Astronomers used subtle warps in galaxy shapes to map the invisible forces shaping the universe. By reanalyzing years of telescope images, they studied more than 100 million galaxies across an ...

Scientists have discovered a giant cosmic filament where galaxies spin in sync with the structure that holds them together. The razor-thin chain of galaxies sits inside a much larger filament that ...

A team of astronomers looking at galaxies in the universe’s distant past have discovered nine young, compact galaxies, each weighing in at 200 billion times the mass of the Sun. Imagine receiving an ...

Whether the universe will “end” at all is not certain, but all evidence suggests it will continue being humanity’s cosmic home for a very, very long time. Our understanding of the future of the ...

A monster galaxy from the early universe shows that the cosmos was rich with oxygen when it was only less than 3% of its present age, astronomers have found. The discovery raises questions about how ...
