Essentially, galaxy clustering constraints on σ 8 probe the growth of structure from the early universe (where we have precise measurements thanks to the cosmic microwave background) to late times.

The most precise 3-D map of our Milky Way galaxy has been revealed by astronomers. The 3-D Milky Way map was created using data from the European Space Agency’s Gaia space probe that’s been ...

But researchers love a challenge, and after years of toil a Polish team has released the most complete map of our galaxy to date. They didn’t try to plot all its hundreds of billions of stars.

But to top it off, its one-billion-pixel camera will also chart each star’s distance and two-dimensional velocity, providing a five-dimensional map of the Milky Way Galaxy. (Three-dimensional ...

The best data for looking at the galaxy distribution comes from the Sloan Digital Sky Survey (SDSS), which is constructing the largest 3D map of the universe. When completed, it will map the ...

A stunning new map of the magnetic fields at the Milky Way's center charts never-before-seen features, and raises new questions about how our galaxy's central engine works. When you purchase ...

Turbulence is ubiquitous — from coffee cups to ocean waves and bumpy flights. And this powerful state isn’t limited to Earth; its influence extends throughout the galaxy and universe.  Despite ...

This water map, with unprecedented resolution, is the first ever to be obtained for such a remote galaxy. The map can help scientists to understand the physical processes taking place within J1135 ...

blue-tinged image showing the neutrinos' sources all across our galaxy. The map showed that the neutrinos were being overwhelmingly produced in regions with previously detected high gamma-ray ...
