Gaze across the frozen canyons of northern Pluto in this contrast enhanced color scene, imaged last July by the New Horizons spacecraft. Currently known as Lowell Regio, the region has been informally named for Percival Lowell, founder of the Lowell Observatory. Also famous for his speculation that there were canals on Mars, in 1906 Lowell started the search that ultimately led to Pluto’s discovery. Pluto’s North Pole itself is above and left of center in the the frame. The pale bluish floor of the broad canyon on the left is about 70 kilometers (45 miles) wide, running vertically toward the south. Higher elevations take on a yellowish hue. New Horizon’s measurements have determined that in addition to nitrogen ice, methane ice is abundant across northern Pluto’s Lowell Regio.

在這個對比增強的色彩場景中，眺望北冥王星的冰凍峽谷，該畫面由新地平線號太空船於去年七月拍攝。目前這個地區被稱為Lowell Regio，非正式名稱來自於珀西瓦爾·洛威爾（Percival Lowell），他是洛威爾天文臺的創辦人。洛威爾以猜測火星上有運河而聞名，並於1906年開始進行尋找，最終導致冥王星的發現。冥王星的北極位於畫面的左上方。左側的寬闊峽谷地面呈現淺藍色，寬約70公里（45英里），向南垂直延伸。較高的地形呈現黃色調。新地平線號的測量結果顯示，除了氮冰外，甲烷冰在北冥王星的Lowell Regio也非常豐富。
