A new supercomputer simulation helps explain the existence of puzzling supermassive black holes observed in the early universe. The simulation is based on a computer code used to understand the coupling of radiation and certain materials. “Supermassive black holes have a speed limit that governs how fast and how large they can grow,” said Joseph Smidt of the Theoretical Design Division at Los Alam...

Humanity may soon generate more data than hard drives or magnetic tape can handle, a problem that has scientists turning to nature’s age-old solution for information-storage—DNA. In a new study in Science, a pair of researchers at Columbia University and the New York Genome Center (NYGC) show that an algorithm designed for streaming video on a cellphone can unlock DNA’s nearly full storage potenti...

Through a supercomputer-simulated study, astronomers at Lund University in Sweden show that it is highly likely that the so-called Planet 9 is an exoplanet. This would make it the first exoplanet to be discovered inside our own solar system. The theory is that our sun, in its youth some 4.5 billion years ago, stole Planet 9 from its original star. Listen to Alexander Mustill as he explains! An exo...

HITS astrophysicists use new methods to simulate the common-envelope phase of binary stars, discovering dynamic irregularities that may help to explain how supernovae evolve. The results are published in The Astrophysical Journal Letters. The simulation video made by Sebastian Ohlmann visualizes the evolution of the density during a time span of 105 days. density development process in a 105 days...

NASA GSFC solar scientist Holly Gilbert explains a computer model of the sun’s magnetic field. Grasping what drives that magnetic system is crucial for understanding the nature of space throughout the solar system: The sun's invisible magnetic field is responsible for everything from the solar explosions that cause space weather on Earth – such as auroras – to the interplanetary magnetic field and...

Ever since Hurricane Ike devastated Texas in 2008, researchers at the Institute for Computational Engineering and Sciences at the University of Texas at Austin have been studying computational models and simulations of hurricanes like Ike in order to predict the effects of future storms and better prepare the coastal regions of Texas, such as the Galveston Bay region, for its effects. Environmenta...
