The stars move quickly because they are very close to each other, separated by only about one-fourth the distance from the Earth to the Moon. As a result, they share strong gravitational forces. They were once farther apart but have spiraled closer together over time. Billions of years from now, they will crash together and merge. [...more]
The results show mergers of two dense stellar remnants are the likely cause of many of the supernovae that have been used to measure the accelerated expansion of the universe. [...more]
This fossil represents a new genus and species of extinct aneuretopsychid, Jeholopsyche liaoningensis, recently described in a paper in the journal ZooKeys by Conrad Labandeira of the Smithsonian’s National Museum of Natural History, and Dong Ren and ChungKun Shih of the College of Life Sciences, Capital Normal University, Beijing. The aneuretopsychidae are a family of long-proboscid insects that lived in Asia from the Late Jurassic to Early Cretaceous. The paper documents the first formal record of fossil Aneuretopsychidae in China. The new fossils reveal previously unknown and detailed structure of the mouthparts, antennae, head, thorax, legs and abdomen of this distinctive insect lineage.
