Weak starlight in Hubble images reveals the distribution of dark matter – ScienceDaily

Astronomers using NASA / ESA Hubble Space Telescope data have used a revolutionary dark matter detection method in galaxy clusters. The method allows astronomers to "see" the distribution of dark matter more accurately than any other method used so far, and could potentially be used to explore the ultimate nature of dark matter. The findings were published in the journal …

For a hundred years, it has consistently predicted all sorts of crazy phenomena that scientists later observed in outer space. An international team now announces that a 26-year observational campaign has re-confirmed the theory. Astronomers using …
