    Kansas Legislator Proposes Bill to Outlaw Sustainability Education

    A bill has been introduced in the Kansas legislature this week that would prohibit the promotion of sustainability. Here is a link to the one-page bill: http://www.kslegislature.org/li/b2013_14/measures/documents/hb2366_00_0000.pdf. See report on Bloomberg News.

    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.

Crater

The constellation Crater is known as the Cup. Crater is a small constellation located between Hydra and Leo and next to Corvus. Crater is best seen sometime between March and June. You'll have to scan the sky closely because it is made mostly of dim stars.

The stories about Crater come from Greek myth. It is said that Corvus, the crow, was sent by Apollo to get some spring water. He took the cup to fill, and came across a fig that wasn't quite ripe. He waited for it to turn ripe, which made him late on his return. He brought a serpent with him and told Apollo that it attacked him and that was why he was late.

Of course, Apollo knew everything, so he was very angry that Corvus lied. He sent the crow, the cup and the serpent all into the sky. Another story says the cup is actually the sacred goblet used by the Olympian Gods. At one time, the constellation was seen as the young boy, Ganymede, who used to serve the gods nectar in the goblet. It was changed to represent the cup.
