A dark galaxy. AC G185.0-11.5 is part of the larger AC-I Complex, which is what astronomers call a high-velocity cloud (HVC). These are clumps of hydrogen moving up to several hundred mph faster ...

Researchers discovered the first ultra-faint dwarf galaxies to be found around a spiral galaxy with the mass of the Milky Way that’s outside of the Local Group, the clustering of galaxies that ...

At a distance of around 11.4 million years away from Earth, the ultra-faint galaxies are the first to be found orbiting a Milky Way-like galaxy outside of our galaxy's cosmic backyard, known by ...

The James Webb Space Telescope (JWST) has spotted the smallest galaxy outside our local universe by using the heaviest known cluster of galaxies, called El Gordo, as a giant lens. El Gordo was ...

Galaxies are incredibly complex systems that we are still struggling to understand,” observed Enrico Congiu of the European Southern Observatory, conveying the wonder that met release of the sharpest ...

It exists with over 50 other galaxies called the Local Group, which also includes Andromeda. In orbit around the Milky Way are a number of dwarf galaxies, ...

Our Local Group will survive the coming expansive annihilation, but Laniakea will not. We will never even reach the Virgo cluster, let alone the site of the Great Attractor.

The SETI Institute recently began searching for signs of advanced extraterrestrial civilizations in distant galaxies outside our own. Using the Murchison Widefield Array (MWA) in Western Australia ...

A collision between our Milky Way galaxy and its largest neighbor, the Andromeda galaxy, predicted to occur in about 4.5 billion years, has been anticipated by astronomers since 1912. But new ...
