A new study conducted by scientists at the Southwest Research Institute in Boulder, Colorado, has this week posited that Saturn’s rings are the remnants of a massive moon that once orbited Earth’s distant neighbour.
According to study author and astronomer Robin Canup, the moon plunged into Saturn around 4.5 billion years ago due to a giant ring of hydrogen gas responsible for creating rocky satellites but also for dragging larger moons out of orbit.
The scientific theory centres on the predominantly icy composition of Saturn’s rings, The Tech Herald reports. (more…)
ANN ARBOR, Mich.— One-fifth of the world’s vertebrate species are threatened with extinction, but the situation would be worse if not for current global conservation efforts, a new study finds.
University of Michigan biologist Ronald Nussbaum is one of 174 researchers from 115 institutions and 38 countries who authored the study published this week in Science Express.
The study used data for 25,000 species from the International Union for Conservation of Nature’s Red List of Threatened Species to investigate the status of the world’s vertebrates (mammals, birds, amphibians, reptiles and fishes) and how this status has changed over time. The results show that, on average, 50 species of mammal, bird and amphibian move closer to extinction each year due to the impacts of agricultural expansion, logging, over-exploitation, and invasive alien species.
