Astronomers have been confounded by recent evidence that the universe expanded at different rates throughout its life. New ...

Most cosmologists believe that these stars were the first large, free-floating structures to illuminate our universe, and that black holes appeared later. But some have proposed that it went the other ...

Black holes are eaters of all things, even radiation. A new study published in Physical Review Letters suggests that black ...

Cosmologists can now explore data faster than ever before with a new emulator. As astronomers continue to uncover the mysteries of the universe, their work generates increasingly vast and intricate ...

The universe is approaching the midpoint of its 33-billion-year lifespan, a Cornell physicist calculates with new data from ...

A representation of the evolution of the universe over 13.77 billion years. NASA's Goddard Space Flight Center Astronomers have long understood that the universe is expanding—in other words, the space ...

Matrix models have emerged as a powerful framework in theoretical physics, offering a nonperturbative approach to describing quantum space-time. In these models, fundamental degrees of freedom are ...

Astronomers have discovered a rare group of five dwarf galaxies located relatively close to Earth; these galaxies exist in a near-perfect alignment, resembling a string of cosmic pearls in the sky.
