NASA Scientists Determine Europa Likely Spun on a Tilted Axis

NASA Scientists Find Evidence that Europa Likely Spun on a Tilted Axis at Some Point

By using data from NASA’s Galileo spacecraft to analyze the distinctive cracks lining the surface of Europa, NASA scientists determined that Europa likely rotated around a tilted axis at some point. This tilt could influence calculations of how much of Europa’s history is recorded in its frozen shell, how much heat is generated by tides […]

New Findings Challenge Assumptions about the Origins of Life

New Findings Challenge Assumptions about Origins of Life

New research from biochemists at the UNC School of Medicine offers an intriguing new view on how life began, challenging current assumptions about the origins of life. Chapel Hill, North Carolina — Before there was life on Earth, there were molecules. A primordial soup. At some point a few specialized molecules began replicating. This self-replication, […]
