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

Up until 2016, you couldn’t buy a copy, but then Ozma Records ran a brilliant Kickstarter campaign to issue a limited vinyl edition. Here’s a link to a video … Continue reading A Golden Gift
Great Views of Earth - April 22nd is Earth Day! In honor of that, here are some great ways to see the honoree. First, you can get a nice view from this neat 360° Video from Seeker. It essentially shows you what it would feel like if you could just fly straight up and see the Earth from space. Seeker … Continue reading Great Views of Earth
Space Rocks! - NASA engineers had quite a New Years celebration in 2019 when New Horizons successfully executed a flyby of a tiny object named 2014 MU69 while moving at 32,000 miles per hour. The planetesimal 2014 MU69 is better known by it’s nickname Ultima Thule, and it’s located way out past Pluto in a region of the … Continue reading Space Rocks!

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

Neptune's tiny moons tell the story of Triton's...
on August 15, 2026 at 3:20 pm
Neptune's moon and ring system stand out among the giant planets because of the strange imbalance between its one very large moon and its many tiny moons. Its largest moon, Triton, makes up more than 99% of the mass of all satellites orbiting the planet while orbiting retrograde compared with Neptune's rotation. The predominant theory is that Triton is a captured Kuiper Belt object that caused a major disruption in Neptune's early moon system. Now, a new study published in Science Advances […]
The asteroid that may be three worlds
on August 9, 2026 at 10:40 am
What shape is an asteroid? For (44) Nysa, the honest answer until now has been that nobody knew. It is one of the brightest and largest E-type asteroids in the main belt, a class with a surface rich in enstatite, and its oddness has made it a favorite target for well over a hundred years. Successive observations hinted that it was elongated, perhaps even two lumps stuck together, but the picture stayed frustratingly blurred.
Liquid nitrogen may have recently flowed across...
on August 6, 2026 at 1:00 pm
A new study led by Southwest Research Institute (SwRI) provides evidence that liquid nitrogen is rising to Pluto's surface through cracks at the northern edge of Sputnik Planitia, part of the massive heart-shaped glacier on the dwarf planet's surface. This is the first evidence of liquid flow occurring recently on Pluto. The study is based on data from NASA's New Horizons spacecraft and led by SwRI Associate Vice President Dr. Alan Stern, the principal investigator of the New Horizons mission.

In 1989, the Voyager 2 mission discovered six new moons orbiting Neptune, including five tiny ones that orbit just outside the planet's main rings. Because of their small sizes and locations, these satellites have been difficult to study from Earth. Now, using NASA's James Webb Space Telescope (JWST), a team of Caltech researchers has observed Neptune's rings and three of those moons—Larissa, Galatea and Proteus—and found that their composition is unique among outer solar system bodies.
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.
