The astroquarks discuss news about lunar quakes and Venus… volcanoes. But volcanoes doesn’t rhyme with quakes, so I sacrificed alliteration for rhyming. Venus may be volcanically active, at least on relatively recent geological timescales. If only we could go back in time to see! Top quark Jim Cooney will bring us up to date on a new experiment that fiddles with the direction of time’s arrow. All that, plus space news and bonus trivia on this episode of Walkabout.
