Some of the darkest objects in the universe are also among its brightest beacons, lighting up entire galaxies while their neighbors stay strangely subdued. The latest generation of supercomputer ...

Artist's conception of early starbursting galaxies. UC Davis astronomers collaborated on new simulations showing how bright galaxies could emerge early in the universe. Stars and galaxies are shown in ...

As planetary systems evolve, gravitational interactions between planets can fling some of them into eccentric elliptical orbits around the host star, or even out of the system altogether. Smaller ...

Advances in supercomputing have made solving a long‐standing astronomical conundrum possible: How can we explain the changes in the chemical composition at the surface of red giant stars as they ...

When high explosives are subjected to sudden shock waves, such as from an impact or detonation, tiny regions of intense heat—called hot spots—form at microstructural defects such as pores. These hot ...

Few scientific ideas have leapt from philosophy seminars to dinner-table debates as quickly as the claim that our universe might be an artificial construct. The simulation hypothesis promises a ...
