What If We Lost Our Moon?
2013 04 26
By Larry O’Hanlon | Discovery News
Today I was asked a question that was motivated by the new movie Oblivion: What would happen to the Earth if the moon was destroyed? “I dunno,” I replied, “What does happen when the moon is destroyed?” When the expected why-the-chicken-crossed-the-road response didn’t come, I decided I’d better try and answer the question.
The first thing that came to mind is that it depends on the manner of the moon’s destruction. If it was, say, zapped to bits by a Death Star and those bits still floated in a cluster in the same orbit, I expect they would exert the same gravitational pull on Earth as does the intact moon, and not much would change on Earth.
We’d no longer watch the phases of the moon at night, but see a glittering cloud of debris which would probably be a lot brighter than the full moon, what with all those zillions of little surfaces to reflect sunlight. I know some astronomers who would really hate this new interference with their dark skies.
But if the moon were dragged off and completely removed, there would be none of its mass left to tug gravitationally on the Earth. One of the effects would be that we could throw out tide tables for good.
The ocean tides would still happen, but the bulge of water would follow the sun, so you could expect high tides around noon everywhere, everyday. I know some fishermen who would appreciate this.
Since the solid Earth flexes tidally, it makes sense that there might be some internal grumbling when Earth loses the moon. Earthquakes. Maybe a few volcanoes getting rowdy. That kind of stuff. But there’s no reason to worry (or hope) that California will fall into the Pacific. Sorry New York. Sorry Las Vegas.
The greater concern would be in the long-term, regarding the Earth’s wobbling spin axis. Right now the spin axis of the Earth very slowly wobbles over 26,000 years, like a slowing wobbling top, because of the tug of the sun. The wobble causes true north to not always point at Polaris, a.k.a., the North Star. Experts agree that the moon acts sort of like a shock absorber to this wobble — keeping it from getting out of hand (see the nitty gritty details in this SETI talk).
It’s possible that Earth without a moon would wobble wildly, sort of like Mars does. The Red Planet’s wobble is so extreme that it may be the cause of some cycles of climate change there. If the same thing happened here, Earth might wobble so much that seasons would become inhospitably extreme and Earth would be a much less stable and habitable planet.

Talk about a precious stone — the largest piece of the only known meteorite from the planet Mercury has found its way to Yale, where it is now on display at the Peabody Museum of Natural History.
Known as NWA 7325, the fist-size, greenish space rock is a rarity among rarities: there just aren’t many verified planetary meteorites. Scientists know ...
US general who opened Guantanamo prison says shut it down
2013 12 12
The US general who opened the notorious US-run Guantanamo prison says it was a mistake and it should be shut down because the prison complex "validates every negative perception of the United States."
"In retrospect, the entire detention and interrogation strategy was wrong," Marine Major General Michael Lehnert wrote in the Detroit Free Press on Thursday.
Lehnert was the first commander of ...

Cassini spies mysterious object named ’Peggy’ at edge of Saturn’s rings
2013 12 12
Nasa’s Cassini spacecraft has spotted an object located right at the edge of Saturn’s A ring that is confounding scientists. Its name? Peggy.
This strange something was spotted by accident on 15 April when Cassini’s cameras were aimed at a tiny moon named Prometheus that orbits just inside another of Saturn’s rings. A member of the mission’s imaging team, astronomer Carl ...
