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 Small Magellanic Clouds. The evidence is a stream of gas called the ...

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 ...

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 ...

A dwarf galaxy appears responsible for some of the universe’s most intense fast radio bursts. In A Nutshell Astronomers ...

Our search for exoplanets is focused on Milky Way stars. It's been successful, with more than 6,000 detected so far. Scientists are even beginning to move beyond mere detections, and working on ...

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 ...

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 ...

At the end of January, two articles were published almost simultaneously by members of the international DELVE collaboration in The Astrophysical Journal. Brazilians who are part of the DELVE ...

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 ...

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