Over the past decade, researchers have been puzzling through Pluto’s mysteries. Meanwhile, the New Horizons probe heads for interstellar space.

Kuiper Belt Object Arrokoth, the farthest object ever explored by a spacecraft, likely tastes sweet — and soapy.

The surface of Arrokoth is probably laden is with the chemical building blocks for life — and that's pretty sweet. But please do not lick.

A new study from researchers at the Southwest Research Institute has unearthed a fascinating discovery about Arrokoth, a trans-Neptunian object made famous by the New Horizons probe in 2020.

Arrokoth is a planetesimal in the Kuiper Belt, a vast stretch of space beyond Neptune that holds remnant building blocks of the solar system leftover from our cosmic neighborhood's formation.

Mounds On Distant World Arrokoth Open A Window On How It Formed The Kuiper Belt object might have been forged from slightly smaller chunks.

A new study posits that the large, approximately 5-kilometer-long mounds that dominate the appearance of the larger lobe of the pristine Kuiper Belt object Arrokoth are similar enough to suggest a ...

The large mound structures that dominate one of the lobes of the Kuiper belt object Arrokoth are similar enough to suggest a common origin – SwRI.

The map of a distant, lobe-shaped object called Arrokoth (2014 MU69) now has official names to accompany the images from NASA's New Horizons spacecraft. After the spacecraft zoomed by the lobe ...

His Arrokoth display at Tinney borrows its name from the most remote celestial object ever visited by a spacecraft, and the press release image for the show — a dimly lit photo of one of Harding ...

Arrokoth is among countless objects in the so-called Kuiper Belt, or vast Twilight Zone beyond the orbit of Neptune.
