Scientists discovered our galaxy merged with a dwarf galaxy 11.8 billion years ago, revealing a crucial chapter in how our cosmic home was built. The collision helped transform the young Milky Way into the spiral galaxy we know today.
NASA wants your help spotting cosmic clues in stunning new telescope images. Anyone with a smartphone can join Galaxy Zoo: Tidal Tales and help astronomers understand how galaxies grow and change.
Astronomers discovered a powerful cosmic explosion coming from a tiny, hidden galaxy nestled inside an ancient stream of gas and dust. The collision of two neutron stars inside this mini-galaxy could solve mysteries about where precious metals like gold and platinum come from.
Scientists just confirmed our home galaxy grew from a massive collision with another galaxy 12 billion years ago, revealing how the Milky Way became the cosmic neighborhood we know today. The discovery shows our galaxy has been growing by absorbing neighbors since nearly the beginning of time.
Scientists finally figured out why a neighboring galaxy has been spinning strangely for decades. A catastrophic collision with its larger sister galaxy millions of years ago left it reeling in a cosmic twist.
Scientists found the remains of an ancient dwarf galaxy buried inside our own Milky Way, consumed billions of years ago. The discovery reveals new clues about how galaxies grow and evolve over time.
Astronomers discovered neutron stars colliding in one of the smallest, faintest galaxies ever observed, solving a decades-old mystery about gamma-ray bursts. The finding shows that universe-shaking cosmic events happen in places we never thought to look.
NASA's James Webb Space Telescope just celebrated four years in space by peering through cosmic dust to reveal millions of stars never seen before in nearby galaxy Centaurus A. The images show not just clearer views, but an entirely different story of a galaxy still recovering from a violent collision two billion years ago.
The James Webb Space Telescope caught five galaxies colliding when the universe was barely 800 million years old, rewriting what we thought about how galaxies form. The discovery could finally explain one of Webb's biggest mysteries.
A Texas astrophotographer captured two galaxies merging 45 million light-years away in a cosmic dance that's been unfolding for hundreds of millions of years. The breathtaking image reveals star clusters being born in the collision's spectacular tidal tails.
The James Webb Space Telescope discovered a 2-billion-year-old galaxy that isn't rotating, a behavior scientists only expect in much older galaxies. The finding challenges our understanding of how early galaxies formed and evolved.
NASA's most powerful space telescope marks its fourth birthday by revealing the hidden heart of a galaxy born from an ancient cosmic collision. The stunning infrared images show what no telescope has ever seen before.
The James Webb Space Telescope captured an extraordinary view of Centaurus A, a galaxy reborn from a cosmic collision 2 billion years ago. The infrared images reveal what was hidden before: glowing clouds, graceful ribbons of stardust, and the breathtaking aftermath of galactic healing.
The James Webb Space Telescope spotted a galaxy that shouldn't exist by current theories: a massive, ancient galaxy with no rotation, formed less than 2 billion years after the Big Bang. This discovery could rewrite what we know about how galaxies form and evolve.
Scientists discovered three dwarf galaxies dancing together in a rare gravitational trio near the Andromeda Galaxy, revealing new secrets about how small galaxies survive in cosmic neighborhoods. The finding shows that even in the vast universe, companions stick together.
A breathtaking new image reveals the Sombrero galaxy in unprecedented detail, showing why it's become one of astronomers' favorite cosmic targets. The hat-shaped wonder sits 28 million light-years away and holds nearly 10 times more star clusters than our own Milky Way.
Astronomers using the James Webb Space Telescope discovered powerful "galaxy-killing" winds that blow away the gas needed to form new stars, finally explaining why so many massive galaxies in the early universe died young. The finding shows how rapidly growing galaxies essentially destroyed themselves.
NASA's Chandra X-ray Observatory just unveiled 16 breathtaking images of galaxies across the universe, combining decades of data into cosmic masterpieces. These spectacular photos reveal spiral arms, ancient stars, and even colliding galaxies that help us understand our own place in the cosmos.
The James Webb Space Telescope discovered five galaxies merging just 800 million years after the Big Bang, billions of years earlier than scientists thought possible. The finding rewrites our understanding of how quickly the early universe came together.
Astrophotographer Greg Meyer spent 21 hours capturing a stunning image of two galaxies colliding in deep space, revealing a cosmic dance that's been unfolding for hundreds of millions of years. The breathtaking photo shows the Antennae Galaxies locked in a gravitational embrace that's creating thousands of new stars.
