NASA’s New Horizons spacecraft sent this image of Pluto taken on July 13, 2015, when the spacecraft was still almost half a million miles (768,000 kilometers) from the surface. The view is dominated by a large, bright heart-shaped feature, now unofficially named the Tombaugh Regio in honor of the American astronomer who discovered Pluto in 1930. The feature measures approximately 1,000 miles (1,600 km) across. Credits: NASA/APL/SwRI
