The URL points to thumbnail version of the image (985x1005). It seems that full image is available here: <a href="https:&#x2F;&#x2F;www.nasa.gov&#x2F;sites&#x2F;default&#x2F;files&#x2F;thumbnails&#x2F;image&#x2F;main_image_deep_field_smacs0723-5mb.jpg" rel="nofollow">https:&#x2F;&#x2F;www.nasa.gov&#x2F;sites&#x2F;default&#x2F;files&#x2F;thumbnails&#x2F;image&#x2F;ma...</a> (2799x2856). I can&#x27;t edit the link, so maybe some of the admins can do that.<p>Update: Hi resolution image also available here <a href="https:&#x2F;&#x2F;esawebb.org&#x2F;media&#x2F;archives&#x2F;images&#x2F;original&#x2F;webb-first-deep-field.tif" rel="nofollow">https:&#x2F;&#x2F;esawebb.org&#x2F;media&#x2F;archives&#x2F;images&#x2F;original&#x2F;webb-firs...</a> (4537x4630, ~39MB)

For comparison, here&#x27;s a view of SMACS 0723 from Hubble:<p><a href="https:&#x2F;&#x2F;bigthink.com&#x2F;wp-content&#x2F;uploads&#x2F;2022&#x2F;07&#x2F;smacs0723-73.jpg" rel="nofollow">https:&#x2F;&#x2F;bigthink.com&#x2F;wp-content&#x2F;uploads&#x2F;2022&#x2F;07&#x2F;smacs0723-73...</a><p>&gt; This image of galaxy cluster SMACS 0723 has been constructed from blue, green, and red filters aboard Hubble, along with four infrared filter views of the cluster’s central regions. Hubble viewed this object to wavelengths of ~1600 nanometers; [1]<p>[1] <a href="https:&#x2F;&#x2F;bigthink.com&#x2F;starts-with-a-bang&#x2F;universe-before-jwst&#x2F;" rel="nofollow">https:&#x2F;&#x2F;bigthink.com&#x2F;starts-with-a-bang&#x2F;universe-before-jwst...</a>

Since I&#x27;m a complete noob at astronomy, I wanted to ask a couple of basic questions about the image:<p>1. What causes the bright flares&#x2F;flashes around some bright starts&#x2F;galaxies?<p>2. What are the elongated traces that look as if the telescope moved&#x2F;rotated while capturing the image?<p>3. Why do some of the smaller flares seem to be doubled (e.g. 3 stars in the top-right corner of the image)?<p>Thanks in advance to anybody patient enough to explain.

We’ve come a long way since Einstein ́s Eclipse in 1919 when it comes to observing gravitational lensing.<p><a href="https:&#x2F;&#x2F;www.discovermagazine.com&#x2F;the-sciences&#x2F;how-the-1919-solar-eclipse-made-einstein-the-worlds-most-famous-scientist?ref=hvper.com" rel="nofollow">https:&#x2F;&#x2F;www.discovermagazine.com&#x2F;the-sciences&#x2F;how-the-1919-s...</a>
