Scientists have simulated the formation of our entire Universe with a large supercomputer. A gigantic catalogue of about 25 billion virtual galaxies has been generated from 2 trillion digital particles.
For the third time, researchers have detected gravitational waves predicted by Albert Einstein 100 years ago. A pair of black holes with 31 and 19 solar masses had merged into a single one with a mass about 49 times that of our Sun.
Astronomers have put a basic principle of black holes to the test, showing that matter completely vanishes when pulled in. Their results constitute another successful test for Albert Einstein's General Theory of Relativity.
Thousands of processors, terabytes of data, and months of computing time have helped a group of researchers create some of the largest and highest resolution simulations ever made of galaxies like our Milky Way.
Using 3D numerical models, an international team has discovered a proxy that could be used to forecast an eruptive event. The proxy is associated with magnetic helicity, which reflects the extent of twist and entanglement of the magnetic field.
The combined power of three space observatories, including NASA's Hubble Space Telescope, has helped astronomers uncover a moon orbiting the third largest dwarf planet, catalogued as 2007 OR10. The pair resides in the frigid outskirts of our solar system called the Kuiper Belt, a realm of icy debris left over from our solar system's formation 4.6 billion years ago.
The surfaces of Earth, Mars, and Titan, Saturn's largest moon, have all been scoured by rivers. Yet despite this similarity and the amazingly Earth-like landscapes of Titan complete with valleys, lakes, and mountains, researchers report new evidence that the origins of the topography there and on Mars are different from on Earth.
