Astronomy and astrophysics articles from across Nature Portfolio Astronomy and astrophysics are the study of objects and phenomena that are found beyond our solar system. This combines theoretical ...

The earliest and most distant supermassive black hole discovered thus far by JWST is CEERS 1019, which existed just 570 million years after the Big Bang and has a mass 9 million times that of the sun.

A team of scientists is proposing a bold alternative to the Big Bang theory, suggesting that our universe may have formed ...

Surprisingly, we found that even significantly higher dark energy densities would still be compatible with life, suggesting ...

The awe-inspiring distances of the cosmos are hard to visualise, so how can we be certain we are measuring them correctly?

The emerging geometry offers a rich phenomenology: a novel way to approach left-right symmetry on cosmological scale, a link of dark matter and dark energy to the dynamics of extra space, particles ...
