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.
NASA's Hubble Space Telescope just completed the most detailed star map ever created of our neighboring Andromeda galaxy, measuring 200 million individual stars across two-thirds of its disk. The breakthrough gives scientists an unprecedented window into how galaxies like our own Milky Way evolve over billions of years.
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 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.
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.
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.
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 using powerful telescopes discovered 70 ancient galaxies that formed earlier than our models say should be possible. These cosmic time capsules could rewrite the story of how stars and galaxies came to be.
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.
The James Webb Space Telescope is discovering galaxies so old and bright they're forcing scientists to rewrite theories about the universe's first moments. These impossible galaxies are revealing that the early cosmos was far more complex than anyone imagined.
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 have discovered a galaxy frozen in time from just 800 million years after the Big Bang, revealing what the universe looked like before stars created the building blocks of life. This ancient galaxy contains almost no heavy elements, making it the most chemically primitive ever observed.
Astronomers discovered remnants of a dwarf galaxy our Milky Way devoured 10 billion years ago, offering new clues about how our cosmic home grew from a smaller galaxy into the massive spiral we call home today.
NASA's James Webb Space Telescope just captured a breathtaking new image of a spiral galaxy 45 million light-years away, revealing star nurseries and cosmic structures never seen this clearly before. The galaxy's tentacle-like filaments earned it a fitting nickname: the Squid Galaxy.
The James Webb Space Telescope spotted a massive stellar bar in a galaxy that existed when the universe was just one-tenth its current age. This discovery challenges everything astronomers thought they knew about how early galaxies evolved and may solve the mystery of why some ancient galaxies suddenly stopped forming stars.
NASA's James Webb Space Telescope discovered a unique "stingray" galaxy that finally explains one of astronomy's strangest puzzles. Scientists believe these mysterious cosmic objects aren't a new type of galaxy at all, but a brief evolutionary phase every galaxy goes through.
NASA's James Webb Space Telescope just revealed a stunning portrait of galaxy M77, glowing brilliantly thanks to a supermassive black hole at its heart. The image shows beams of light radiating from the galaxy's center 47 million light-years away.
Amateur astronomers are getting their telescopes ready as spring arrives, bringing the best window of the year to see distant galaxies from the northern hemisphere. Thousands of spectacular galaxies become visible as Earth tilts away from the dusty Milky Way plane.
NASA's James Webb Space Telescope captured stunning new images of the Cigar Galaxy, revealing millions of stars hidden behind cosmic dust. The infrared views show a galaxy in the midst of an explosive star-forming phase 12 million light-years from Earth.
