New Horizons

NASA's New Horizons spacecraft will get three times closer to its next flyby target than it got to Pluto back in July 2015, if all goes according to plan.

NASA's New Horizons spacecraft could end up carrying a message for intelligent aliens, just like the agency's venerable Voyager probes are doing.

The New Horizons spacecraft's next flyby target blocked the light of an unnamed star on July 17, and mission scientists got a great look at the brief event.

You can relive New Horizons' epic Pluto flyby, thanks to two amazing videos NASA released Friday (July 14), the two-year anniversary of the landmark event.

On July 14, 2015, NASA's New Horizons spacecraft zoomed within 7,800 miles (12,550 kilometers) of Pluto, capturing the first-ever up-close looks at the dwarf planet system.

In a new experiment, researchers have created a super-dense version of ice found deep within icy moons and colliding comets, and watched it form in nanoseconds.

The team behind the New Horizons mission to Pluto recently pulled of a challenging observation of the spacecraft's next target, MU69, as the object eclipsed a distant star.

New Horizons, which performed the first-ever flyby of Pluto on July 14, 2015, entered hibernation Monday afternoon (April 10) for the first time in nearly 2.5 years, mission team members said.

Saturn's rings appear as bright waves against a black sky in detailed new pictures from the Cassini spacecraft, which made its closest pass by the icy debris in years.
