Science : Long-term visitors to the moon will have to cope with daily temperatures that rise and fall up to 250 degrees Celsius. But that’s nothing compared to the day-night cycle on Upsilon Andromedae b, a giant extrasolar planet some 40 lightyears away. Going from the nightside to the dayside of this planet would be like jumping from an iceberg into a volcano, according to the first temperature variation measurements of a planet outside our solar system.
