Hurricanes are regular visitors to the Walkabout Studios at the University of Central Florida, but not to the planet Venus, whose slow rotation makes for rather dull weather. High of 900 degrees is forecast for Venus for the foreseeable future. But there are some mysteries in its upper atmosphere. We'll also talk about the mysteries of quantum gravity, which doesn't exist yet, and the role of supernovae in starting planetary systems and evidence for a bunch of them popping off in our neighborhood recently. Plus space news and hurricane trivia!

Join us for a special musical episode of Walkabout the Galaxy with guest Adam LaMee as we take a look at a nearby giant exoplanet and a very distant supernova of a type that has never been seen before.

Astronomy and cosmology challenge our perceptions of space and time, make us ponder our place in the universe, and give us wonders from the infinitesimal to the nearly-infinite. Then there's Walkabout the Galaxy, where we attack the question of which is a bigger relative bite: when the Sun in its red giant phase swallows the Earth, or when Jim Cooney in his fishing phase swallows a gnat. For that and the other truly important questions, you can count on the Astroquarks. Walkabout the Galaxy: for the truly important questions in life.

We never get tired of Einstein being right, and once again his general theory of relativity is up to the challenge. The astroquarks take you on a tour to the black hole at the center of the Milky Way for another test of Einstein's theory of gravity, while closer to home the Japanese Hayabusa-2 mission has successfully grabbed some more asteroid rubble. Dr. Zoe Landsman, aka Beauty Astroquark, joins Josh and Jim on this walkabout with spaceships being propelled by sunlight, nerd news, and Apollo trivia.

A thousand bonus Trekkie points for getting the reference of the title of this episode, and another 1000 points for connecting it to our main science topic (spoiler alert): voids in space. Space is very empty, and some parts are emptier than others. Giant voids are helping us narrow down the rate of expansion of the universe. NPR's Brendan Byrne, space reporter for WMFE 90.7, joins us to give a peak behind the scenes of NASA's plans to send people to the Moon, plus some physics-y space trivia and much more.

Supermassive black holes lurk in nearly every galaxy, and stellar-mass black holes are making news with mergers that we see with our gravitational wave observatories. But what about the black hole middle class? And just how massive are these things anyway? Plus, Hollywood director and astroquark brother K.C. Colwell ("Deep Impact", "The Mummy", "The Wolverine", "The Walking Dead") joins the astroquarks to talk about science and special effects in movies. And we honor the 50th anniversary of the amazing achievement of Apollo 11 with bonus Apollo trivia.

We're going back to Saturn! NASA has selected the Dragonfly mission to the planet-moon Titan to explore its atmosphere and carbon-rich chemistry with a dual quadcopter capable of flying several km at a time. Work continues on the Europa Clipper mission to Jupiter's own Ocean World. The astroquarks catch you up on these new missions, plus some nerdy sci-fi trivia, Josh mangles French, and, as always, be sure to listen through to the end for a unique and surprising outro to the show.

There is no center of the universe, no top or bottom (except for our astroquarks!), but all sorts of things in the universe have a definite handedness, and this includes fundamental particles, whose left-ness or right-ness is captured in a quantum property called spin. Top astroquark Jim Cooney takes us for a spin around new results looking into why there is a preference for certain directions of spin. Closer to home we look into the spin of the early Sun and how it ties into the early evolution of life and rocks on the Moon! So take the universe for a spin with us, and get a tangential trivia and all your space news on Walkabout the Galaxy.

The universe began in a hot, dense state, as the song goes, and we can, oddly, see that heat from the thing that we are still in. The universe. Strange stuff. The radiation leftover form the big bang, known as the cosmic microwave background, or CMB, has cooled off, but analysis of measurements of this radiation by the Planck spacecraft point to some odd hot and cold halves of the universe. The astroquarks take a deep dive into the CMB, plus lots of new spaceflight news and of course your Walkabout trivia.

The astroquarks take a stroll through the extrasolar planetary zoo where there are new members of the close-to-Earth-sized club and a peculiar Neptune-y thingy orbiting super close to its star. Meanwhile there are rapid developments in NASA's renewed focus on sending astronauts to the Moon, and we revisit the strange case of quarks, anti-quarks, and the existence of matter in the universe. Plus a very deep dive into Forbidden Planet-inspired trivia.
