NASA's James Webb Space Telescope has picked up an unusual signal from the dawn of time that could reveal secrets about how our universe began. Scientists are calling the discovery potentially groundbreaking for our understanding of cosmic history.
Astronomers have unlocked a new way to read a galaxy's past, tracing 12 billion years of cosmic history through chemical fingerprints in space. The breakthrough opens an entirely new field called "extragalactic archaeology" that could reveal how our own Milky Way formed.
The James Webb Space Telescope has spotted a surprisingly mature spiral galaxy with a bright stellar bar at its center, formed just 2 billion years after the Big Bang. The discovery pushes back our understanding of how quickly complex galaxies could take shape in the early universe.
Scientists think mysterious "Little Red Dots" spotted by the James Webb Space Telescope could be cosmic nurseries where the universe's first giant black holes formed. This discovery might solve the puzzle of how supermassive black holes appeared so early in cosmic history.
After analyzing six years of data from 669 million galaxies, scientists have created the clearest picture yet of dark energy, the mysterious force making our universe expand faster every year. Four different cosmic observation methods came together for the first time to reveal how this invisible force has shaped 6 billion years of cosmic history.
