Understanding how the Milky Way formed means looking far beyond the bright spiral you see in the night sky. A new study led ...

How galaxies assemble their stars and grow over billions of years remains one of the central questions in astronomy. Recent ...

Three of the oldest stars in our universe have been discovered, and they were lurking right under our noses this whole time, and traveling in the wrong direction The heavenly bodies were detected by ...

New simulations of Milky Way-like galaxies reveal that the strange split between two chemically distinct groups of stars may arise from several very different evolutionary events. Bursts of star ...

The mystery of galaxies in the early Universe just got even weirder. A team of astronomers has identified a giant spiral galaxy so well-formed that it already has a stable galactic bar; a long, ...

A mysterious excess of far-ultraviolet light seen across the Milky Way could come from the annihilation of clumpy dark matter ...

Astronomers reanalyzed the chemical composition of three stars in the Milky Way's halo and found that they are between 12 and 13 billion years old. They may have also been stolen from other galaxies.

An MIT astronomy class has found three of the oldest stars in the universe lurking right outside the Milky Way. The stars, about 30,000 light-years from Earth, are in the galaxy's "halo," the cloud of ...

Galaxies from the early Universe are more like our own Milky Way than previously thought, flipping the entire narrative of how scientists think about structure formation in the Universe, according to ...

To find the universe’s oldest stars, you must look for the ones with low chemical abundances and a retrograde orbit. That’s what a group of students in a class of MIT professor of physics and division ...
