Instead of a single colossal collision, scientists have proposed that a string of impacts created miniature moons largely from terrestrial material. (sciencenews.org)
The researchers found that the release of terrestrial material trapped by icebergs creates a «halo effect» with significantly increased phytoplankton and krill populations out to a two - mile radius around the icebergs. (news.mongabay.com)
«This result is also significant because it shows that the Hall effect, a phenomenon first discovered in terrestrial materials and which is thought to help weaken a magnetic field through turbulence, can actually lead to an attractor state with a stable magnetic - field structure,» Gourgouliatos says.
