(A) Dark matter distribution in our neighborhood in the Universe, the so-called Local Group of galaxies. The two large dark matter halos correspond to those of the Milky Way and Andromeda galaxy; (B) ...

Using the James Webb Space Telescope, scientists spotted thin and thick disks in galaxies as far back as 10 billion years ago—something never seen before. These observations reveal that galaxies first ...

Satellite galaxies are low-mass companions bound to more massive host galaxies within a common dark matter halo. In the Local Group—dominated by the Milky Way and Andromeda—these satellites exhibit a ...

An international team led by UNIGE shows that red and dead galaxies can be found only 700 million years after the Big Bang, indicating that galaxies stop forming stars earlier than predicted by models ...

One of the goals of the Webb Space Telescope was imaging the earliest galaxies, giving us a new window into how our Universe evolved between the dense, hot material from the Big Bang and its star- and ...
