Just a few hundred million years after the Big Bang, the universe was a dark and simple place. There were no galaxies like ...

Dark matter halos are everywhere in the universe, yet no telescope can see them. These vast, invisible structures surround ...

Advanced cosmological models suggest up to eight starless dark galaxies lie hidden in the immediate vicinity of the Milky Way ...

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 ...

The notion that our universe might be a giant simulation has intrigued scientists and philosophers for decades. Recent advancements in technology and theoretical physics have reignited this debate, ...

One of the key missions of the NASA/ESA/CSA James Webb Space Telescope is to probe the early universe. Now, the unmatched resolution and sensitivity of Webb's NIRCam instrument have revealed, for the ...

The world's most powerful supercomputer dedicated to astronomy simulations was recently used to simulate the formation of a cluster of baby stars. Astronomers at the National Astronomical Observatory ...

For the first time, a group of cosmologists say they’ve created virtual galaxies inside their computers without any dark matter. Critics of dark matter see it as a win for a controversial model of how ...

Add Yahoo as a preferred source to see more of our stories on Google. Astronomy lessons and activities. The number of astronomy lessons and activities is nearly as infinite as the cosmos themselves!

Parallel N-body simulations form the computational backbone for modelling the dynamical evolution of astrophysical systems, from planetary rings and protoplanetary discs to galaxy clusters and ...

Cosmological simulations of dark matter halos form the backbone of our understanding of large-scale structure in the Universe. By numerically evolving millions to billions of particles under gravity, ...
