Recent studies using the Hubble Telescope have revealed that the Milky Way merged with other galaxies in the past, which significantly influenced its structure and evolution.

Astronomers have discovered an unusual galaxy, CDG-2, which is composed almost entirely of dark matter and contains virtually no stars. This discovery is significant for studying the nature of dark galaxies and the mysteries of dark matter.

Recent studies show that low-mass black holes cannot account for all the dark matter in the Universe. However, debates about the nature of dark matter continue, and new discoveries may change scientists' perspectives.
