JWST Completes a Huge Survey of the Earliest Galaxies

The James Webb Space Telescope has a number of science goals. One of them is to help understand the evolution of galaxies and their formation within the first billion years after the Big Bang. Astronomers have completed an initial Webb telescope survey that discovered 1,700 galaxy groups. Many of these groups date back to when the Universe was less than 1 billion years old. The survey spans 12 billion years of cosmic history, from these ancient …

JWST Spectral Stacking Reveals New Insights Into Galaxies In Epoch Of Reionization

JWST's spectral stacking reveals weaker low-ionization species absorption and smaller blueshifted velocity centroids in high-redshift galaxies, suggesting lower HI covering fractions and higher ionizing photon escape rates during the epoch of reionization.

The unknown attracts us. Coloquially, we are curious to learn about what surrounds us, and not only in our world, but beyond our atmosphere. Is there life beyond our planet? Are there other universes? There is not yet scientific evidence to prove it, but theories. One of them is string theory, which estimates that there are around 11 dimensions and each of them contains between 10 and 500 universes.
