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 on New Year’s Day ...

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 ...

SPACE — More than a year after NASA’s New Horizons mission closely flew by a small, distant Kuiper Belt Object, researchers have been able to sift through the data and learn intriguing new details ...

Nothing you encounter is truly “pristine.” Nearly every atom on our planet has been processed in some way, either by humans, the Sun, Earth’s core, or other influences. But on New Year’s Day 2019, the ...

This time last year, the New Horizons mission visited the furthest object humanity has ever reached — Arrokoth, beyond the orbit of Pluto in an area called the Kuiper Belt. Now, scientists have ...

Primitive ices and gas from the earliest days of the solar system can remain trapped inside deep-space objects like comets and Kuiper Belt Objects (KBOs) for billions of years. That’s the conclusion ...

Researchers found that the double-lobed object, which is officially named Kuiper Belt Object 486958 Arrokoth and resembles a snowman, may have ancient ices stored deep within it from when the object ...

NASA’s New Horizons spacecraft zoomed past a city-sized object just over a year ago. The most distant object ever explored, since named Arrokoth, was a “planetesimal” lurking quietly in the outer ...

A new study led by Southwest Research Institute (SwRI) Planetary Scientist and Associate Vice President Dr. Alan Stern posits that the large, approximately 5-kilometer-long mounds that dominate the ...

The large mound structures that dominate one of the lobes of the Kuiper belt object Arrokoth are similar enough to suggest a common origin, according to a new study led by Southwest Research Institute ...
