Since 1950 many people have loved being flies on the walls in Ambridge to hear the drama and gossip of several families in The Archers that don’t actually exist. The genealogical roots of many celebrities have been investigated with a fine tooth comb over the years in…

Here’s an idea….

Multiple milestones in astronomy have reshaped our understanding of the universe: from Apollo 8’s Earthrise photo to Copernicus’ heliocentric model, Galileo’s observations, Hubble’s expanding universe, and Penrose’s cyclic cosmology theory….
