2015 年 7 月，经过了九年的艰苦跋涉，新视野号探测器终于飞越冥王星，得以看到它的庐山真面目，成为人类首颗造访冥王星的探测器。发回的照片，让无数期待已久的地球人感动不已。Famed astronomer Percival Lowell began searching for “Planet X” in 1906, but died 10 years later, not realizing he’d actually spotted Pluto. In 1929, a 23-year-old astronomer named Clyde Tombaugh came to work at Lowell Observatory in Flagstaff, Arizona, and was assigned the task of picking up where Lowell left off. And on this day in 1930, Tombaugh confirmed that beyond Neptune there was a ninth planet, soon to be named Pluto. (In 2006, Pluto’s status was demoted to “dwarf planet.”)
NASA’s New Horizons space probe launched in early 2006 on a mission to travel to Pluto, orbit it, collect data, and transmit its findings back to Earth. New Horizons took its first images of Pluto just months after launch from more than 2.6 billion miles away. But by early 2015, the probe had traveled close enough to Pluto that it was able to take highly detailed images of our favorite dwarf planet. Now more than 10 years into its mission, New Horizons has been offering up a treasure trove of findings for astronomers to study. The colors in this shot have been enhanced to bring out the detail of Pluto’s surface.
