Astronomers have found the boundary of star formation in the Milky Way's spiral disk — and it's not as far out from the ...

New simulations show that early ultraviolet light controlled whether ultra-faint dwarf galaxies could form stars.

The Milky Way may not have a sharp edge, but scientists have now found where its star-forming activity largely comes to an ...

Citizen science project uses Euclid telescope data to find gravitational lenses. Public helps identify light-bending galaxies ...

A new study suggests that most "post-starburst galaxies" cease star formation because they run out of fuel. But that's not ...

Scientists have uncovered the true boundary of the Milky Way’s star-forming region using stellar “age mapping.” They found a ...

In the vast darkness of the early universe, a spiral of light named Zhúlóng offers a new glimpse into cosmic history. This galaxy, shaped like our Milky Way, formed just a billion years after the Big ...

Understanding the universe as a whole requires simulations on cosmic scales. An international team of astrophysicists, with a ...

Ultra-faint dwarf galaxies—tiny satellite galaxies orbiting the Milky Way—have long been seen as cosmic fossils. Now, a new ...

Astronomers have identified a compact, superheated galaxy in the early universe that is churning out new suns at roughly 180 times the rate of the Milky Way, turning a tiny patch of sky into a cosmic ...

The study of galaxies and their star formation processes remains a cornerstone of modern astrophysics. Galaxies are the fundamental building blocks of the Universe, each hosting a complex interplay of ...
