Are the Earth’s magnetic poles about to swap places?
Earth’s previous polar reversal happened 780,000 years ago. Are we facing another one soon? Hear from the authors of a new study, on a strange anomaly that might be a clue. Source: https://earthsky.org/earth/earths-magnetic-poles-reversal-soon-study…

Mars Is a Seismically Active World, First Results From NASA’s InSight Lander Reveal
The first results from NASA’s quake-hunting InSight Mars lander just came out, and they reveal that Mars is a seismically active planet. Space.com reports: Martian seismicity falls between that of the moon and that of Earth, [says InSight principal investigator Bruce Banerdt, of NASA’s Jet Propulsion Laboratory]. “In fact, it’s probably close to the kind of seismic activity you would expect…
