Oct 7 Recap

Today's host was Dr. Chris Ryan.

1. Nobel Prize in Physics
Half of the Nobel Prize in Physics is rewarded to Willard Boyle and George Smith for their development of the charge-coupled device (CCD). We all know how important CCD is to astronomy. Read the nature news here.

An interesting article in The Globe and Mail speculated about who would win the Nobel Prize if the Prize is to be rewarded to the discovery of "exoplanets". The article uncovered the melodrama story of two Canadian astronomers, Gordon Walker and Bruce Campbell, who were the pioneers of the world's most successful search technique for exoplanets.
