Mercury May Have Molten Hot Magma at its Core
mattatwork writes "According to ScienceDaily, NASA has come to the conclusion that the planet Mercury may have a molten core after all, based on high-precision planetary radar readings. You may (or may not) remember the Mariner 10 probe making 3 passes by Mercury between March 29th, 1974, September 21st 1974 and March 16, 1975."
Buy the new Mercury Bar, with a molten caramel core!
No more hard frozen Mars Bars. Let the chocolatey warmth flow through you.
"Magma: Molten rock beneath the surface of the earth." http://www.google.com/search?q=define%3A+magma "Molten hot magma" If it's magma, it's molten, molten rock is pretty much definately hot.
it is quite odd that mercury has a liquid metal core but a very weak magnetic field- planetary magnetic fields form when currents flow through a liquid core- the rotating core sustains the field as on earth, the sun and jupiter but mercury's is very weak- apparently it isn't rotating much
Sigs are too short to say anything truly profound so read the above post instead.
This is compared with the recent discovery of mud-like sludge in the core of Uranus.
You know, Scott. I've been a frickin' evil doctor for 30 frickin' years, OK? Cut me some "frickin'" slack. You forget Scott. We're in a volcano. We're surrounded by liquid hot magma.
McDonalds jokes are a medium rarely well done.
Support the mob or mysteriously disappear.
Shouldn't the title be, "Mercury May Mask a Molten Middle"?
Don't listen to this guy. Mercury is not tidally locked with the sun, but rotates very slowly at about 3 rotations for every 2 revolutions around the sun. And even more, an ocean does not act as any sort of a buffer against gravitational forces from the sun. There's just not a significant enough amount of water even on Earth to do so.
