For the first time, astronomers have directly imaged the faint glow of the diffuse cosmic web that stretches throughout the known the universe.
New results from the Keck Cosmic Web Imager, or KCWI, which was designed by Caltech’s Edward C. Stone Professor of Physics Christopher Martin and his team, are the first to show direct light emitted by the largest and most hidden portion of the cosmic web: the crisscrossing wispy filaments that stretch across the darkest corners of space between galaxies. The KCWI instrument is based at the W. M. Keck Observatory atop Maunakea on the Big Island.
TThe discovery of the billion-light-year-wide Baryon Acoustic Oscillation (BAO) is not only an exciting find, but also a curious one.
Astronomers have used the James Webb Space Telescope to discover a 3 million light-year-long strand of galaxies that formed just 830 million years after the big bang. The filament is one of the earliest structures of the cosmic web, the network of galaxies that fills the universe. https://youtu.be/9MwJ5_MExu0 Galaxies are not scattered randomly across the…
The James Webb Space Telescope spotted a long, narrow filament of ten galaxies that existed 830 million years after the Big Bang.
