Farewell to Cassini
再见,卡西尼号
We learned about the power of human ingenuity in our solar system’s deep reaches.
抵达太阳系深处的人类智慧。
The Cassini spacecraft has been sending home images of Saturn, its rings and its moons since arriving at the gas giant in 2004. The mission ended in September with a planned fiery crash into Saturn’s atmosphere. While it studied the planet, Cassini explored moons — Titan and Enceladus — that could be home to extraterrestrial life. The probe also gave us great insight into our solar system, and will continue to do so for years as scientists pore over the data it collected.
自2004年抵达土星以来,卡西尼号宇宙飞船已经将土星、土星环及土星卫星的图片传送回地球。卡西尼号于9月完成使命,按计划撞向土星大气层中焚毁。卡西尼号在研究土星的同时,还探索了可能存在外星生命的土卫六和土卫二。它使人们更加深入地了解了太阳系,这种影响还将持续,科学家将继续对它收集的数据进行分析。
Beauty and Evolution
美与进化
We learned that animals may make choices based on aesthetics.
动物会根据美感做出选择。
Why does beauty exist? To answer this question, Richard O. Prum, an ornithologist, is working to revive an idea advanced by Charles Darwin: the attractiveness of an animal to another of its species isn’t only tied to fitness and good genes. Rather, animals — especially birds in Dr. Prum’s work — are making subjective decisions. He hopes that evolutionary biologists will stop “explaining away desire.”
