New Observations Reveal How Giant Structures In Space Connect the Universe and Form Galaxies
The cosmic web is a vast and mysterious structure that forms the universe, and we're learning how it shapes galaxies that host stars and planets.
Distant Galaxies Spotted by James Webb May Not Be So Distant Due to Errors
The James Webb Space Telescope is so good at capturing ancient light that some early discoveries may now need a “second look,” one scientist says.
The Universe’s Oldest Light Reveals Unprecedented Dark Matter Patterns
Scientists glimpsed the distribution of dark matter around galaxies 12 billions of years ago, which is much earlier than previous studies.
James Webb Spots the Farthest Galaxy Humans Have Ever Seen, Near the Dawn of Time
The object was spotted some 300 million years after the Big Bang, making it potentially the oldest known galaxy.
'Time Machine' Simulation May Uncover Secrets of Cosmic Web Connecting Universe
Scientists were able to “fast-forward” simulations of ancient galaxy clusters to our present day in a first-of-its-kind study.
An Ancient Galaxy Collision Sheds Light on Dark Matter
Scientists think they might have explained the bizarre discovery of unusual galaxies free of dark matter.
Ancient Black Holes Have Revealed a Mystery at the Edge of Time and Space
A surprise discovery in the early universe has major consequences for the evolution of black holes and galaxies.
Space Has Invisible Walls Created by Mysterious 'Symmetrons,' Scientists Propose
Scientists invoke “new physics” to explain the weirdly synced-up “satellites” observed around the Milky Way and other nearby galaxies.
Scientists Discover Most Distant Alien Galaxy, and It Defies Explanation
At 13.5 billion light-years from Earth, a galaxy called HD1 is on the cosmic frontier.
Scientists Discover Most Distant Star That Humans Have Ever Seen
"Earendel" was spotted about 900 million years after the universe was born, making it by far the most distant star ever seen.
A Cosmic Web Connecting the Universe Shapes Dark Matter in Galaxies, Study Finds
Galaxies located at cosmic web “nodes” assemble dark matter earlier, and are more enriched with heavy elements, compared with those that are further away.
A Vast ‘Faint Universe’ of Rogue Stars Is Revealing Dark Matter
Stars that have been kicked out of their galaxies preserve a cosmic “fossil record,” according to a new study.
