The so-called “great instability” event that sent gas giants careening through space until they settled into orbits occurred between 60 and 100 million years after the birth of the solar system. Migrating planets primarily Jupiter, it turns out, may have led to the formation of Earth’s moon. Live Science explains: https://flip.it/wWBTEy #Science#Space#Jupiter#Earth#Moon#SolarSystem
My #house started doing a madness and randomly, the #electric kept tripping and I was like WTF? So I kept trying to figure out what was happening and by process of elimination, worked out its something to do with the downstairs #sockets.
Everyday, it was becoming more and more frequent and I was getting more and more frustrated and stressed.
Fast forward to yesterday and I ordered a socket checker ASAP from Amazon, only to find out the #extension lead I plug into the plug next to my bed has no #earth and I sleep every night with a charger plugged into that extension on the edge of my bed.
Turns out the moon is not made of cheese, though it would have been a popular appetizer at your next dinner party. A thorough investigation revealed that Earth’s satellite has an inner core with a density similar to iron, which appears to settle the longstanding debate over it being solid or molten. There’s more in this Science Alert article, including how astronomers made the discovery and why it could lead to a better understanding of the solar system. https://flip.it/0nP7A1 #Science#Earth#Moon#Solar System #Space
