As the moon reoriented, it left behind a trail of water ice, effectively "painting out" the path that the poles took with time.
Led by scientist Matt Siegler, the team noted in their report that ice boils off into space when exposed to direct sunlight.
The eclipse is projected to last for 4 hours and 15 minutes on Wednesday morning, during which time a minimum of part of the southern part of the Moon will be have moved with the pale penumbra. However on Tuesday night, Jupiter will be very bright and will join a waxing moon for a picturesque celestial view.
Did you see Jupiter and the moon together in the night sky? "It would be as if Earth's axis relocated from Antarctica to Australia". Instead, the "Man in the Moon" nodded up and down, because of heating and volcanic eruptions on the Earth-facing side of the moon. Scientists, including one from Alabama, say "yes" in a paper published today in the journal Nature.

Today's news follows yesterday's announcement that Google would be opening 12 more regions of data centers around the world. The expansion will boost the speed of Google's Cloud Platform services in certain regions.

On Earth, polar wander is believed to have happened due to movement of the continental plates. Their work points to the Procellarum KREEP Terrane (PKT) region on the lunar nearside, which was volcanically active long ago. The moon's change in mass was internal-the shift of a large, single mantle "plume". When the moon formed, numerous body's radioactive elements ended up in the Procellarum. Thanks to Malaysian-based observer Sharin Ahmad (@shahgazer on Twitter) for pointing this out to us. Researchers claim Earth's satellite shifted approximately six degrees to its current axis, or roughly 201 kilometers (125 miles). It's caused when the moon passes through Earth's outer shadow - the penumbra. One of Prospector's instruments recorded the speeds of neutrons streaming from the lunar surface.
In the case of the moon, any water coming from an asteroid would have eventually made its way to the shadowed areas to be permanently trapped. The spacecraft found regions that lack high-speed neutrons, which presumably have been slowed by hydrogen atoms from water molecules.
"The maps show four key features", said Siegler and his colleagues. More recent water wouldn't show such an antipodal pattern. But a new study suggests that the moon may have had a much more radical change back in its ancient history: The moon may once have spun on a different axis.
