Galaxies lack dark matter after collision
Astronomers have discovered two galaxies in the Fornax cluster, known as FCC 224 and FCC 240, which are devoid of dark matter. The stars in these galaxies are moving slowly as a result of a violent collision that occurred 10 billion years ago. The team explained that the collision caused the dark matter to separate, while the stars and gases remained united, forming these two new galaxies.
