That good to know, thanks. If Messier 87 is 54 million LY away, what does that make the field of view in degrees?B... image in post 47 is a composite that measures 1000 LY x 500 LY just to give a sense of scale.
EDIT: 0.002 degree?
Field of view: 6.92 x 7.00 arcminutes.. . . what does that make the field of view in degrees?
N.B. 1arcminute = 0.0166667 degrees. I'll let you do the mathematics!
Indeed, this picture tells a story “Holy smokes, it really worked” . At 27 I was still trying to “master” aligning the phono cartridge on a Dual turntable - and they came with an almost foolproof jig.
It's such a great photo that is the drug of so many of us research types (and I'm sure anyone whose career requires years of work for what seems like a tiny result feels the same). Reminds me when my buddy and I fired up an IC we fabricated (I had so many problems with the process) and watched it perform beyond expectations. That preceded the ubiquity of cell phone cameras, but if my colleague had a shot it'd look a bit like this, except me laying on the floor with my fist in the air.
But let's not let my little story compare to the innovation she (and whom she worked with) brought on. Image reconstruction from sparse data is a HARD_PROBLEM; huge kudos.
P.S. I wouldn't let science deniers ruin this event, or, well, any other such achievement. It's a background noise to something so much bigger.

Apparently the data required "sneaker net" a mass of hard drives that had to be shipped to a central location.

I once tried to convince a man in a bar that a fish was an animal.
He was vehement in his conviction that it was not, and could not
be persuaded otherwise!
So then was it vegetable or mineral?

Come to think of it, fungi may be in a different kingdom.

No, totally wrong.I reckon that the image they have published is a temperature profile recorded as an RF map and then converted to color for viewing by those outside the scientific community.
They asked the software to visualize the frosting.
There's a fixture to do that? I missed the memo.Indeed, this picture tells a story “Holy smokes, it really worked” . At 27 I was still trying to “master” aligning the phono cartridge on a Dual turntable - and they came with an almost foolproof jig.

Nowhere near as accurate or versatile as something like the Denessen, et al jigs, but as I recall they came free with each table.

Here in Maine, folks are arguing that rock-weed (looks like sea-weed) is "more animal than plant". That would change which department and tradition regulates rock-weed harvesting. Unlike many places, in Maine the land-owner must give permission to harvest from the inter-tidal zone, but fish may be taken unless specifically posted (I am not a Maine lawyer-- get a paid opinion before you harvest/fish).
The argument is that rock-weed is "free-living" in youth, floating around the gulf, and then picks a place to put down roots near shore.
The DNA, and the chlorophyll, are not likely to sway the thinking.

The best observatories are VERY far from a StarBucks WiFi, being most of a mile up and many miles from any large town. At just 100' up and 5 miles from a town, I would not attempt to pipe huge datasets; some days the DIYA photos choke my wire. Yeah, bringing drives down from the mountain at least to a large university makes sense. Bringing them all to one table seems odd; maybe the price of cooperation was getting all the workers together for meet-and-greet.

If you use the Dennesson on a Dual TT you will find their template wrong.
Most integrated tables of that time were.
Dave, that's actually a shot of the 4:20 light up last year, here in the 'big smoke', unrelated to this thread.
