Astronomers have achieved the most precise measurement ever of helium formed in the Big Bang's first five minutes, bringing us closer to understanding the Universe's birth. The breakthrough could help test the fundamental laws of physics themselves.
The James Webb Space Telescope captured stunning images of ancient galaxies, including one that formed just 800 million years after the Big Bang. Using a cosmic magnifying glass effect, astronomers are now seeing deeper into our universe's early history than ever before.
An international physics team has discovered that time itself might contain a fundamental uncertainty, suggesting there's a limit to how precisely any clock could ever measure it. The finding could finally reveal how quantum mechanics and gravity connect.
The James Webb Space Telescope just revealed that ancient galaxies might contain far more stars than scientists previously believed. This discovery could rewrite our understanding of how the universe formed its first massive galaxies.
Mysterious red dots in images from the early universe have puzzled scientists for years. Astronomers now believe they've identified an entirely new type of celestial object that could unlock secrets about how the cosmos formed.
Four years of James Webb Space Telescope discoveries reveal the early universe was far busier than scientists predicted. Galaxies formed faster, shone brighter, and appeared in greater numbers just hundreds of millions of years after the Big Bang.
The James Webb Space Telescope discovered a massive spiral galaxy nicknamed the Big Wheel that existed just two billion years after the Big Bang, challenging everything scientists thought they knew about how galaxies form. Five times more massive than our Milky Way, this cosmic giant shouldn't exist according to current models.
Scientists thought it was impossible to see ultraviolet light from galaxies in the early universe, but Hubble just spotted one blazing through the cosmic fog. This discovery shows how young stars cleared the universe's view 12 billion years ago.
Physicists at Brown University discovered why the universe expands at a steady pace instead of spiraling out of control. The answer lies in the shape of space-time itself, which acts like a cosmic safety switch.
Astronomers are closer to solving one of space's biggest mysteries: whether black holes or galaxies formed first. New evidence suggests black holes might have been the cosmic pioneers.
Scientists using the James Webb Space Telescope finally cracked the case of mysterious "little red dots" spotted in the early universe. The answer involves supermassive black holes wrapped in dense clouds of glowing gas.
The James Webb Space Telescope just discovered something that rewrites the cosmic rulebook: a massive black hole that existed before its galaxy finished forming. Scientists thought galaxies came first, but this tiny distant galaxy is proving them wrong.
