|Five planets line up 'like string of pearls'
Five planets in our solar system have lined up in a celestial event called a conjunction. All across the world, Mercury, Venus, Mars, Jupiter and Saturn could be seen without a telescope. The rare planetary conjunction was visible in clear skies before dawn. A weather website said the best time to view it was about an hour before sunrise. An astronomer said it was, "like a string of pearls spread out from close to the horizon". She was particularly happy at seeing Mercury, which is usually hard to see. She said: "It is very satisfying [to] see this faint twinkling planet."
