NASA says Dark Energy Survey helps us understand structure of the Universe

NASA - National Aeronautics and Space AdministrationPasadena, CA – What is our universe made of, and has its composition changed over time? Scientists have new insights about these fundamental questions, thanks to an international collaboration of more than 400 scientists called the Dark Energy Survey (DES).

Three scientists from NASA’s Jet Propulsion Laboratory in Pasadena, California, are part of this group that is helping to further our understanding of the structure of the universe.

The advances in astrophysics from DES are crucial to preparations for two upcoming space missions that will probe similar questions about the nature of the universe: ESA’s Euclid mission (which has significant NASA participation) and NASA’s Wide-Field Infrared Survey Telescope mission, both expected to launch in the 2020s.

The map covers about 1/30th of the entire sky and spans several billion light years in extent. Red regions have more dark matter than average, blue regions less dark matter.

APSU Students earn high marks for research at famed Fermilab

 

Austin Peay State University - APSUClarksville, TN – Mees Fix, an Austin Peay State University physics student, thought he might be in trouble. He was outside of Chicago, analyzing white dwarf stars at Fermilab – the U.S. Department of Energy’s national laboratory – when he noticed something strange. One of the stars was giving off way too much light energy.

“At first, I thought I broke something,” he said. “I figured I messed something up. I walked over to Dr. Smith and said, ‘check this out? What’s going on here?’” «Read the rest of this article»
