Our Milky Way Galaxy is orbited by more than 50 companion galaxies. According to new research led by University of California, Riverside astronomers, several of these tiny galaxies were captured from an orbit around the Large Magellanic Cloud (LMC), a small galaxy located 160,000 light-years away. “Our results are an important confirmation of our cosmological […]

Lunar orbiters such as India’s Chandrayaan-1 spacecraft and NASA’s Lunar Reconnaissance Orbiter (LRO) recently detected water icy on the floor of some of the south polar craters, but no one is sure exactly when or how that ice got there. A new study by researchers from Brown University and NASA’s Goddard Space Flight Center suggests […]

Humans have a threshold limit for instantly processing one to four elements accurately; and it seems that our species is not alone, says a team of scientists from France and Australia. “Guppies, angelfish and even honeybees are capable of distinguishing between quantities of three and four, although the trusty insects come unstuck at finer differences; […]

Using data gathered by the NASA/ESA Hubble Space Telescope, astronomers have calculated the mass inflow and outflow rates of cool ionized gas around our Milky Way Galaxy and found an unexpected and so-far unexplained surplus of inflowing gas. Prior to this new study, astronomers knew that the galactic gas reserves are replenished by inflow and […]
