A new international study involving ANU has found a plane of dwarf galaxies orbiting around Centaurus A in a discovery that challenges a popular theory about how dwarf galaxies are spread around the Universe.
CU Boulder researchers have discovered a mechanism that explains the persistence of asymmetrical stellar clusters surrounding supermassive black holes in some galaxies and suggests that during post-galactic merger periods, orbiting stars could be flung into the black hole and destroyed at a rate of one per year.
Some of the smallest creatures on the planet — zooplankton — make the most widespread vertical migration of biomass on Earth. Billions of these animals move deeper into the ocean and away from the light during the day to avoid predators, and migrate up again in the dark of night to feed.
A new study finds polar bears in the wild have higher metabolic rates than previously thought, and as climate change alters their environment a growing number of bears are unable to catch enough prey to meet their energy needs.
