Do we get spectroscopy from these images? What are the chances we could get detailed information about the atmospheres of earth-like exoplanets at some point in the future?

https://en.wikipedia.org/wiki/TYC_8998-760-1 cites a paper with spectroscopy results.

TYC 8998-760-1 b is a gas giant exoplanet which has a mass 14 times that of Jupiter, and a radius of 3 RJ. It orbits at a distance of 162 AU (2.42×1010 km; 1.51×1010 mi), or slightly more than 5 times the Neptune-Sun distance.[5][7] In July 2021, astronomers reported the detection, for the first time, of an isotope in the atmosphere of an exoplanet; more specifically, the isotope Carbon-13 (C13) was found in the atmosphere.[8][9]

Though it's not Earth-like, we have already got some data on exoplanets using spectroscopy.

Amazing. Can't wait to see what the James Webb launch is going to show us.

I wonder how they prioritize time? There's going to be a huge backlog of people wanting to re-image everything, the decision making procedure must be stressful.

First round has already been awarded: https://www.stsci.edu/jwst/science-execution/approved-progra...

Indeed, they must know already what will be imaged first. It would make sense to look at something Hubble has already studied in detail - both for calibration but also to understand the differences in the data outputs. So it might be an updated version of an iconic Hubble shot. It would be a nice victory lap for the team to see those comparisons.

I'm nervous just thinking about getting to that first operation and the crazy set of steps that need to be perfect on the way.

After the VLT comes the ELT. I wonder what superlatives will need to be used for other future telescopes.

The OWT was proposed, but not funded. Yet.

"Overwhelmingly Large Telescope": https://en.m.wikipedia.org/wiki/Overwhelmingly_Large_Telesco...

The GBT monster, the king of the telescopes at the Green Bank Observatory in West Virginia -- I always think of it as the "Great Big Telescope": https://en.m.wikipedia.org/wiki/Green_Bank_Telescope

A radio telescopes, sure, like the Very Large Array... but the next such instrument up is simply the "Square Kilometer Array", reflecting (!) the total area of all if the array elements.

(I lobbied for naming it the SRSLY, but these international consortiums can be a tough audience to calibrate; they were sick of me by the end of the conference.)

SRSLY isn't as far of an outlier as any of the other names. What was your name spelled out meant to be?

We need Douglas Adams to name a few of these.

BFT 9000?

I wonder if they’re looking back.

Naive question here, but how much more resolution can we ever expect to get out of pictures like these? If it gets 100 times better will we be able see what the planets look like?
