- Scientists think dark matter might come in two forms
Scientists propose dark matter may consist of two interacting particle types, addressing discrepancies in gamma ray signals observed in the Milky Way versus dwarf galaxies. The theory challenges existing dark matter models by suggesting multiple particle types rather than a single particle.
- Dozens of hidden star streams found in the outskirts of our Milky Way galaxy
Astronomers have discovered dozens of hidden star streams in the Milky Way's outskirts, revealing remnants of dwarf galaxies and star clusters. These streams highlight gravitational interactions between stars, dark matter, and the galaxy itself.
