Here’s a taste of what New Horizons hopes to resolve when it passes by Pluto next Tuesday, July 14th.
Sunlight on Pluto is only a thousandth as strong as it is here on Earth. With careful timing, you can experience what it'd be like to stand on Pluto at noon.
At opposition this week and as bright as it will be for the next 190 years, it's time to find your way to Pluto, a frigid enigma at the edge of night.
How will planetary scientists decide what to call the features they discover on Pluto and its moons?
Right on cue, New Horizons spacecraft has awakened from its final electronic hibernation. Seven months from now, it will make the first-ever visit to Pluto.
NASA’s New Horizons spacecraft whizzed by Pluto this morning just before 8 a.m. EDT at nearly 14 km/s (31,000 mph), about 12,500 km (7,750 miles) above the surface.
New Horizons flew past Pluto and its moons earlier today, but the spacecraft stayed out of contact with Earth while finishing its historic observations.
In the first of a series of installments written exclusively for Sky & Telescope, New Horizons principal investigator Alan Stern offers his behind-the-scenes perspective on what it took to get the spacecraft to Pluto.
New Horizons will reach Pluto a year from today, and the scientific community is abuzz with speculation about what the space probe might see when it gets there. Meanwhile, the New Horizons team scours the skies for a Kuiper Belt Object that New Horizons can visit after its Pluto flyby.
In a mission filled with surprises, New Horizons spacecraft has left its scientists awed by the array of landforms and compositions found on Pluto and Charon.
With just one day remaining until New Horizons makes its historic flyby, missions scientists are amazed by the views of Pluto and Charon already in hand.
This image series, taken by NASA’s New Horizons spacecraft in late January 2015, reveals the dwarf planet Pluto and its largest moon, Charon, orbiting their common center of mass.
New data on Pluto’s moons show that the system is more bizarre than previously thought.
In his second "insider blog" about the New Horizons mission, principle investigator Alan Stern offers a look at what we might find at Pluto. It sounds like science fiction, but it's not: NASA's New Horizons spacecraft is on final approach to the Pluto system! After 112 months in flight, the fastest spacecraft ever launched is…
Sometimes, it's just as exciting to watch a celestial object fade or disappear as it is to see it explode. We celebrate the "return" of a mysterious variable star and prepare for Pluto to occult a star.
It’s been a fantastic year for Pluto, and it’s only going to get more so. What better time to make your first (or second!) attempt at spotting the dwarf planet? Read on for a few tips to help you locate this dim object in the summer sky.
Despite an 11th-hour scramble due to an unexpected in predictions, NASA's flying observatory was in the right place at the right time on June 29th as distant Pluto briefly covered a 12th-magnitude star.
New images from NASA's New Horizons spacecraft reveal an ice-covered plain on Pluto that looks remarkably young and fresh.
