“This is the most sophisticated simulation to do this in the world right now.” ...

The temperature difference is not subtle. One side of the Milky Way’s outer halo runs noticeably hotter than the other, a ...

For the first time, scientists have reconstructed the full history of a galaxy outside the Milky Way using chemical clues. By ...

An astronomer at the University of Hawaiʻi at Hilo is using data from the Canada–France–Hawaiʻi Telescope (CFHT) on Maunakea ...

The smallest galaxies are challenging the conventional cosmological model. Scientists are studying these galaxies using sophisticated simulations.

A recent paper reveals we're almost certainly going to collide with a galaxy in the next couple billion years, but it's not the one we thought. Reading time 2 minutes For over a decade, researchers ...

New simulations of Milky Way-like galaxies reveal that the strange split between two chemically distinct groups of stars may arise from several very different evolutionary events. Bursts of star ...

Water may have first formed 100–200 million years after the Big Bang, according to a modeling paper published in Nature Astronomy. The authors suggest that the formation of water may have occurred in ...
