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.

Milky Way may have begun as thousands of galaxies, new simulations suggest
In the early days of the universe, our home looked very different from how it does today. Back then, the region in our universe that would eventually become our Milky Way neighborhood was a collection of thousands of smaller galaxies—some pumping out tons of new stars, others fil

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

This suitcase-sized spacecraft could hear the universe before stars existed
CosmoCube will use the far side of the Moon as a shield from Earth’s radio noise to search for a faint signal from the universe before the first stars existed. The suitcase-sized satellite could reveal how the cosmic dark ages ended and how dark matter helped build the first gala
