GIANT MARINE CROCODILE UNVEILED
发现大型海鳄
In January, scientists stunned the world with news that the largest marine crocodile ever found had been unearthed in an African desert. Based on a fossil skull and other bones discovered in Tunisia, it seems the fantastic beast could grow to be more than 30 feet long and weighed around three tons. Dubbed Machimosaurus rex, the 120-million-year-old animal offers crucial clues to a possible mass extinction event at the end of the Jurassic period, about 145 million years ago.
1月份,科学家发布了一个震惊世界的消息,迄今发现的最大海鳄在非洲沙漠中重见天日。根据在突尼斯发现的头骨化石和其他骨骼,科学家推测这种神奇的野兽能长到30多英尺,体重可达3吨左右。这种动物被称为君王马奇莫鳄,拥有1亿2千万年历史,为约1亿4500万年前侏罗纪末期动物大规模灭绝提供了重要线索。
NASA SPACECRAFT ARRIVES AT JUPITER

It only took five years and 1.7 billion miles, but in July NASA’s Juno spacecraft completed a daredevil maneuver to get into orbit around the largest planet in our solar system. Launched in August 2011, Juno is the first human-made object to orbit Jupiter since the end of the Galileo mission in 2003. The solar-powered spacecraft is designed to study the giant planet’s structure and intense magnetic field.
