The unexplained cause of the slowed growth of the cosmic web that connects galaxies could hint at new physics.
The universe was briefly governed by different physical laws than exist today, according to new research.
The cosmic web is a vast structure connecting the entire universe, and new measurements point to a mysterious anomaly.
What happened immediately after the Big Bang? Scientists used Bose-Einstein condensate and sound waves to try and find an answer.
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.
Under the plan satellites will orbit the Moon, which will block out noise from Earth, in order to probe the early universe.
A relic, a fossil, and a halo are among the bizarre features that defy existing theories, according to a new study.
Scientists glimpsed the distribution of dark matter around galaxies 12 billions of years ago, which is much earlier than previous studies.
The object was spotted some 300 million years after the Big Bang, making it potentially the oldest known galaxy.
Scientists were able to “fast-forward” simulations of ancient galaxy clusters to our present day in a first-of-its-kind study.
A surprise discovery in the early universe has major consequences for the evolution of black holes and galaxies.
At 13.5 billion light-years from Earth, a galaxy called HD1 is on the cosmic frontier.
