The newly renamed object Arrokoth, once known as Ultima Thule, is ultrared, smooth and covered in organic complex molecules. New Horizons flew past the distant Kuiper Belt Object on January 1, 2019.

When NASA's New Horizons spacecraft flew past Pluto in July 2015, it captured this image of the major mountain ranges where it meets a vast icy plain called Sputnik Planitia. The ridges in these photos have now been identified as dunes made of solid methane ice grains.

New Horizons photographed what scientists are calling "bladed" terrain near the heart-shaped region of the dwarf planet. This 3-D image was created using two images taken about 14 minutes apart on July 14. The first image was snapped about 16,000 miles (25,000 kilometers) from Pluto and the second was taken when the spacecraft was 10,000 miles (about 17,000 kilometers) away. Break out your 3-D glasses for the best view.

The New Horizons team has discovered a chain of exotic mountains that are covered in methane snow on Pluto. NASA released an image of the snow-capped mountains stretching across the dark expanse of Cthulhu on March 3.

NASA released a photo on February 4, 2015, of what it suspects is an image of floating hills on Pluto's surface. The hills are made of water ice and are suspended above a sea of nitrogen.

This image made in infrared light shows water ice is abundant on Pluto's surface. The image was created using two scans of Pluto made by the New Horizons spacecraft on July 14, when the probe was about 67,000 miles (108,000 kilometers) above Pluto.

This image shows the layered interior walls of the planet's many craters. According to NASA, "layers in geology usually mean an important change in composition or event." However, NASA says the New Horizons team members do not know if they are seeing local, regional or global layering.<br />Most of the craters seen here lie within the 155-mile (250-kilometer)-wide Burney Basin. <a href="http://www.nasa.gov/image-feature/plutos-layered-craters-and-icy-plains" target="_blank">Learn more at NASA's website.</a>
