Suppose you placed a camera at a fixed position, took a picture of the sky at the same time every day for an entire year, and overlaid all of the photos on top of each other. What would the sun look like in that combined image? A stationary dot? A circular path? Neither. Oddly enough, it makes a ‘figure 8’ pattern, known as the Sun’s analemma.
CERN and the University of California-Santa Barbara are collaborating in the search for the elusive substance that physicists and astronomers believe holds the universe together -- dark matter. Where is this search now in the realm of particle physics and what comes next?

1969-1970, takes Americans to the moon and back. Dreams of space dramatically intersect with dreams of democracy on American soil, raising questions of national priorities and national identity. The final episode also considers what happens to scientific and engineering programs — and to a country — after ambitious national goals have been achieved.
The simple act of making an apple pie is extrapolated into the atoms and subatomic particles (electrons, protons, and neutrons) necessary. Many of the ingredients necessary are formed of chemical elements formed in the life and deaths of stars (such as our own Sun), resulting in massive red giants and supernovae or collapsing into white dwarfs, neutron stars, pulsars, and even black holes. These produce all sorts of phenomena, such as radioactivity, cosmic rays, and even the curving of spacetime by gravity. Cosmos Update mentions the supernova SN 1987A and neutrino astronomy.
