This Nov. 16, 2017 image made with the Hubble Space Telescope shows the diffuse galaxy NGC 1052-DF2, lighter area in centre. Several other galaxies can be seen through it. The unusual galaxy's stars are speeding around with no apparent influence from dark matter, according to a study published on Wednesday, March 28, 2018 in the journal Nature.Pieter van Dokkum / AP
WASHINGTON — Astronomers have found a distant galaxy where there is no dark matter, the invisible stuff that makes up more than a quarter of the universe.
Scientists only know dark matter exists because they can observe how it pulls and pushes things they can see, like stars. It’s supposed to be everywhere.
But Yale University astronomer Pieter van Dokkum and colleagues spied an old galaxy with relatively few stars where what you see truly is what you get. They say the stars in the galaxy are travelling at a speed that suggests no influence from dark matter.
This 2016 photo provided by Pieter van Dokkum shows the “Dragonfly” telescope in New Mexico. Using the assembly, van Dokkum and colleagues found a large, thin galaxy called NGC1052–DF2 in the northern constellation Cetus. ItÂ’s as big as the Milky Way but with only one percent of its stars. Then they used larger telescopes on Hawaii and eventually the Hubble Space Telescope to study the galaxy. (Pieter van Dokkum via AP)
The study is in Wednesday’s journal Nature.
Scientists have no good explanation for how this could be, but outsiders said the researchers calculations appear to be sound.

Maybe, the police up there shot all of the Black Matter.
