Answer to Blue Sky Trivia

Q. What country has the world’s bluest sky?

A. Anya Hohnbaum, a TV researcher who won a competition to travel in search of the world’s “bluest” sky found that Brazil is it. In 2006, she visited 20 different destinations on a 72-day trip organized by Expedia. To ensure that her findings were as scientific as possible, Hohnbaum used a special portable spectrometer adapted for her by scientists at the UK’s National Physical Laboratory (NPL).
