凝视冥王星北部的冰冻峡谷，这张色彩对比增强的照片。用于构建它的图像数据是2015年7月由新视野号宇宙飞船获得的，当时它首次侦察飞行穿过距离太阳60亿公里的遥远冥王星系统。这个地区现在被称为洛厄尔地区，是以洛厄尔天文台的创始人珀西瓦尔·洛厄尔的名字命名的。洛厄尔也因他猜测火星上有运河而闻名，他开始了一项研究，最终导致克莱德·汤博在1930年发现了冥王星。在这幅图中，冥王星的北极位于中间偏左的上方。左边宽阔的峡谷底部呈淡蓝色，宽约70公里（45英里），垂直向南延伸。较高的海拔呈现淡黄色。“新地平线”号的测量结果被用来确定，除了氮冰之外，洛厄尔地区还存在大量甲烷冰。迄今为止，冥王星是太阳系中唯一一颗由11岁女孩命名的行星。

Gaze across the frozen canyons of northern Pluto in this contrast enhanced color scene. The image data used to construct it was acquired in July 2015 by the New Horizons spacecraft as it made the first reconnaissance flight through the remote Pluto system six billion kilometers from the Sun. Now known as Lowell Regio, the region was named for Percival Lowell, founder of the Lowell Observatory. Also famous for his speculation that there were canals on Mars, Lowell started the search that ultimately led to Pluto's discovery in 1930 by Clyde Tombaugh. In this frame Pluto's North Pole is above and left of center. 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 were used to determine that in addition to nitrogen ice, methane ice is abundant across Lowell Regio. So far, Pluto is the only Solar System world named by an 11-year-old girl.
