some black hole work analysis in stephan's quintet.

mid infrared image from the quintet.

 

the supermassive black hole at the top got the spectroscopy treatment both right in the middle and the gas around it.  closer to the middle, the less elemental diversity and just molecular hydrogen and various silicates.

 

breakdown of the hydrogen.

from the original image, one of the more distant objects that was resolved had a redshift indicating a distance of 13.1 billion light years. 

Assuming there’s an equally far/old object in the opposite direction from us, that means there are objects at least 26B light years apart, right?  How did the universe get so large in only ~14B years? That seems to imply relative speeds greater than the speed of light.  This stuff might be too hard for me to understand.

correct...for context, space shuttles orbiting earth have a velocity of about 17,800 mph.

what you are asking is actually quite complicated...and has a lot to do with why this guy is a household name. 

it is very difficult to wrap our brains around it but when you consider concepts of 13.1 billion light years, you have to think of things not in terms of just distance/size but also in terms of time.  you have to remember that what you are looking at is 13 billion years ago and not reflective of where it actually is.  and things start getting really funny and you start getting into einstein's cosmological constant which then evolves ultimately into accelerating and inflationary dark energy causing expansion at greater than the speed of light.  you also have to wrap your head around the concept of large scale structures such as the observable universe and the fact that there is a limit to observable signals.  stuff that is impossible to understand through message boards.

if interested, start with the cosmic microwave background.

then large scale structures.

ultimately, we believe the observable universe at this point has a radius of approximately 46.5 billion light years of DISTANCE...but don't conflate that with time.

If it were up to me I would spend the entire nasa budget on telescopes and sending rovers to planets & moons.  Looking at these pictures never gets old.  It's ancient transcendent universe art.

Indeed. Sadly the entire budget for NASA is $25 billion this year.

Agreed.  There are 200 billion trillion stars.  It would be unbelievably far fetched for exactly one of those to have spawned a planet with life on an evolutionary scale.

[Hermanator 7,042]

The spectrometry aspect is really intriguing. Over time if they can isolate some rocky worlds and catch them with elevated levels of stuff like oxygen and nitrogen it really points to high probabilities of life. Get lucky and catch signatures of fluorocarbon and we're staring at intelligence.

It's mathematically impossible at this point...and really within our own galaxy this is true.

So what kind of image could we expect if we point this baby at Proxima Centauri? The first thing I would be doing if I was in charge of this giant reverse space laser is trying to see what kind of information I could gather on the planets orbiting our nearest stars.

Can this thing image close-up stars too?  They could take a look at what happened to Alpha Centauri like 4.5 years ago.

an image of our neighboring stars will not be terribly exciting...even with jwst.  it won't look terribly different than the hubble image below.  they will just look like super bright dots.  from an "imaging" perspective, the exciting use of jwst is looking deeper and deeper into space/time, not so much the local area.

however, the extreme jump forward in the sensitivity of the measurement tools is going to give us a ton of more scientific insight into what's going on next door.  for example, there are tons of observations on the proxima centauri a, b, c, and d exoplanets but we still know very little about what's actually going on there.  researchers have theorized that proxima b has potential for an earth like planet in a habitable zone orbit that could have water.  but proxima centauri is a tiny star (even relative to our sun - it's a red dwarf) and has a ton of intense flares so we have no idea if b has an atmosphere that has been blown to shreds by intense electromagnetic flares.  b is 5% as far away from the proxima centauri star as we are from the sun but given the relative weakness of the star, it might be earth like...despite likely being in tidal lock.  if it has water, we have no idea beyond just theories based on previous observation and measurement.  that is going to change with jwst.  once the AC/PC researchers get their crack at some jswt time, we are going to learn everything we want to know about those four exoplanets around PC.  

the imagery is certainly sexier and more effective at capturing the imagination of the public...but when they point jwst at the AC system, it won't be for imagery.  it will be for so much more.

despite the efforts of our more addlepated representatives and the impeding dipshittery that will not sarcastically follow, if you want to understand why jwst has six diffraction spikes and hubble has four, this dude did a pretty deep dive on it.

A test of Webb's tracking systems yielded this image of Jupiter:

Per a NASA presser, the image was taken during the testing buildup prior to last Tuesday's image releases. Webb utilized its NIRCam (near-infrared?) instrument's short-wavelength filter to highlight the planet's bands and Great Red Spot.
