The whirlpool galaxy Messier 51 (M51) is seen from a distance of approximately 30 million light years. This galaxy appears almost face-on and displays a beautiful system of spiral arms.
The discovery of a split-second burst of radio waves by scientists using the Arecibo radio telescope in Puerto Rico provides important new evidence of mysterious pulses that appear to come from deep in outer space.
The discovery of three closely orbiting supermassive black holes in a galaxy more than four billion light years away could help astronomers in the search for gravitational waves: the 'ripples in spacetime' predicted by Einstein.
Powerful radio signals that Jupiter generates could be used to help researchers scan its giant moons for oceans that could be home to extraterrestrial life, according to a recent study submitted to the journal Icarus.
It may look like just dots on a page, but an image of distant galaxies taken last week represents a huge step forward for CSIRO's Australia SKA Pathfinder (ASKAP) radio telescope in Western Australia.
Astronomers using the Karl G. Jansky Very Large Array (VLA) and the Chandra X-Ray Observatory have produced a spectacular image revealing new details of violent collisions involving at least four clusters of galaxies. Combined ...
Astronomers harness the galaxy's biggest telescope to make most precise measurement of spinning star
(Phys.org) —An international team of astronomers has made a measurement of a distant neutron star that is one million times more precise than the previous world's best.
When the SpaceX-3 cargo resupply mission launched to the International Space Station April 18, an experiment designed by NASA's Jet Propulsion Laboratory in Pasadena, Calif., was among the cargo headed to space.
As the effort to find Malaysian Airlines flight MH370 moves inexorably towards the recovery stage, the challenge of finding the plane's flight recorder (called the "black box" even though it's actually bright orange) on the ...
