James Webb Space Telescope Discovery Reveals a Dark Matter Anomaly Related to Ghostly ‘Einstein Ring’
A remnant of the early universe discovered last year by the James Webb Space Telescope has yielded a few astronomical surprises, including an Einstein ring and other properties that are now helping astrophysicists unveil new insights into the mysterious nature of dark matter.
The Mysterious Nature of Dark Matter May Finally be Solved
A new study proposes that Dark Matter, the elusive substance that makes up 85% of the universe, is likely made up of ultralight particles known as axions and not the Weakly Interacting Massive Particles, or WIMPs, favored by most current theories.
