Comet Catalina is ready for its close-up. The giant snowball from the outer Solar System, known formally as C/2013 US10 (Catalina), rounded the Sun last month and is now headed for its closest approach to Earth in January. With the glow of the Moon now also out of the way, morning observers in Earth’s northern hemisphere are getting their best ever view of the new comet. And Comet Catalina is not disappointing. Although not as bright as early predictions, the comet is sporting both dust (lower left) and ion (upper right) tails, making it an impressive object for binoculars and long-exposure cameras. The featured image was taken last week from the Canary Islands, off the northwest coast of Africa. Sky enthusiasts around the world will surely be tracking the comet over the next few months to see how it evolves. Follow APOD on: Facebook, Google Plus, or Twitter

🌌 彗星Catalina正準備好接受拍攝！這顆來自外太陽系的巨大冰雪球，正式名稱為C/2013 US10 (Catalina)，在上個月曾經繞過太陽，現在正朝著1月份與地球的最近接觸邁進。隨著月光的影響已經減少，北半球的早晨觀察者獲得了前所未有的觀賞機會。彗星Catalina並沒有令大家失望。儘管光度未如早期預測般亮眼，這顆彗星展現了壯觀的塵埃（左下）和離子（右上）尾巴，成為雙筒望遠鏡和長時間曝光相機的絕佳觀察對象。這幅圖片是上周在非洲西北海岸的加那利群島拍攝的。全世界的天文愛好者肯定會在接下來幾個月跟蹤這顆彗星，看看它的變化。
