This effect has allowed Jauzac and her colleagues to calculate the distribution of visible and dark matter in the cluster and produce a highly constrained map of its mass.

NASA's James Webb Space Telescope recently zeroed in on the Bullet Cluster—delivering highly detailed images that show a greater abundance of extremely faint and distant galaxies than ever ...

By observing these clusters, astronomers will map the dark matter distributions and look for more conclusive evidence of early cluster formation, and possibly early dark energy.

The new maps show that the Milky Way galaxy, along with the Virgo cluster and some 100,000 other galaxies, is gravitationally sailing in the same gigantic cosmic pool, named Laniakea.

vcluster is the first virtual cluster solution that passes 100% of Kubernetes conformance tests and becomes certified Kubernetes distribution.

(PhysOrg.com) -- Two teams of astronomers have used data from NASA's Chandra X-ray Observatory and other telescopes to map the distribution of dark matter in a galaxy cluster known as Abell 383 ...

Astronomers have mapped the mass within a galaxy cluster more precisely than ever before. Created using observations from Hubble's Frontier Fields observing program, the map shows the amount and ...
