Inbox Astronomy: STScI Scientists Surprised to Find Brightness ‘Gap’ in Ancient Star Cluster

A similar gap was first identified in data from the <a href="https://www.esa.int/Science_Exploration/Space_Science/Gaia">Gaia</a> observatory of nearby stellar populations. However, it has never before been detected in a globular cluster. The gap provides clues to processes happening deep within the stars’ interiors.</p> <p>This finding would not have been possible without the software and techniques originally developed at STScI for NASA’s Hubble Space Telescope over more than two decades. These tools allowed the team to push the limits of Euclid, and in the future, the Roman Space Telescope.</p></div>  <br/><br/> </div>  <div style="text-align: center; max-width: 670px; margin-left: auto; margin-right: auto;"> <a href="https://www.stsci.edu/contents/news-releases/2026/news-2026-405.html?utm_source=stsci&utm_campaign=inbox_astronomy&utm_id=2026-405" style="text-align: center; width:160px; border: solid 3px #ec971f; background-color: #ec971f; color: white; font-size: 18px; font-family: Arial, Helvetica, sans-serif; border-radius: 4px; text-decoration: none; margin-left: auto; margin-right: auto;"><span style="text-decoration:none;">  Read more  </span></a> </div>  <p style="text-align: center;"> Find additional resources at <a href="https://www.stsci.edu?utm_source=stsci&utm_campaign=inbox_astronomy&utm_id=2026-405" style="color: #c76900; text-decoration: none;">www.stsci.edu</a> </p> <br> <br> <div style="text-align: center; background-color: #e5e5e5; font-size: 20px; width: 670px; margin-left: auto; margin-right: auto;">   <span style="font-size: 11px;">Please do not reply to this message.</span> <br/> <span style="font-size: 11px;">You are receiving this email because you are subscribed to the Inbox Astronomy mailing list.</span> <br/> <div style="font-size: 3px;">   </div> <span style="font-size: 11px;">Produced by the Space Telescope Science Institute's <a href="https://outreachoffice.stsci.edu" style="color: #c76900; text-decoration: none;">Office of Public Outreach</a> </span> <div style="font-size: 10px;">   </div> </div> <div style="text-align: center; height: 49px; background-color: black; color: white;border: solid 5px black;"> <a href="https://www.facebook.com/stsci/" title="Link to facebook" class="has-icon"> <img src="http://www.stsci.edu/files/live/sites/www/files/home/_images/icons/Facebook-icon-white.png" style="padding-top: 3px;"/> </a> <a href="https://twitter.com/spacetelescope" title="Link to X" class="has-icon"> <img src="http://www.stsci.edu/files/live/sites/www/files/home/_images/icons/X-icon.png" style="padding-top: 3px;"/> </a> <a href="https://www.instagram.com/space_telescopes" title="Link to instagram" class="has-icon"> <img src="http://www.stsci.edu/files/live/sites/www/files/home/_images/icons/Instagram-icon-white.png" style="padding-top: 3px;"/> </a> <a href="https://www.youtube.com/channel/UCQXVf-94-RV7NVTOhVCNTiQ" title="Link to youtube" class="has-icon"> <img src="http://www.stsci.edu/files/live/sites/www/files/home/_images/icons/YouTube-icon-white.png" style="padding-top: 3px;"/> </a> </div>
