    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.

The COSPIN instrument image page

This is a photograph of the Dual Anisotropy Telescopes (ATs). The ATs are outlined with a yellow line. The LET (Low Energy Telescope) is also shown outlined with a green circle. The cover shown in this picture covering the LET was opened after launch. The bottom third of the box actually contains the data processing unit (DPU). The DPU collects measurements from all of the telescopes on COSPIN and sends them to the spacecraft data system.

This is a photograph of the High Energy Telescope (HET) and the High Flux Telescope (HFT). The HFT is the small fan-shaped object on top of the box (outlined in blue). The HET is outlined in purple. You can see that the HFT has a bronze strip covering it and the HET has a large, circular gold cover on it. Both of these covers were opened after launch.

This is a photograph of the Kiel Electron Telescope (KET).
