Space Station to Host New Cosmic Ray Telescope

UChicago’s Angela Olinto leads U.S. collaboration on international project

The National Aeronautics and Space Administration has awarded $4.4 million to a collaboration of scientists at five United States universities and NASA’s Marshall Space Flight Center to help build a telescope for deployment on the International Space Station in 2017.

The U.S. collaboration is part of a 13-nation effort to build the 2.5-meter ultraviolet telescope, called the Extreme Universe Space Observatory. UChicago Prof. Angela Olinto leads the U.S. collaboration. The telescope will search for the mysterious source of the most energetic particles in the universe, called ultra high-energy cosmic rays, from the ISS’s Japanese Experiment Module. The source of these cosmic rays has remained one of the great mysteries of science since physicist John Linsley discovered them more than 50 years ago. These cosmic rays consist of protons and other subatomic scraps of matter that fly through the universe at almost light speed. (more…)

Confidence in Climate Data: Using 3 Million-Year-Old Records

How do we understand what’s happening today by looking back millions of years?

Scientists are looking at what climate conditions were like 3.3 to 3 million years ago, during a geologic period known as the Pliocene, and they are confident in the accuracy of their data.

The Pliocene is the most recent period of sustained global warmth similar to what is projected for the 21st century. Climate during this time period offers one of the closest analogs to estimate future climate conditions. (more…)
