Scientists Find Planet with Metal Clouds that Rain Gems

Ok, let's go to outer space! We're going to a super weird planet that scientists found in 2015. But… it is really, really far away from earth. Humans will never be able to go there. Even if we traveled at the speed of light, it would take more than 800 years to get there! 科學家發現一顆很遠的行星，就算我們用光速，也要800年才能到！ Scientists found the planet with a special telescope. The planet is called WASP-121b. 他們用天文望遠鏡找到這顆星球，名字叫做WASP-121b。 But… everything on this planet is weird! It's bigger and hotter than Jupiter… and scientists say it has clouds made out of metal… Metal clouds! 這顆星球比木星更大、也更熱，而且它的雲含有金屬！ And, when it rains on this huge, hot planet… the rain is probably made out of gems… like rubies and other precious stones! 下雨的時候，掉下來的可能是紅寶石之類的珍貴石頭！ Planet WASP-121b is like our moon in one way… it is "locked" to its sun. That means that one side always faces its sun and one side always faces space… So, one side is very hot… but the other side is not. 這顆行星跟我們的月球一樣，有半邊會永遠面對太陽，所以非常熱；另一半完全不會。 What an amazing universe! It's wonderful to discover new planets… like this one… with metal clouds that rain gems! ________________________________ Vocabulary 這顆距離我們八百多光年的行星，真是有夠奇怪！ 1.
