Results from the first data release of the Dark Energy Survey include eleven new stellar streams in the Milky Way galaxy.
Spacetime ripples from the neutron star smash-up usher in the age of multi-messenger astronomy.
On June 1, U.S. and European physicists published the latest results in their quest for gravitational waves — tiny ripples in spacetime, generated by energetic events like the collision and merger of distant black holes. Meanwhile, a new gravitational wave observatory is under construction in Japan. Sky & Telescope Contributing Editor Govert Schilling visited the KAGRA detector in 2016.
Ground- and space-based observations have now shed intriguing new light on a mysterious radio source more than 3 billion light-years away.
Traveling through space can be a bumpy ride! Join Govert Schilling on a scenic road trip across southern Africa filled with craters and meteorites.
Hubble has spotted more than 100 small, faint galaxies in the young universe, common as dust bunnies but previously out of reach of even the best telescopes.
Astronomers analyzing a new sky survey have found that the distribution of dark matter in the modern universe is smoother than predicted from observations of a far younger universe.
It's not easy to get to the Murchison Radio Observatory in Western Australia. Being in one of the most remote regions of the country means there's hardly any radio interference that might otherwise compromise the astronomical observations. It's one of the most radio-quiet zones on the planet.
