and is causing the expansion of the Universe to speed up, rather than slow down.
