Multi-star system FS Tau captured by the Hubble Space Telescope. "Jets emerge from the cocoon of a forming star to blast ...

the James Webb Space Telescope (JWST) has uncovered the hidden mysteries of the W51 star-forming region, giving astronomers an unprecedented view of young, massive stars that were previously obscured ...

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 ...

Astronomical observations show that the most massive galaxies in the early universe formed approximately three to four billion years after the Big Bang and stopped producing stars very early in cosmic ...

Massive stars have an outsized influence on their environment and the galaxies they call home. These behemoths have the highest surface temperatures of any normal stars, so they emit copious amounts ...

This starmap shows the full extent of the Greater Pleiades Complex as it would appear on the Pasadena night sky if every star in it were visible. Of the 3,019 stars that make up the complex, 1,631 are ...

A nearby active galaxy called VV 340a offers a dramatic look at how a supermassive black hole can reshape its entire host. Astronomers observed a relatively weak but restless jet blasting outward from ...

Scientists have uncovered the true boundary of the Milky Way’s star-forming region using stellar “age mapping.” They found a telltale U-shaped pattern showing that star formation drops sharply around ...

Inside-out growth and stellar migration in the Milky Way: Inside the star-forming disc (within ~12 kpc), abundant cold gas fuels continuous star formation, producing young stars. Beyond this break ...
