The intriguing bright spots on dwarf planet/asteroid Ceres have been fascinating the public and scientists alike for the past few months, and […]

New Spectacular Images of Pluto From New Horizons Reveal an Exotic, Dynamic World

A breathtaking, dramatic image of Pluto backlit by the distant Sun, taken by NASA’s New Horizons spacecraft a few hours after its closest approach, on July 14, while at a distance of 2 million km away from the planet. Besides its unparalleled aesthetic quality, this image provided scientists with important information about the structure […]

Historic First Close-Ups From New Horizons Reveals Dramatic Worlds Billions of Miles Away

Pluto’s largest moon Charon (left) has a surprising youthful and varied terrain, with cliffs, troughs, and a dark marking nicknamed “Mordor” in the moon’s north polar region. New close-up images of a region near Pluto’s equator (right) reveal a giant surprise: a range of youthful mountains rising as high as 11,000 feet (3,500 meters) […]

In Just a Few Hours, New Horizons Will Fulfill Its Destiny With First Up-Close Exploration of Pluto

On July 11, 2015, New Horizons captured a world that is growing more fascinating by the day. For the first time on Pluto, this view reveals linear features that may be cliffs, as well as a circular feature that could be an impact crater. Rotating into view is the bright heart-shaped feature that will be seen in more detail during New Horizons’ closest approach on July 14. The annotated version includes a diagram indicating Pluto’s north pole, equator, and central meridian. Credits: NASA/JHUAPL/SWRI

A portrait from the final approach. Pluto and Charon display striking color and brightness contrast in this composite image from July 11, showing high-resolution black-and-white LORRI images colorized with Ralph data collected from the last rotation of Pluto. Color data being returned by the spacecraft now will update these images, bringing color contrast into […]

One Day to Pluto: Looking Back at Humanity's First-Time Successful Encounters With the Sun's Planets

We’re nearly there.

Eighty-five years after it was first identified by U.S. astronomer Clyde Tombaugh and subsequently named by English schoolgirl Venetia Burney, 39 years since its surface was first […]

Two Days Prior to Closest Approach New Horizons Images Pluto's Charon-Facing Hemisphere for the Last Time

Pluto’s Charon-facing hemisphere, as seen by the New Horizons spacecraft for the last time on july 11, from a distance of 4 million km away. The image clearly shows newly-resolved linear features above the equatorial region that intersect, suggestive of polygonal shapes. Image Credit/Caption: NASA/JHUAPL/SWRI

With just two days remaining before New Horizons zips […]
