Greenland’s “double ridge” formations may have implications on a satellite millions of kilometres away. Jupiter’s moon, Europa, has an icy shell with double ridge formations that potentially have shallow pockets of water with evidence of life. Although it’s uncertain if the Europa and the Greenland ridges formed because of similar processes, the fact that Greenland’s double ridges were formed due to the refreezing, pressurisation, and fracture of shallow pockets of water make this a very real possibility, potentially making it easier to get samples of Europa’s water for examination.

‘Ghostly’ neutrinos provide new path to study protons
In groundbreaking research, an international collaboration of scientists from the University of Rochester have used a beam of neutrinos to measure the size and shape of the protons that make up the nuclei of atoms. This feat, once thought impossible, provides scientists with a new way of looking at the small components of an atom’s nucleus and opens up a wealth of new information about the structure of an atom’s nucleus and the dynamics of the forces that affect neutrino interactions. The researchers solved the challenge of harnessing neutrinos in large numbers by using a neutrino detector containing a target of both hydrogen and carbon atoms, and over nine years of data collection at Fermilab’s accelerator.
