A distant galaxy nicknamed "Cosmic Grapes" is bursting with massive star-forming clumps — far more than expected — offering ...

In a groundbreaking study published in the Astrophysical Journal Letters, scientists have reevaluated the nature of Ursa ...

The impending merger of the two galaxies hints at what might be in store for the Milky Way and the Andromeda galaxy if and ...

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 ...

New evidence suggests that a dwarf galaxy orbiting the Milky Way called Ursa Major III is actually a star cluster.

What's more, new satellite candidates are still being discovered, she added. Geha studies the origin and evolution of dwarf galaxies, and when she started her research more than two decades ago, the ...

Ursa Major III, once considered a dark-matter-dominated dwarf galaxy, may actually be a dense star cluster. New research suggests its gravity is maintained by a core of black holes and neutron stars, ...

Astronomers have studied the merger of galaxies NGC 5713 and NGC 5719 to understand the future collision between the Milky ...

In recent groundbreaking research published in Monthly Notices of the Royal Astronomical Society, scientists from the ...

Surveying the Milky Way's entire satellite system in such a comprehensive way is very challenging because we are embedded inside our galaxy. Nor can it be accomplished for other large galaxies ...

The Milky Way could have many more satellite galaxies than scientists have previously been able to predict or observe.

The nearest galaxy of comparable mass to the Milky Way beyond Andromeda is M81, at nearly 12 million light-years. This bird's-eye view of Andromeda's satellite system allows us to decipher what ...
