It took several million years for Arrokothn to acquire its bizarre, pancake-flat shape

The trans-Neptunian object Arrokoth, also known as Ultima Thule, which NASA’s space probe New Horizons passed on New Year’s Day 2019, may have changed its shape significantly in the first 100 million years since its formation. In today’s issue of the journal Nature Astronomy, researchers led by the Chinese Academy of Sciences and the Max Planck Institute for Solar System Research…

Subaru Telescope and New Horizons explore the outer solar system

Collaborative observations with NASA’s New Horizons mission have been ongoing at the Subaru Telescope since May 2020. Hyper Suprime-Cam (HSC), the wide field camera mounted on the prime focus of the Subaru Telescope, is used for the observations to search for target candidates for New Horizons’ next observations. Astronomers from Japan are participating in the observation team together with ones from…

10 cool things we learned about Pluto from New Horizons

Five years ago today, NASA’s New Horizons spacecraft made history. After a voyage of nearly 10 years and more than 3 billion miles, the intrepid piano-sized probe flew within 7,800 miles of Pluto. For the first time ever, we saw the surface of this distant world in spectacular, colored detail. Source: https://phys.org/news/2020-07-cool-pluto-horizons.html…
