—————————

Kuiper belt is a circumstellar disc in the outer Solar System, extending from the orbit of Neptune at 30 astronomical units (AU) to approximately 50 AU from the Sun. It is similar to the asteroid belt, but is far larger—20 times as wide and 20–200 times as massive. Like the asteroid belt, it consists mainly of small bodies or remnants from when the Solar System formed. While many asteroids are composed primarily of rock and metal, most Kuiper belt objects are composed largely of frozen volatiles (termed “ices”), such as methane, ammonia, and water. The Kuiper belt is home to most of the objects that astronomers generally accept as dwarf planets. Some of the Solar System’s moons, such as Neptune’s Triton and Saturn’s Phoebe, may have originated in the region. — Wikipedia

Technology

New Horizons is a space probe that was part of NASA’s New Frontiers program. Engineered by the Johns Hopkins University Applied Physics Laboratory (APL) and the Southwest Research Institute (SwRI), with a team led by Alan Stern, the spacecraft was launched in 2006 with the primary mission to perform a flyby study of the Pluto system in 2015, and a secondary mission to fly by and study one or more other Kuiper belt objects (KBOs) in the decade to follow, which became a mission to 486958 Arrokoth. It is the fifth space probe to achieve the escape velocity needed to leave the Solar System. — Wikipedia

History

In 1951, in a paper in Astrophysics: A Topical Symposium, Gerard Kuiper speculated on a similar disc having formed early in the Solar System’s evolution. — Wikipedia

Six massive landslides discovered on icy Pluto
on July 13, 2026 at 7:30 pm
Scientists have detected evidence of landslides on Pluto for the first time. A paper published in the journal Icarus reports that images taken by the New Horizons spacecraft during a flyby revealed six large landslides in three impact craters.

Where does the solar system end and interstellar space begin? That's a question scientists have been working to answer using spacecraft traveling beyond the sun's influence. A team of researchers from the Southwest Research Institute, led by Heather Elliott, is using the Solar Wind Around Pluto (SWAP) instrument aboard New Horizons to track the solar wind in the outer reaches of the solar system.
Did gravitational tides cause Earth's extinctions?
on June 25, 2026 at 12:00 am
Life on Earth took a long evolutionary journey that eventually created us, the purportedly intelligent species that dominates the planet. But there was no grand plan or design, only happenstance, nature and luck. Life on Earth suffered multiple extinctions, but got up, dusted itself off and continued on its long march to complexity.
How solar wind forecasting will help define...

Southwest Research Institute (SwRI) scientists are using a solar wind forecasting method combined with analytic and numerical heliosphere models to find out where the first plasma boundary of the outer heliosphere lies as NASA's New Horizons spacecraft hurtles toward this mysterious region of space.
