After Pluto, Where Will NASA's New Horizons Go?

Scientists are mulling over which of two icy bodies NASA's New Horizons spacecraft should visit following its Pluto encounter this summer — provided the U.S. space agency comes up with funding for an extended mission. » 3/22/15 9:30am 3/22/15 9:30am

The Complete History Of Ceres, The Planet (?) Between Mars And Jupiter

Over the last couple of weeks, the Dawn Spacecraft has been beaming back spectacular pictures of Ceres – a world, discovered more than a century before Pluto, about which we know very little. This is the story of its discovery, and humanity's impending visit to one of the last unexplored planetary bodies in the… » 2/23/15 11:00am 2/23/15 11:00am

Meet Nix And Hydra, The Tiny Moons Of Pluto

Eighty-five years ago today, Clyde Tombaugh found a small dot of light shifting position while hunting for the trans-Neptune planet predicted by Percival Lowell. Now, the New Horizons probe en route to Pluto has photographed its tiny moons, Nix and Hydra. » 2/19/15 1:03am 2/19/15 1:03am

The Closest View Yet Of Charon Orbiting Pluto

The New Horizons spacecraft has beamed back a time-lapse "movie" showing an entire day in the Pluto-Charon system. Captured from a distance of just 126 million miles (203-million km), the footage clearly depicts the "wobble" imposed on the dwarf planet by its large moon. » 2/12/15 11:20am 2/12/15 11:20am

Our First Grainy Glimpse Of Pluto And Charon As New Horizons Closes In

NASA's New Horizons has returned its first images of Pluto and its largest moon, Charon, since the mission entered into the countdown phase of its historic mission. Taken at a distance of 126 million miles (200 million km), it will pale in comparison to the images expected over the coming months. » 2/05/15 6:30am 2/05/15 6:30am

New Horizons' Historic Pluto Encounter Has Officially Begun

We are 179 days away from New Horizon's closest approach to Pluto, but that doesn't mean the NASA spacecraft will be twiddling its robotic thumbs until then. As of today, it's starting to record precious data about this mysterious dwarf planet and its surroundings. » 1/15/15 4:00pm 1/15/15 4:00pm

These Are The Science Stories That Will Be Making News In 2015

The coming year is shaping up to be a rather extraordinary one. Over the next 12 months, we'll be visiting dwarf planets, unlocking the secrets of a 400,000-year-old genome, and resuming the hunt for exotic particles.

Images of Charon Orbiting Pluto Guide A Spacecraft To Its Destination

An animation of Pluto and its largest moon, Charon, was created using a series of images captured by the New Horizons spacecraft as it continues its long journey to the distant planetoid. Taken from a distance of 422-429 million km, the images are not for scientific study, but for optical navigation between worlds. » 8/07/14 2:40pm 8/07/14 2:40pm

New message to aliens could be uploaded to New Horizons spacecraft

Astronomical artist Jon Lomberg — the same guy who helped develop the Voyager Interstellar record back in 1977 — is launching a new initiative to persuade NASA to upload a new message to the New Horizons spacecraft once its mission to Pluto is complete. He's calling it Voyager Record 2.0. » 9/20/13 6:20am 9/20/13 6:20am
