The older stars migrated out from the galactic center, leaving the younger ones inside.

How far the Milky Way's disk extends has long been difficult to define—it doesn't end sharply, but fades away gradually at ...

The Wolfe Disk, a massive rotating disk galaxy in the early universe, was discovered in 2017 when a stargazing project in the Chilean desert examined light from a distant quasar (top left) absorbed in ...

European astronomers have used the Atacama Large Millimeter Array (ALMA) and the James Webb Space Telescope (JWST) to observe ...

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) found a young star surrounded by an astonishing mass of gas. The star, called 49 Ceti, is 40 million years old and ...

Astronomers have discovered the edge of the Milky Way’s star-forming disk, revealing that most new stars form within 40,000 ...

What specific processes are responsible for planetary formation and evolution? This is what a recent study published in Astronomy & Astrophysics hopes to address as an international team of ...

When a star passes too close to a supermassive black hole, tidal forces tear it apart, producing a bright flare of radiation as material from the star falls into the black hole. Astronomers study the ...

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 ...
