Stellar stream beyond Milky Way offers new tool to map dark matter
In the image above, a faint trail of stars can be seen stretching across the galaxy. These structures, known as globular cluster stellar streams, are coherent stellar structures that retain a record of their dynamical history and can provide unique insights into the evolution of galaxies and the nature of dark matter.
The science section covers breakthroughs in medicine, physics, biology, and technology. We surface discoveries that expand what humanity can do, from new treatments reaching clinical trials to engineering feats that seemed impossible a decade ago. Every link goes to the original publisher so you can read the full study or press release yourself.
