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 ...

A supermassive black hole residing within the Large Magellanic Cloud (LMC) - a satellite galaxy - is on a collision course ...

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 ...

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 ...

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 Milky Way is not the neat, flat pinwheel many of us learned about in school. Fresh data from precision star maps now show ...

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 ...

For years, astronomers have worried about how to explain why the Milky Way has fewer satellite galaxies than the standard dark matter model predicts. This is called the "missing satellites problem." ...

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 ...

Dozens of dwarf galaxies swarming around the Andromeda Galaxy like bees have been caught on camera by the Hubble Space Telescope, which took more than a thousand orbits of the Earth to take enough ...

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 ...

(Nanowerk News) Durham University’s cosmologists used a new technique combining the highest-resolution supercomputer simulations that exist, alongside novel mathematical modelling, predicting the ...
