Walkabout the Galaxy
lunar quakes, Venus volcanoes
Astrophysics and Astronomy | Physics
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.
Whether you crave sunshine or you're a real night owl, Shackleton Crater is the place for you. Situated on the Moon's rotation axis in the welcoming south polar region, Shackleton Crater is open for business with sunshine 709-12.4. That's right, the sun shines on the crater rim 709 hours per day, 12.4 days per year, while you're just a short hop, skip, and a lunar-gravity jump away from perpetual darkness at the crater floor where you can stretch out on your moon blanket and gaze at the stars in the ink-black sky without fear of getting blinded by the Sun or those pesky radio signals from Earth to make sure you're still alive. Shackleton Crater: let's build something together.
