A rare star reveals how the Universe's first stars exploded, helping explain the Milky Way’s outer halo and its unusual chemistry.

The Lambda Cold Dark Matter (LCDM) theory suggests that most galaxies are low-mass dwarf galaxies, many of which orbit larger galaxies like the Milky Way. More broadly, the LCDM represents our best ...

A team of astronomers led by researchers at the University of Groningen has identified a colossal sheet of dark matter and ...

In recent groundbreaking research published in Monthly Notices of the Royal Astronomical Society, scientists from the University of Queensland have provided insights into the likely fate of our galaxy ...

New supercomputer simulations suggest the Milky Way could be surrounded by dozens more faint, undetected satellite galaxies—up to 100 more than we currently know. These elusive "orphan" galaxies have ...

This map is part of ACES — the ALMA CMZ Exploration Survey — a project designed to understand how gas condenses into stars in the extreme and chaotic environment at the heart of our galaxy. The survey ...

The oldest stars in the Milky Way are forcing a fresh look at one of cosmology’s biggest arguments. If some of them are about 13.6 billion years old, as a new analysis suggests, then the universe ...

Well, it’s confession time: I’ve been lying to you. I’ve said on many occasions in this column that our Milky Way galaxy has a flat disk. But it’s not really flat—not according to any reasonable ...

Scientists using the ALMA telescope have created the most-detailed-ever map of the Milky Way's chaotic center. The observations could open a window to the ancient universe as it appeared shortly after ...

Scientists from Helsinki, Durham and Toulouse universities used data from NASA’s Hubble and the European Space Agency’s Gaia space telescopes to simulate how the Milky Way and Andromeda will evolve ...

Researchers may have identified what could be a compelling clue in the ongoing hunt to prove the existence of dark matter. A mysterious diffuse glow of gamma rays near the center of the Milky Way has ...
