Hey everybody! Sorry I went awol for a little sabbatical from writing. It is summer plus I felt burned out after the last two (or 20) years, and none of my blogging pleasure centers were registering any joy. However today there is something to be quite joyous about: the President of the United States released the first deep field image from the James Webb Space telescope, a colossal near-infrared eye in the sky, which is now unfurled, debugged, and fully operational at Earth’s second LeGrange point! Huzzah!

And what a picture it is. It is so good and so spectacular that it almost looks like background art from a disco album rather than a colossal galaxy-studded expanse of outer space as it existed billions of years ago. The image is a composite of multiple scans taken with the space telescope’s Near-Infrared camera over a 12.5 hour window (the world famous ultra deep field photo from Hubble which rocked the world back in 2004 required closer to 12 days of scope time and did not peer early so deeply into the universe).

The Webb image shows the galaxy cluster SMACS 0723 which is 4.6 billion light years away. Because this galaxy cluster is (or was?) so massive, it acts as a gravitational lens and much more distant galaxies can be glimpsed in the curvy fisheye at the center of this image. I am no galactic astronomy expert (here are some vague pointers about what the color means from an earlier post), but the beauty and grandeur of the image is evident to even the rankest layman…and this is the first real image. There are going to be lots and lots of additional pictures coming in of every conceivable sight out there in the universe and we are going to be blown away by what we see. I can hardly wait for more!
