Galaxy's detected at nearly 97% of the way back to the Big Bang:
The massive gravity of galaxy cluster MACS0647 acts as a cosmic lens to bend and magnify light from the more distant MACS0647-JD system. It also triply lensed the JD system, causing its image to appear in three separate locations. These images, which are highlighted with white boxes, are marked JD1, JD2, and JD3; zoomed-in views are shown in the panels at right. In this image from Webb’s Near Infrared Camera (NIRCam) instrument, blue was assigned to wavelengths of 1.15 and 1.5 microns (F115W, F150W), green to wavelengths of 2.0 and 2.77 microns (F200W, F277W) and red to wavelengths of 3.65 and 4.44 microns (F365W, F444W).

Imaging two separate structures was a surprise since Hubble displayed only one galaxy. Mankind's ability to perform research about the evolution of galaxies in time has gained a lot of traction since the James Webb telescope was finally deployed.
"Every single one of them. It's amazing the amount of information that we're getting that we just weren't able to see before. And this is not a deep field. This is not a long exposure. We haven't even really tried to use this telescope to look at one spot for a long time. This is just the beginning."

Mercury's sodium tail:
"Mercury's thin atmosphere contains small amounts of sodium that glow when excited by light from the Sun.
Sunlight also liberates these atoms from Mercury's surface and pushes them away. The yellow glow from
sodium, in particular, is relatively bright."

^That^ is an exploration understatement.
Sending a number of robotic drills stuffed with a set of robust diagnostics* to discover what is underneath the water ice would be wonderful.
________
* A miniature submarine fleet in contact with surface drills and transmission antennae systems - perhaps

The Sombrero Galaxy - an infrared image
This galaxy's classification is unclear based on it's appearance 31.1 million light-years from our Milky Way Galaxy, and its diameter is about 49,000 light-years in diameter. It resides in the Virgo supercluster.
