This new discovery of a galaxy that contains little or NO Dark Matter is so huge it puts my blog about yesterday's "Return to The Moon" conference in Washington, D.C. on hold.
Astronomers just announced yesterday that using an array of commercial 400mm telephoto lenses called Dragonfly they have found a galaxy called NGC 1052-DF2 that is the size of the Milky Way Galaxy (MWG), contains less than 0.5% of the stars in the MWG, and has little or no Dark Matter which is found in every other galaxy to date.
This galaxy is so sparse that when the Hubble Space Telescope (HST) photographed it distant background galaxies could be seen through it!
This discovery will force astronomers to rethink how galaxies form as NGC 1052-DF2 shows that DM isn't present in all galaxies as they once thought. It also shows that DM is real and not some type of gravitational interaction that allows galaxies to form mimicking DM. If that was true then NGC 1052-DF2 would have to be like very other galaxy.
As I have always said, "Stay tuned as the Universe always surprises us."
