The Supernova the Western World Didn't See
Almost 1000 years ago, Chinese astronomers observed a new star visible in the daytime sky, which they called a “guest star.” This supernova created what we now observe telescopically as the Crab Nebula. It is interesting that nowhere in Western Europe was this transient object recorded. Church dogma at the time declared the heavens to be eternal and unchanging, and it was much easier not to take notice than to be burned at the stake. Almost 500 years later, European astronomers had broken fre...But was recorded in China. An explanation for why it wasn't seen in Europe is that observers would probably be burned at the stake.

Discovery of the First Pulsar
In 1967, British scientists found a much nearer intense radio source turning on and off with astonishing precision, its period constant to ten or more significant figures. What was it? Their first thought was that it was a message intended for us, or maybe an interstellar navigation and timing beacon for spacecraft that ply the space between the stars. They even gave it, among themselves at Cambridge University, the wry designation LGM-1 - LGM standing for Little Green Men. However, they wer...Designated LGM-1 for "Little Green Men" because it gave off a repeating radio signal.
