Astronomers used James Webb Space Telescope data to determine the density of the universe's most mysterious "stuff." ...

Dark matter keeps getting blamed for the universe’s big patterns while staying stubbornly out of reach. You cannot see it, touch it, or capture it.

Researchers have used pulsar measurements to help uncover new information about the density of dark matter in our home galaxy. In a new study led by Rochester Institute of Technology Associate ...

Transformative discoveries in cosmology are unfolding at Princeton as researchers explore the universe’s large-scale structure, including galaxies, dark matter, and dark energy. Professor of ...

A study by Dartmouth researchers proposes a new theory about the origin of dark matter, the mysterious and invisible substance thought to give the universe its shape and structure. They say the ...

Dynamical friction. The panels depict sparse areas of the universe with dark colour and dense areas with light colour. The upper panels show the density around a galaxy if the galaxy's gravity bends ...

Scientists have found a new way to create a crystalline structure called a 'density wave' in an atomic gas. The findings can help us better understand the behavior of quantum matter, one of the most ...
