This dazzling NASA image shows the biggest super star cluster in our galaxy

<p>The <a data-i13n="cpos:1;pos:1" href="https://www.engadget.com/the-webb-telescopes-dazzling-nebula-image-supports-a-long-held-theory-210229206.html">James Webb Space Telescope[/url] continues to capture images of space that are clearer and more detailed than what we've seen before. One of the latest images it has taken is of a &quot;super star cluster&quot; called Westerlund 1, and it <a data-i13n="cpos:2;pos:1" href="https://esawebb.org/images/potm2409a/">shows an abundant collection[/url] of heavenly bodies, shining brightly like gemstones. Super star clusters are young clusters of stars thousands of times bigger than our sun that are all packed in a small area. Our galaxy used to produce more clusters billions of years ago, but it doesn't churn out as many stars anymore, and only a few super star clusters still exist in the Milky Way.&nbsp;</p>
<p>Westerlund 1 is the biggest remaining super star cluster in our galaxy, and it's also the closest to our planet. It's located 12,000 light-years away, made up of massive stars between 50,000 and 100,000 times the mass of our sun within a region that measures six light-years across. Those stars include yellow hypergiants that are around a million times brighter than our sun, as well. Since the stars populating the cluster have a comparatively short life, scientists believe it's only around 3.5 to 5 million years old. That's pretty young in the cosmic scale. As such, it's a valuable source of data that could help us better understand how massive stars form and eventually die. We won't be around to see it, but the cluster is expected to produce 1,500 supernovae in less than 40 million years.&nbsp;</p>

To take the image, they used Webb's Near-InfraRed Camera (NIRCam), which was also recently used to capture a <a data-i13n="cpos:3;pos:1" href="https://www.engadget.com/science/space/nasas-latest-supernova-image-could-tell-us-how-fast-the-universe-is-expanding-130005672.html">gravitationally lensed supernova[/url] that could help shed light on how fast our universe is expanding.&nbsp;</p>This article originally appeared on Engadget at https://www.engadget.com/science/space/this-dazzling-nasa-image-shows-the-biggest-super-star-cluster-in-our-galaxy-120053279.html?src=rss
