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."

Hmm, Mercury Bar

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.

liquid core but little magnetism

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
