This Week's Letters

A group of astronomers and planetary scientists defend Pluto's designation as a planet, saying, "we believe that [Pluto] should be considered as the prototype of a third class of planet." Letter writers point out that omnidirectional mirrors have been manufactured for at least 30 years. And an atmospheric physicist warns that great care should be taken in using readings from weather satellites to reach conclusions about global warming and its effects.
