Scientists have discovered a giant cosmic filament where galaxies spin in sync with the structure that holds them together.

After the Big Bang came the earliest galaxies. Due to the expansion of the universe, these galaxies are receding away from us. This causes their emissions to be redshifted (shifted towards longer ...

From our vantage point inside it, the Milky Way can feel infinite, a hazy river of light that wraps around the sky. Yet when ...

A newly identified string of galaxies, stretched across tens of millions of light years and slowly turning in space, is forcing astronomers to rethink how structure and motion emerge on the grandest ...

One researcher’s analysis of Webb Space Telescope images could indicate that we’re all stuck in a black hole, according to research published in the Monthly Notices of the Royal Astronomical Society. ...

Early 20th-century astronomical observations revealed unexpectedly high rotational speeds in the outer regions of spiral galaxies, prompting the hypothesis of dark matter by Fritz Zwicky in 1933. Vera ...

Galactic Astronomy encompasses the study of the structure, dynamics and evolution of galaxies – ranging from our own Milky Way to distant systems – through multifrequency observations and ...

Although dark matter is a central part of the standard cosmological model, it’s not without its issues. There continue to be nagging mysteries about the stuff, not the least of which is the fact that ...
