    Kansas Legislator Proposes Bill to Outlaw Sustainability Education

    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.

Draco the Dragon

Draco the dragon is famous throughout mythology. This great beast was especially present in greek myth. One of the more popular stories involves Heracles and the twelve labors. Gaia gave Hera a golden apple tree when she married Zeus. Hera put the tree in the garden to be guarded by the Hesperides and a dragon called Ladon.

Heracles asks Atlas to gather the apples while he and Athena held up the sky. Atlas, thinking he could trick Heracles into holding the sky forever, gladly accepted the mission. When he returned with the apples, Heracles slipped the sky back on Atlas' shoulders.

Yet another story is set during the Titan war with Zeus. Athena was attacked by a dragon. She flung it into the air, wrapping it around the pole. To this day, the dragon remains in the night sky.

The constellation, Draco, can be found revolving around the celestial North Pole. This type of constellation is said to be circumpolar.
