Kuiper belt News

The New Horizons flyby of Ultima Thule is expected to help scientists better understand what conditions were like when our solar system formed billions of years ago.

Super-Earth (Planet Nine) is a world '10 times the mass of Earth and 20 times farther from the sun than Neptune.'

The new images released by NASA on Thursday were captured by New Horizons when the spacecraft was more than 6.12 billion km away.

 In other words, something unknown is warping the average orbital plane of the outer solar system.

 The team uncovered the moon in archival images of 2007 OR10 taken by the Hubble Telescope.

NASA's SOFIA, the world's largest airborne astronomical observatory, recently completed a detailed study of this nearby planetary system.

The video offers a trip down onto the surface of Pluto - starting with a distant view of Pluto and its largest moon, Charon - and leading up to an eventual ride in for a "landing" on the shoreline of Pluto's informally named Sputnik Planitia.

The New Horizons mission team has received the green light to fly onward to an object deeper in the Kuiper Belt.

When New Horizons buzzed by Pluto last year, it unveiled clues that the dwarf planet might have - or had at one time - a sub-surface liquid ocean.

The yet undiscovered 'Planet X' may trigger comet showers linked to mass extinctions on our planet, say researchers.

Scientists reported today they finally have "good evidence" for Planet X, a true ninth planet on the fringes of our solar system. The gas giant is thought to be almost as big as Neptune and orbiting billions of miles beyond Neptune's path, distant enough to take 10,000 to 20,000 years to circle the sun.

The Long Range Reconnaissance Imager (LORRI) instrument on NASA’s New Horizons spacecraft captured four low-resolution images of 1994 JR1 object.

The spacecraft that gave us the first close-up views of Pluto now has a much smaller object in its sights.
