For decades, dark matter has been treated as the unseen framework around which galaxies take shape. Even the smallest ...

Scientists are shining a brighter light on dark matter thanks to a new high-resolution map, unveiling the invisible material that shapes everything we see. Using James Webb Space Telescope’s (JWST) ...

A new high-resolution map of dark matter, created using data from NASA’s James Webb Space Telescope, is offering more clues into the part the mysterious stuff plays in the formation of universe. The ...

Astronomers using NASA’s James Webb Space Telescope have produced a dark-matter map that doubles the sharpness of any previous effort, tracing the invisible mass that shapes galaxies across a patch of ...

Cosmic web Created using data from the JWST, this map shows how dark matter acts as the hidden framework on which visible galaxies are built. The overlaid contours mark regions of equal dark-matter ...

Scientists at Rutgers and collaborators have traced the invisible dark matter scaffolding of the universe using over 100,000 Lyman-alpha emitting galaxies. By studying how these galaxies clustered ...

A faint dwarf galaxy drifting 45 million light-years from Earth may have joined one of astronomy’s strangest clubs. It belongs to a tiny set of galaxies that seem to exist without dark matter.

Dark matter is some kind of substance that has gravity—it holds galaxies together—yet cannot be directly seen with any instrument yet created. We know it’s out there because of the effects it has on ...
