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 ...

Studying the star, called SDSS J0715-7334, could give astronomers insights into how the universe's first stars were formed ...

A tiny object half a universe away, a scar in a stream of stars circling the Milky Way, and an unusual star cluster in a ...

The temperature difference is not subtle. One side of the Milky Way’s outer halo runs noticeably hotter than the other, a mismatch that has puzzled astronomers since it was measured.

A ghostly object orbiting the Milky Way has left astronomers questioning its composition: Is it a dark-matter-dominated dwarf galaxy or a star cluster bound by a hidden swarm of black holes? Ursa ...

How far the Milky Way's disc extends has long been difficult to define — it doesn't end sharply, but fades away gradually at its outer edges. Now, for the first time, an international team of ...

By analyzing the data from the Pan-Andromeda Archaeological Survey (PandAS), European astronomers have discovered a new satellite of the Andromeda galaxy. The newfound object, which received the ...

The Milky Way is a spiral galaxy containing 100-400 billion stars. Planet Earth sits along one of the galaxy’s spiral arms. Though the Milky Way is generally always visible from Earth, certain times ...

The Milky Way is our home galaxy with a disc of stars that spans more than 100,000 light-years. What you're looking at when the Milky Way is visible is the bright center of our galaxy with billions of ...

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 ...

How far the Milky Way's disk extends has long been difficult to define—it doesn't end sharply, but fades away gradually at its outer edges. Now, for the first time, an international team of ...

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