Using a simple model based on granular physics, like those used for modeling sand or sugar deposits, scientists have recreated the diamond shape of asteroids Ryugu and Bennu in computer simulations. Plus, the origins of loner dwarf galaxies and this week’s What’s Up.
Our Rocket Roundup is a launch bonanza, with launches from Arianespace, China, Blue Origin, Astra, SpaceX, and Firefly. Plus, this week in rocket history, we look back at the Luna 16 mission, which included the first successful robotic sample return from the Moon.
Hycean worlds have hydrogen-rich atmospheres and are covered in oceans, making them prime candidates for the search for life outside our own solar system. These worlds are also more numerous and easier to find than Earth-like exoplanets. Plus, an update on the search for Planet 9 and how volcanoes may provide a climate safety valve.
New research has pinpointed small, violent faults caused by the breakup of an ancient supercontinent as the potential cause of a major loss in the rock record of the Grand Canyon, known as the Great Unconformity. Plus, using sky mapping tools to find earthly tombs and a review of Andy Weir’s “Project Hail Mary.”
We’re talking about particle physics today! An effect called the “triangle singularity” has been observed, and it describes how particles change identities by exchanging quarks. Plus, climate change news, and in this week’s What’s Up, Jupiter is at opposition.
On this week’s Rocket Roundup, an ISRO rocket fails and Arianespace launches a big satellite. Plus, Boeing can’t seem to get their act together. And this week in rocket history, we look back at the first mission to explore all of the outer planets – Voyager 2.
