It is just about Noon time on this Thursday, March 10, 2022 and I bring to you the very latest images from NASA/the James Webb Space Telescope, my Brothers and Sisters...
Each image is absolutely astonishing to say the least and the superb level of detail that the JWST provides is, in itself, truly amazing given the vast distances involved!
I know I say it all the time, but in order to appreciate the images being shown, one needs to WATCH THIS VIDEO ON THE LARGEST SCREEN YOU HAVE AVAILABLE TO YOU!!!
There is a measurement used here that is interesting and it is called an "Arcminute" which identifies the field of view from the JWST! This is a bit over my head, but thought it worth sharing as it defines the angle/arc of what the field of vision is for the JWST's cameras. Feel free to skip over the below data...
"A minute of arc, arcminute (arcmin), arc minute, or minute arc, denoted by the symbol ′, is a unit of angular measurement equal to
1/60 of one degree.[1] Since one degree is 1/360 of a turn (or complete rotation), one minute of arc is 1/21600 of a turn. The nautical mile (nmi) was originally defined as a minute of latitude on a spherical Earth, so the actual Earth circumference is very near 21600 nmi. A minute of arc is π/10800 of a radian.
A second of arc, arcsecond (arcsec), or arc second, denoted by the symbol ″,[2] is 1/60 of an arcminute, 1/3600 of a degree,[1] 1/1296000 of a turn, and π/648000 (about 1/206181.8) of a radian.
These units originated in Babylonian astronomy as sexagesimal subdivisions of the degree; they are used in fields that involve very small angles, such as astronomy, optometry, ophthalmology, optics, navigation, land surveying, and marksmanship." - This is scientific information from Wikipedia!
Only a little over 5,000 views have been made so far of this particular video, so if you watch it, you will certainly be one of the first 10,000 people to have seen it!

Sgt (Join to see) I was most impressed with image 7. When I first saw it, I thought I was looking at our galaxy, but thought that would not be possible. When the text came up, it said that image 7 is very much like our own Milky Way Galaxy. So maybe I am learning a bit.

Most galaxies are barred spiral ones so those types of galaxies match or own Milky Way Galaxy in looks... Yep! Me thinks your learning quite a great deal, CWO3 Dennis M.!
