Astronomers find galaxy Y1, a young star-forming region, revealing extreme heat just 600 million years after the Big Bang.

A recent study provides answers to three seemingly disparate yet pressing cosmic dawn puzzles. Specifically, the authors show ...

Immediately after the Big Bang, which occurred around 13.8 billion years ago, the universe was dominated by unimaginably high temperatures and densities. However, after just a few seconds, it had ...

All galaxies (including our own) are thought to exist inside a giant cosmological structure called a dark matter halo - a cloud-like phenomenon made up of invisible matter that forms a scaffold to the ...

A paper links dark stars to Webb telescope puzzles involving bright sources, dust-free galaxies, and early black holes.

Astronomers have used the James Webb Space Telescope to peer inside the heart of spiral galaxies, where young stars carve out glowing paths. The space observatory, named after a North Carolina native, ...

Gas cloud collisions during galaxy mergers compress interstellar material, triggering new star formation, as observed in interacting systems studied by NASA and reported by Universe Today.

Theorists have long wondered how massive stars–up to 120 times the mass of the Sun–can form without blowing away the clouds of gas and dust that feed their growth. But the problem turns out to be less ...
