They discovered that dark matter accounted for roughly 60% of each galaxy's total mass by examining their rotation curves.

Created as a tribute to dark matter pioneer Vera Rubin, the image was created with the aid of a vast array of telescopes.

To dark matter and dark energy, add dark galaxies — collections of stars so sparse and faint that they are all but invisible. An artist’s depiction of hydrogen gas observed in the galaxy J0613 ...

Dark matter in dwarf galaxy tracked using ... the team reduced the amount of assumptions applied in previous studies and considered characteristics specific to the galaxy -- such as its rotation, ...

How the pioneering scientist, and namesake of an enormous new telescope, forced astronomers to rethink the universe.

Observations of galaxy rotation curves: Evidence for Dark Matter in Spiral Galaxies Dark matter’s role in explaining rotation curves: The Rotation Curves of Spiral Galaxies QI theorists contend that ...

Dark dwarfs, stars composed of dark matter, may be the optimal objects in which to finally discover physical dark matter in the real world.

Scientists discovered a galaxy, AGC 114905, that may not have dark matter, and they are not quite sure how. It could challenge ideas of how galaxies are formed.

By studying the rotation curves of each galaxy (Figure 2), they found dark matter made up about 60 per cent of its total mass. Velocity changes with radius in the galaxy are captured by blue-shifted ...

Dark matter is invisible, non-baryonic matter hypothesized to explain phenomena including gravitational lensing and galactic rotation curves. Dark energy is thought to permeate the Universe and ...
