The Center for Computational Astrophysics at the National Astronomical Observatory of Japan (NAOJ) has introduced the HPE Cray XD2000 system as a new supercomputer to replace the current dedicated ...

A Chinese-led international team has released the largest-ever cosmological simulation, named "HyperMillennium," offering ...

When black holes collide, the impact radiates into space like the sound of a bell in the form of gravitational waves. But after the waves, there comes a second reverberation—a murmur that physicists ...

A unique “moving van” is getting ready to haul a big load of supplies to space. But first comes precision, pre-flight practice.

NASA scientists have reached a breakthrough in computer modeling that allows them to simulate what gravitational waves from merging black holes look like. The three-dimensional simulations, the ...

Supermassive black holes at the centers of large galaxies grew mostly through the accretion of gas, with the occasional boost from mergers with other black holes. When you purchase through links on ...

A scientist from Tokyo Metropolitan University has shown that large gamma-ray-emitting bubbles around the center of the Milky Way were produced by fast, outward-blowing winds and an associated ...

Flux ropes (simulated, right) are structures made up of magnetic field lines wrapping around each other like a rope, that look similar to tornadoes on Earth. NOAA, Mojtaba Akhavan-Tafti and Chip ...
