Astronomers using the ESO Very Large Telescope, and the NASA/ESA Hubble Space Telescope, have made the most precise test yet of Einstein's general theory of relativity outside the Milky Way. The galaxy ESO 325-G004 distorts light from a galaxy behind it and creates an Einstein ring around its centre. By comparing the mass of ESO 325-G004 with the curvature of space around it, astronomers found that gravity on these astronomical length-scales behaves as predicted by general relativity.
Scientists at MIT and elsewhere have analyzed data from K2, the follow-up mission to NASA's Kepler Space Telescope, and have discovered a trove of possible exoplanets amid some 50,000 stars. In a paper that appears online today in The Astronomical Journal, the scientists report the discovery of nearly 80 new planetary candidates, including a particular standout: a likely planet that orbits the star HD 73344, which would be the brightest planet host ever discovered by the K2 mission.
A team of international astrophysicists may have found a solution to a problem that has perplexed scientists for more than 50 years: why are the stars in globular clusters made of material different to other stars found in the Milky Way?
An international team of astronomers have made the most precise test of gravity outside our own solar system.
Southern Texas and the western Gulf of Mexico is getting a soaking because of a low pressure system. The Global Precipitation Measurement mission or GPM core satellite passed over the western Gulf of Mexico and measured the rainfall from the system.
A storm of tiny dust particles has engulfed much of Mars over the last two weeks and prompted NASA's Opportunity rover to suspend science operations. But across the planet, NASA's Curiosity rover, which has been studying Martian soil at Gale Crater, is expected to remain largely unaffected by the dust. The Martian dust storm has grown in size and is now officially a 'planet-encircling' (or 'global') dust event.
Researchers at the University of Colorado Boulder have helped to find the last reservoir of ordinary matter hiding in the universe.
NASA Terra satellite captured an image of Tropical Depression Carlotta as it was making landfall in southwestern Mexico where it weakened into a remnant low pressure area.
Beneficial rainfall from hurricane Bud's remnants has spread into the US Desert Southwest after making landfall in western Mexico and moving north. NASA added up the rainfall using satellite data to provide a full picture of the rainfall.
Theoretical physicists from Maint and Stanford calculate the origin of a high-energy particle track captured by the IceCube Neutrino Observatory.
