Ethan Siegel<p>JWST discovers how we’re able to see the Universe at all It's only because all of the neutral atoms in intergalactic space became ionized that we can see so far away through space.

A team of researchers used the James Webb Space Telescope to examine this galaxy, estimating that it dates back to about 330 million years after the Big Bang. The surprise came from the so-called Lyman-alpha radiation because it was much stronger than expected from a galaxy of that era.</p><p><a href="https://english.tachyonbeam.com/2025/03/27/an-intense-primordial-light-from-the-dark-ages-of-the-universe/" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">english.tachyonbeam.com/2025/0</span><span class="invisible">3/27/an-intense-primordial-light-from-the-dark-ages-of-the-universe/</span></a></p>
