Cosmic archeologists have used the James Webb Space Telescope to excavate ancient disk galaxies that tell the story of how ...

For the first time, astronomers have glimpsed a young star outside the Milky Way galaxy that’s ringed by a dense disk where planets may form. The massive star, called HH 1177, and its rotating ...

The thin disk is about 2,000 light-years thick in our part of the galaxy. “The Milky Way has been quite quiet for the last 8 billion years,” Xiang says, experiencing no further encounters with ...

The disk itself could be up to 12,000 astronomical units across, where 1 astronomical unit, or AU, is the average Earth-Sun distance of 93 million miles (150,000 kilometers).

Astronomers have identified the oldest stellar disk in the Milky Way, a discovery that reshapes our understanding of the galaxy's formation. This early disk, known as PanGu, is over 13 billion ...

(CNN) — Astronomers have spotted a massive disk galaxy, not unlike our own, that formed 12.5 billion years ago when our 13.8 billion-year-old universe was only a tenth of its current age. But… ...

The research, ‘A cold, massive, rotating disk galaxy 1.5 billion years after the Big Bang’, is published in Nature today. More about Space Alma the universe. Join our commenting forum.

According to a study published Wednesday in the journal Nature, the 12.5 billion-year-old rotating galactic disk formed much earlier than astronomers thought possible for a galaxy of its size.

It’s the relative movements of our galaxy and this disk that may trigger events that lead to mass die-offs. “There’s a cycle in our galaxy; ...

The massive star, called HH 1177, and its rotating disk were spotted in the Large Magellanic Cloud, a neighboring dwarf galaxy that’s about 160,000 light-years away.
