Using the biggest telescopes in the world, including the Very Large Telescope facility in Chile, the group has made detailed 3D maps of the galaxies, using the movement of their stars to "trace" the impression of the dark matter among them and weigh it very precisely.

Anything That Moves was a literary, journalistic, and topical magazine published in the United States from 1990 to 2002.[1] It was created as an expansion of the San FranciscoBay Area Bisexual Network (BABN) newsletter by BABN member, Karla Rossi, in collaboration with bisexual and bi-friendly editors, writers, and artists to become a full 64-page magazine with an international subscriber base.
