Walkabout the Galaxy

An ambitious Japanese mission, Hayabusa-2 has arrived at its target asteroid Ryugu. Are-you-good with that? See what we did there? (Ryugu'd? Get it?) Yes, that's the level of discourse on Walkabout the Galaxy, but we also find out about the great science to come from this exciting asteroid sample return mission, and a look ahead to the James Webb Space Telescope, whose launch has been slipped to make absolutely sure that nothing got Ryugu'd while building it. Plus we talk about the science of learning, and un-learning, with our special guest Anna Turner.

NASA does many inspiring and amazing things, from fundamental research into the evolution of the universe and the formation of planetary systems, to development of new technologies to enable humans to go to other worlds. They also sponsor research to monitor the Earth and to monitor the space near the Earth for potential impactors. The astroquarks weigh in on their own preferences for NASA's research priorities and discuss the results of a new survey of Americans on the subject. There's also the discovery of new weird stellar objects near the Milky Way's supermassive black hole, updates on Mars' early climate, and space trivia as always!

The astroquarks have often wondered where all our alien friends are hanging out. Maybe they're all just in a different universe? Well, most of those universes are probably duds, and anyway, we'll never know! That's the whole definition of a universe. New research sheds light on the surprisingly small role dark energy plays in the early evolution of a universe, and then there's the question of AntMan and the Wasp: do they conserve mass or not when they shrink? We must know!
