The Milky Way's system of small, orbiting satellite galaxies is quite unusual, a new 12-year study of other galaxies in the local universe has found. The Satellites Around Galactic Analogs (SAGA) ...

A long-term survey of small, “satellite” galaxies that orbit larger galaxies across the universe offers new insights into our own galaxy, the Milky Way. Since 2012, the Satellites Around Galactic ...

In space, the gravitational pull of massive objects is irresistible to smaller ones. Moons are locked in orbit around planets. Planets, asteroids and comets orbit more massive stars, and stars collect ...

The dark matter distribution of a Milky Way mass halo in a Lambda-cold dark matter (LCDM) cosmological simulation. This is the highest resolution simulation of a MW-mass dark matter halo ever ...

A team of astronomers has discovered the faintest dwarf satellite galaxy of the Milky Way. Virgo 1, discovered using the Subaru Telescope in Hawaii, has an absolute magnitude of -0.8 in the optical ...

One of the new high-resolution simulations of the dark matter enveloping the Milky Way and its neighbour, the Andromeda galaxy. The new study shows that earlier, failed attempts to find counterparts ...

Crater 2, located approximately 380,000 light years from Earth, is one of the largest satellite galaxies of the Milky Way. Extremely cold and with slow-moving stars, Crater 2 has low surface ...
