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) ...

Astronomers know that mergers play a huge role in galaxy growth. Right now, the Milky Way is slowly consuming the Large and ...

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 ...

Our search for exoplanets is focused on Milky Way stars. It's been successful, with more than 6,000 detected so far.

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 ...

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 ...

UNDATED (WKRC) - Scientists captured the first-ever close-up picture of a star outside of the Milky Way galaxy, ushering in a new era of cosmic study. The European Southern Observatory (ESO) released ...

A research team led by physicists at the University of California, Riverside, reports tiny satellite galaxies of the Milky Way can be used to test fundamental properties of “dark matter” — nonluminous ...

The Milky Way could have many more satellite galaxies than scientists have previously been able to predict or observe, according to new research. Cosmologists at Durham University used a new technique ...
