    Earth's Center Is 1,000 Degrees Hotter Than Previously Thought, Synchrotron X-Ray Experiment Shows

    Scientists have determined the temperature near the Earth’s center to be 6000 degrees Celsius, 1000 degrees hotter than in a previous experiment run 20 years ago. These measurements confirm geophysical models that the temperature difference between the solid core and the mantle above, must be at least 1500 degrees to explain why the Earth has a magnetic field. For more information about this study, see the press release from the European Synchrotron Radiation Facility.

    Ocean Volcanic Rocks Contain Samples of Recycled Crust

    Scientists have long believed that lava erupted from certain oceanic volcanoes contains materials from the early Earth’s crust. But decisive evidence for this phenomenon has proven elusive. New research from a team including Carnegie’s Erik Hauri demonstrates that oceanic volcanic rocks contain samples of recycled crust dating back to the Archean era 2.5 billion years ago. Their work is published in Nature. Oceanic crust sinks into the Earth’s mantle at so-called subduction zones, where two plates come together. Much of what happens to the crust during this journey is unknown. Model-dependent studies for how long subducted material can exist in the mantle are uncertain and evidence of very old crust returning to Earth’s surface via upwellings of magma has not been found until now. For more information about these results, see the press release from the Carnegie Institution.

Maui

Maui was a hero of Polynesian mythology. For Maui and his mother the days were too short. Maui wanted his mother to have more daylight to make bark cloth. He thought that if the Sun were moving slower across the sky, there would be more hours of light in one day.

So, Maui cut off the sacred tresses of his wife, Hina, to make a rope that would not burn in the Sun. With his rope he caught the Sun as it was rising and beat it with the magic jawbone of his grandmother.

The Sun was so weak after the beating that it could not run but only creep along its course. In this way, sunlight lasted longer, and it was possible to work more during the day.
