"French scientist Etienne Klein apologises after 'James Webb Telescope' image revealed as slice of chorizo" | ABC

QuoteA senior French scientist has apologised after tweeting a picture which he said was from the James Webb Space Telescope — but which was not quite what it seemed.

Etienne Klein, a director at France's Atomic Energy Commission, posted a picture purportedly showing Proxima Centauri, the closest star to our sun.

"This level of detail ... a new world is revealed every day", he enthused in the tweet, sent to more than 90,000 followers on Monday.

However, Professor Klein has now admitted that the glowing celestial body shown was in fact nothing more than a slice of Spanish chorizo sausage.

[. . .]

Apologising for what he described as "a scientist's joke", he said his aim had been to remind people to "be wary of arguments from people in positions of authority".

"I come to present my apologies to those who may have been shocked by my prank, which had nothing original about it," he tweeted.

Proxima Centauri, the closest star to our sun? Or...

...A slice of Spanish chorizo sausage?

Answer: Both are alternative facts.

Truth:
A slice of a, "4D sausage along the time axis."

A slice across time and the plane of the telescope's field of view. :smilenod:

Got it.

See?
I pay attention.

...Also, should never, ever apologize on Twitter. That place has honed clutching onto any perceived offence and never letting go to an art. A misplaced apology there is likely to have an person up to their neck in sins to repent, and repent immediately and to the mob's satisfaction. Except of course there is no satisfying the mob.

Me, I just tend to get banned from there. With a smile - every time.

I watched a Nova (PBS) program about the construction and testing of the JWST.  Fascinating stuff to be sure.  The scientists and engineers were extremely careful about every conceivable detail.  They compiled a list of 334 possible failures that could doom the whole 20+ yearlong project.  They systematically addressed every one of the failure possibilities. That is one of the reasons the project took so long to complete. 

The whole machine was shipped to Houston so that it could be tested in a vacuum chamber whose temperatures could be reduced to more than minus 200 centigrade.  It took 30 days to gradually draw the temp down in the chamber. The Telescope endured the temperatures well enough, then they did the vibration test where the macie was exposed to the vibrations expected during launch and flight in space. An unexpected glitch was revealed.  During vibration tests some bolts and nuts fell off which might endanger the sucess of the whole thing. One more of the failure possibilities was revealed and remedied.

Among the biggest dramas was when the machine was in place and had its heat shields deployed, That was a delicate process that took several days.  After that, the had to adjust each of the mirror leaves so as to focus correctly. All that done while a million miles away.

The whole project was a mind-boggling, spectacular effort on the part of the builders and operators. That is one helluva expensive bit of work. Billions and Billions of dollars were used in the process. At one time congress almost shut the whole thing down because of the enormous expense. Fortunately, they did not cut off the funding.
