Astronomers have confirmed the earliest barred spiral galaxy in the universe, a Milky-Way-like structure that existed just 2 ...

All of the people and mountains and planets and stars that you see around you only make up 15% of the universe's mass. The rest of it is dark matter.

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, ...

Researchers from the South Pole Telescope project team looked deep into the center of the Milky Way, discovering powerful, surprising bursts of light from two accreting white dwarf systems.

How can a galaxy display perfectly defined spiral arms when the Universe had only a little over 10% of its current age? This surprising discovery challenges established models about the birth and ...

The James Webb Space Telescope has upended expectations again, revealing a massive spiral galaxy in the universe’s infancy that looks strikingly like a young Milky Way. Instead of a chaotic, ...

Forbes contributors publish independent expert analyses and insights. An award-winning reporter writing about stargazing and the night sky. When will the Milky Way collide with the Andromeda Galaxy?

New supercomputer simulations suggest the Milky Way could be surrounded by dozens more faint, undetected satellite galaxies—up to 100 more than we currently know. These elusive "orphan" galaxies have ...

In recent years, one of the most troubling puzzles in astrophysics has grown more urgent. Scientists have realized that the universe seems to be expanding faster than expected, throwing a wrench into ...

This is the reality for astronomers today, who are capturing faint signals that have traveled for over 13 billion years to reach Earth. These signals originate from a time when the universe was still ...

In this combination of images from NASA/ESA shows three future scenarios for Milky Way & Andromeda encounter. Top left: Galaxies bypass at 1 million light-year separation. Top right: At 500,000 ...

Scientists at Nagoya University in Japan shared new insights into the motion of massive stars in a nearby galaxy that could completely transform our understanding of galaxy evolution and interactions.
