Twin eruptions threaten chaos for Ecuador

THE SMALL and economically racked Latin American nation of Ecuador may be hit by two simultaneous volcanic eruptions. A red alert had already been declared around one, Tungurahua, and 20,000 people evacuated from their homes when another, known as Guagua ("Baby") Pichincha, began threatening the capital, Quito, home to 1.2 million people.

SHOOTING STARS are one of the most spectacular sights in astronomy and, like most celestial events, they attract their own brand of superstition. When the Leonid meteors come crashing through our skies tonight they should, if the clouds part, produce more than a dozen streaks a minute.

It is a spectacular array of images, dismissing the myth that grey is necessarily dull.

Search engines: Serendipity - Life on Mars

THE UNLUCKIEST dog in history died on 28 June, 1911 in the town of Nakhla, Egypt. According to onlookers, it was struck by a rock from outer space, part of a meteor shower that peppered the region. Despite the dog's death, the Nakhla meteorite was a cause for celebration, because it was to play a major role in the story of extra-terrestrial science.
