Galaxy mergers aren't always obvious

The galaxy Centaurus A is about 11 million light-years away and is the fifth-brightest galaxy in the sky. Because it's so bright, it's been studied extensively by amateur and profe...

James Webb Space Telescope catches 6 galaxies merging into one of the largest galaxies in the universe

A supermassive black hole is also coming together at the heart of this galaxy maelstrom.

The little red galaxies that may be sending us neutrinos

Peering far into the distant, high-redshift universe, the James Webb telescope has discovered an abundance of small red galaxies known as the Little Red Dots. From their observatio...

Hubble Spots Two Galaxy Clusters in the Process of Merging

This NASA Hubble Space Telescope image features a galaxy cluster, called CL0016+1609 or MACS J0018.5+1626, that is very bright at X-ray wavelengths and is one of the most extensive...

Black holes buried in mysterious 'little red dot' galaxies could blast cosmic ghosts at Earth

Mysterious "little red dots" discovered in the early universe by the James Webb Space Telescope could harbor buried black holes that fire high-energy neutrinos through the cosmos.

Galaxy Groups Hiding in the Universe’s Emptiest Places

Even the universe’s emptiest regions, the vast voids that make up most of the volume of space, are not entirely empty. A new study using the CAVITY survey hunts for galaxy groups h...

Scientists find 3 supermassive black holes on the verge of collision inside a distant galaxy

A greedy galaxy that existed less than 1.3 billion years after the Big Bang is hoarding supermassive black holes.

World's largest digital camera captures more than 500,000 galaxies in deep view of universe

The Vera C. Rubin Observatory has released a stunning image of the COSMOS field. This image contains over half a million galaxies and fifty thousand stars. Astronomers have studied...

Galaxy Mergers Aren't Always Obvious

Mergers are a part of a galaxy's life in this Universe. Though clear signs of these mergers fade over hundreds of millions of years, evidence is still present, yet obscured, in the...

NASAs new views of a famous galaxy are more than a screensaver

NASA's James Webb Space Telescope peers into Centaurus A, revealing millions of stars and a hungry black hole at the galaxy's core.

Astronomers spot an extremely rare galaxy mega-merger

Scale in the universe is hard to understand from a purely human perspective. Many times, the math just doesn't sit well with our brains, which evolved to capture and process data a...

Astronomers Spot an Extremely Rare Galaxy Mega-Merger

Scale in the universe is hard to understand from a purely human perspective. Many times the math just doesn’t sit well with our brains that evolved to capture and process data abou...

In this July 6, 2026, image, NASA's James Webb Space Telescope's Mid-Infrared Instrument (MIRI) reveals the nearby galaxy Centaurus A, exposing the dusty structures and hidden acti...

Milky Way-like simulation reveals how central galactic structures grow together

Understanding the formation and evolution of the centers of galaxies is one of the most intriguing challenges in astrophysics. The new study aims to unveil the physical processes t...

Webb's 'little red dots' puzzled astronomers; this galaxy may hold the answer

How an ancient collision with another galaxy transformed the Milky Way

The Milky Way has a secret history of galaxy mergers that we are only now starting to uncover.

Video: Thousands of planets are hidden in this image

Millions of stars. Thousands of hidden worlds. One unprecedented view of our galaxy. Three years since launch, ESA's Euclid space telescope reveals the center of the Milky Way gala...

Diffuse puffs of “missing” matter surround most galaxies

Stars and galaxies make up much of the universe’s ordinary, observable matter. But for decades, scientists have wrestled with a cosmic conflict: There should be much more.  Physici...

Three Supermassive Black Holes Found in a Galaxy From the Dawn of the Universe

Three supermassive black holes in a distant and therefore very old galaxy offer a glimpse into how black holes merged and grew in the early universe. Light from the galaxy J0148-42...

The Milky Ways center holds the ruins of another ancient galaxy

Using NASA's Hubble Space Telescope, astronomers discovered evidence of a galaxy merger in the Milky Way's ancient history.

Astronomers catch massive galaxy assembling piece by piece 1.2 billion years after Big Bang

Astronomers have discovered a remarkably tiny group of six young galaxies just 1.2 billion years after the Big Bang. This may be a rare glimpse of how some of the universe's larges...

'Hidden stars' suggest that distant galaxies are much more massive than they appear

Astronomers have discovered that the most massive galaxies in the early universe contain far more small stars than expected. As a result, these early galaxies were likely much more...

Hubble, James Webb Space Telescope team up to capture the 'Black Eye Galaxy' | Space photo of the day for Aug. 18, 2026

The "Black Eye Galaxy" is captured in a gorgeous new composite image from the Hubble and James Webb space telescopes.

Probing binary stars in the Small Magellanic Cloud with the JWST

The formation and evolution of individual stars in a galaxy shape the evolution of the galaxy itself. Stars and stellar remnants make up the vast majority of a galaxy's mass, so it...
