If we look on large enough scales, matter should be distributed evenly, with no preferred direction within the cosmos. This is known as the cosmological principle.

Faced with observations of early black holes and galaxies that weren’t expected to exist, scientists have come up with a ...

The James Webb Space Telescope has found nearby brown dwarfs masquerading as far-distant galaxies. The discovery reinforces how, in astronomy, what you see isn’t always what you get ...

The first half of 2026 brought five major space discoveries that challenged existing scientific theories, from record-breaking black holes and an ancient interstellar comet to surprising findings ...

Some of the hardest questions in cosmology begin where the usual math gives up. Push Einstein’s theory far enough back toward the Big Bang, and the equations run into a singularity, a point where ...

Distant galaxies that abruptly stopped making stars have puzzled astronomers for years. About 9 billion years ago, during one ...
