    Back to Venus with Several Rants

    Back to Venus with Several Rants

    We're feeling happy, chatty, and ranty in the first show back in our studio since February, 2020, with a look at two new missions to Venus, a cool experiment about Aurora, magnetic field trivia, and so much more.

    How the Universe has Aged

    How the Universe has Aged

    On our 239th episode the Astroquarks reflect on the Friends Reunion where they reflected on their time making only 236 episodes. The Friends and the Astroquarks have aged, but nothing compared to the Universe. We take a look at the first results from an ambitious all-sky survey to compare the distribution of matter in the universe today to what is predicted from our baby pictures of the universe. The results are a bit surprising. Also surprising: our helicopter trivia.

    Of Cosmic Rays and Neptune's Wandering Ways

    Of Cosmic Rays and Neptune's Wandering Ways

    Neptune, as the outermost big planet, has an outsized effect on the countless objects in the Kuiper belt in the distant reaches of the solar system. We take a look at how the orbits of Kuiper belt comets today can teach us about Neptune's orbit 4 billion years ago, which is pretty cool if you think about it, and even if you don't. We also get a clue that cosmic rays may come from supernovae, including one in our own galactic back yard. Get all this and top quark trivia on this episode of WtG.

    Ten Things I Hate About Neutrinos

    Ten Things I Hate About Neutrinos

    We are kidding, neutrinos. We love you. You're just a little bit scary! In this episode we discuss a way we'll learn about the mysterious tiny particles and their interactions with matter, as well as new spacecraft observations of the Sun, and a black hole caught in the act of spaghettification of a nearby star. Plus: special neutrino trivia from Top astroquark!

    Surprises at the Centers of Things

    Surprises at the Centers of Things

    How many licks does it take to get to the center of Saturn? We don't know, but when you get there you will find a gooey surprise. Saturn's core is more massive than previously thought, and has a mixing transition to the gases above, revealed by studying Saturn's rings of all things. Meanwhile the center of the galaxy has an odd source of antimatter. Learn about all that, giant telescopes, and upcoming missions on Walkabout the Galaxy.

    A Whirl of Neutron Stars

    A Whirl of Neutron Stars

    A quackery of astroquarks takes a close look at neutron stars thanks to observations from the NICER observatory on the International Space Station and some clever scientific modeling that reveals these rapidly spinning stellar remnants are not too soft, not too stiff, but just the right amount of squeezable. Join us to find out the hidden mysteries of neutron stars, and just what do you call a group of black holes, anyway? Get the answers to all this and more on Walkabout the Galaxy.

As wholesome as π

So good. I always look forward to Wednesdays now (when this show drops).
The show is nerdalicious

I couldn't delete it

I haven't been listening to podcasts during the pandemic times as much as I used to, when they helped me through rush hour traffic. I had over 2,000 hours built up so I had to start deleting and unsubscribing whole swaths of science podcasts that I had been devoted to for years. I heard about WTG from the Are We There Yet podcast and subscribed in 2019.

This is one I couldn't delete and I think the reason why is that it is good hardcore science provided in a fun way, like a good conversation among friends. With no pandering to the public. So it's a keeper for me.

I guess I've been listening to podcasts for 10 years. I've only written 3 reviews. THIS is #3.

Oh and my contribution to a name for a group of black holes: The Well of Holes.

Entertaining and informative

Been listening since almost the beginning. Very entertaining and informative. Love the three hosts’ chemistry. I usually get bored and move on to another podcasts.
