Powerful simulations reveal how the first stars changed the universe
来源: All Top News -- ScienceDaily · 发布于
Ultra-detailed simulations are showing how the first stars lit up the dark Universe and seeded space with elements such as carbon, oxygen, and iron. The MEGATRON project could bridge JWST observations of the earliest galaxies with chemical clues preserved in ancient stars today.

Black hole jets may decide the fate of entire galaxies
Powerful jets from supermassive black holes can disturb star-forming gas far beyond a galaxy’s visible edge, leaving a glowing trail hundreds of thousands of light-years long. By keeping this gas hot and preventing it from falling inward, the jets may help determine whether a gal
