14-04-02 Evidence left at the crime scene is abundant and global: Fossil remains show that sometime around 252 million years ago, about 90 percent of all species on Earth were suddenly wiped out -- by far the largest of this planet's five known mass extincti...
14-03-13 A new NASA study shows Earth's climate likely will continue to warm during this century on track with previous estimates, despite the recent slowdown in the rate of global warming. This research hinges on a new and more detailed calculation of the s...
14-03-12 We live in a galaxy known as the Milky Way -- a vast conglomeration(聚集,团块) of 300 billion stars, planets whizzing around them, and clouds of gas and dust floating in between. Though it has long been known that the Milky Way and its orbiting c...
14-02-24 Researchers recently discovered that a common space weather phenomenon on the outskirts of Earth's magnetic bubble, the magnetosphere(磁气圈) , has much larger repercussions(反响,影响) for Venus. The giant explosions, called hot flow anomalies...
