Image of the Day: Pulsar –“First Thought to be Signals from an ET Form of Life”

Pulsar3

Pulsars are among the most exotic objects found in the galaxy. They are the peculiar relics of massive stars that have ended their lives in a tremendously powerful explosion called "supernova".

The first pulsar was discovered by a woman from Northern Ireland, Dame Jocelyn Bell-Burnell during her PhD, in 1967. As at the discovery time people had no idea what these radio signals were, the found objects were dubbed little green men (LGM) as one possibility could have been that the sounds came from some extraterrestrial form of life.

This link takes you to an article originally presented as an after-dinner speech by Jocelyn – it's a very personal and entertaining account of the discovery: "Little Green Men, White Dwarfs or Pulsars?"
