The Milky Way galaxy is back in view in early-morning skies as seen from around the world. Check out this photo from a member of EarthSky's community. The post Milky Way season is starting first appeared on EarthSky.

We live in the Milky Way galaxy, an immense, flat, spiral galaxy surrounded by a massive halo of stars and dark matter. The disk of stars, gas, and dust in...

A new map of the center of the Milky Way galaxy reveals details of its magnetic fields

NASA astronaut Don Pettit used a camera with low light and long duration settings to capture this Jan. 29, 2025, image of the Milky Way appearing beyond

This is a journey into the scale of the galaxy we live in, the Milky Way, our home in the Universe. If you'd like to support my ongoing project to make educa...

A new radio-wave image of the center of our galaxy reveals all the forms of frenzy that a hundred million or so stars can get up to.

Astronomers have discovered what might be the speediest exoplanet system found so far. It moves at 1.2 million miles per hour (1.9 km per hour). The post Speediest exoplanet found near Milky Way center? first appeared on EarthSky.

Ursa Major III/UNIONS 1 (UMa3/U1 for short) is the least luminous and lowest-mass Milky Way satellite ever discovered, and possibly one of the most dark matter-dominated systems known.

How do you weigh a galaxy? It's an astronomical challenge, particularly if it's the galaxy you call home. It turns out there are several ways to get a handle on the mass of the Milky Way, and a recent study posted on the arXiv pre-print server summarizes these methods to present the best value.

One question for Miguel Aragon, a computational physicist at the National Autonomous University of Mexico.

A galaxy has been discovered that mirrors the very early version of our home galaxy, the Milky Way. The galaxy, dubbed the "Sparkler," is embedded in a system of globular clusters and satellite galaxies, and appears to be swallowing them as it grows. The research was published in Monthly Notices of the Royal Astronomical Society.

Streaming, batch, caching, archiving, encryption - data management can seem very complex. Read on for an ice-cream store metaphor that explains the options.

An animated dive into the dusty Milky Way reveals the outlines of our galaxy taking shape as we look out further and further from Earth. Based on new data from an interactive tool that exploits data from the European Space Agency's Gaia mission and other space science data sets, astronomers have created an animation to model dust in the Milky Way.

The Milky Way is destined to get a major makeover during an encounter with the Andromeda galaxy, predicted to happen 4 billion years from now.

The number of known galaxies circling the Milky Way is increasing as we develop new powerful telescopes.

The Milky Way and Andromeda merger has already begun. The two spiral galaxies will form one giant elliptical galaxy in 5 billion years.

Astronomers may have found corpses of ancient stars after mapping the Milky Way's massive cosmic graveyard.

Astronomers have spotted a gigantic void they believe to be a baryon acoustic oscillation — a relic from when the universe was a fiery plasma soup
