Researchers using the James Webb Space Telescope spotted huge stars leaking nitrogen in an early galaxy, hinting that such ...

The first generation of stars that were born in the universe are a mystery. We can estimate when they existed and even how ...

"A bit like dinosaurs on Earth — they were enormous and primitive. And they had short lives, living for just a quarter of a ...

JWST uncovers evidence of ancient “monster stars” whose extreme chemistry may explain the origins of early supermassive black ...

Most of the universe is made up of dark matter and dark energy. The majority of everything else is dispersed throughout space ...

The discovery of strange, ultra-red objects—especially the extreme case known as The Cliff—has pushed astronomers to propose an entirely new type of cosmic structure: black hole stars. These exotic ...

Stars are the original nuclear fusion reactors. As it evolves, a star continuously fuses hydrogen, helium, and—if it becomes big enough—heavier elements, releasing the energy created into space as ...

In a glimpse of the early universe, astronomers have observed a galaxy as it appeared just 800 million years after the Big ...

Not all stars are created equally. Astronomers believe that the first stars to form after the Big Bang were mostly made of only hydrogen and helium with trace amounts of lithium, as the heavier ...

In the dense environment of the early universe, dark matter particles would collide with, and annihilate, each other, ...

In the end, the Universe becomes a place where gravity and quantum physics slowly turn all mass into faint streams of particles.
