文章賞析

• Your Guide to Pluto: Everything We’ve Learned From New Horizons So Far
  冥王星導覽：目前我們從新視野號所得知的種種
• New ideas about Pluto, Charon, and all the little moons have been flowing back from the New Horizons spacecraft fast and furious. If you’re curious but haven’t kept up, here’s everything we’ve learned so far.
  關於冥王星、凱龍星與所有小月亮們的觀測消息都火速從新視野號傳回來。倘若你很好奇，又還沒跟進，以下有目前最新的消息。
• The New Horizons spacecraft is on a decade-long mission exploring deep space. It just completed the first-ever flyby of Pluto, a dwarf planet and the first Kuiper Belt Object ever explored. The spacecraft can either make observations or communicate with Earth, so for now it’s focusing on getting more data and sending back just the barest, highest-priority data in its failsafe downlinks. Even that tiny trickle of data has been enough to completely overthrow our theories of what we expected to find at the icy little world and its family of moons.
  新視野號正在執行長達10年的任務探索外太空。它完成了史上首度飛掠冥王星-這個矮行星，以及進行柯伊伯帶天體之探索。這個太空船可進行觀察或與地球連繫，此時它專注著獲取更多數據，採用萬無一失的向地面傳輸方式，將最赤裸、最優先的資料傳回來。就算是極微小的點滴數據，都足以完全顛覆我們原先預期在這個冰球與它的月亮家族上發現出什麼的理論，
• Instead, the New Horizons spacecraft specifically targeted the bright heart of Pluto (named Tombaugh Regio for discoverer Clyde Tombaugh) for its close-up photographs.The most shocking part of Pluto is that we’ve found far fewer craters than we’d expected. In all the close-up images released so far of the Tombaugh Regio, we haven’t seen a single crater. Instead of an ancient, inert rock, we’ve found a icy world with active processes creating fresh surfaces within the past 100 million years. (That’s younger than the Appalachian Mountains!)
  新視野號反而特地鎖定冥王星的明亮心型區(稱之為湯博區，用發現者克萊德‧湯博命名)獲取特寫照片。最令人驚奇的是我們發現冥王星的坑洞比預期少很多。在目前所發布的湯博區特寫照片中，我們沒有看到任何坑洞。我們發現這個冰凍世界在過去一億年內有活躍運作製造出新的表面層，而不是個古老的死星(還比阿帕拉契山脈年輕喔!)。
