Scientists Get Serious about Extraterrestrials
The first woman to deliver one of Britain's most prestigious scientific lectures believes that we are not alone in the universe.
Dr Monica Grady's talk at the Natural History Museum, London, last night was devoted to the possible existence of extraterrestrial life.
