Wonderfest: Fast & Faraway: The High-Redshift Universe

 

In astronomy, the redder a galaxy appears, the faster it is fleeing, and the older a tale its light can tell. Such "redshifts" in the spectra of galaxies (symbolized with the letter "z") allow compelling insights. The recently-launched James Webb Space Telescope (JWST) has allowed astronomers to study the properties of high-z galaxies in existence only 250 million years after the Big Bang, when the universe was only 2% of its current age! How are these objects detected in such very "deep" space, and what are the early science results from this JWST research?
