<p>When the James Webb Space Telescope was launched at the end of 2021, 
we expected stunning images and illuminating scientific results. So far,
 the powerful space telescope has lived up to our expectations. The JWST
 has shown us things about the early Universe we never anticipated.</p>
<p>Some of those results are forcing a rewrite of astronomy textbooks.</p><p><span class="gmail_default" style="font-family:arial,sans-serif;font-size:small;color:rgb(0,0,0)"><</span><a href="https://www.universetoday.com/167269/the-jwst-is-re-writing-astronomy-textbooks/" target="_blank">https://www.universetoday.com/167269/the-jwst-is-re-writing-astronomy-textbooks/</a><span class="gmail_default" style="font-family:arial,sans-serif;font-size:small;color:rgb(0,0,0)">></span></p><p><span class="gmail_default" style="font-family:arial,sans-serif;font-size:small;color:rgb(0,0,0)">Quotes:<br></span></p><p>The Early Universe is one of the JWST’s primary scientific targets. 
Its infrared capabilities allow it to see the light from ancient 
galaxies with greater acuity than any other telescope. The telescope was
 designed to directly address confounding questions about the 
high-redshift Universe. </p>
<p>The following three broad questions are foundational issues in cosmology that the JWST is addressing. </p><div id="m_7873713219634620406gmail-unive-66fde5cc3c2ba605a033019ffbcaf741"></div>
