Exact same, can’t find the website I looked at yesterday that had the comparison but the new one was unbelievably more detailed and took 7.5 hours to collect the light. The Hubble took something like 14 days to take its picture.

Is the Webb telescope part of Hubble?
Total noob question. The pics are amazing.

No. Two different telescopes.
Hubble is in orbit around the earth.
Webb has a much larger mirror and is a million miles away. It left a note on the fridge saying it "needed some space". Ba-dum-bum.

Yes, different telescopes. I will add that the Hubble scope was designed to primarily observe in the visible and ultraviolet range of the EM spectrum. The James Webb is primarily designed for infrared wavelengths.No. Two different telescopes.

I thought I read 12.5 hours compared to 23 days. We might be referring to different images though. The point is still the same.

For Webb to be able to do the visible spectrum it needs to be about an order of magnitude more precise than the current design. I hope they try that next.

The pictures are mind bottling.

Not sure how that’s possible. If you watch that part of the clip above when they zoom back out you can see uncountable galaxies and that’s just a minute snapshot of one area.
But to be fair- you and I don’t even know what we’re looking at.

Pfft. Seeing things from 13 billion years ago. Meh, no biggie. Who wants to look at old stuff any way, right?

He's an electrical engineer that's got a civilian contract. I think he designed integrated circuits for the telecommunication aspect of the camera.
It's sad to say but I didn't inherit my dad's intellect as to mechanic/physics/science so we really never connected about his work.

I don't think this feed has been linked here yet. It seems to be a live stream looping through pictures from JWT. https://www.youtube.com/watch?v=__xuMe5rLGc&ab_channel=THEREALPAX

Article states 13% of people who were asked about the JWT feel it was/is money ill-spent.
I'm trying to not be too judgy....but geez this is some big time small mindedness going on.
Galileo

Only 13%? Hmm, I would have thought that number would be higher. For the record, I disagree, but still thought the number would be higher.

Footballguy
That's the same % of people that have an unfavorable view of NASA overall (elsewhere in the article).
That means that vast majority of people think it's money well-spent.

Despite claims
JWST doesn't disprove big bang
"Even if we take these rare, large initial fluctuations and let them grow at the maximum allowable rate, it’s very difficult to get enough galaxies that will be massive enough, evolved enough, and that will form early enough to be consistent with JWST’s observations.
This new set of observations presents an exciting challenge for our modern cosmological theories, and an exciting challenge for cosmologists to try and puzzle out. Why do these galaxies have the properties that they do? Can our standard model of cosmology be reconciled with these observations? And if not, what sort of implications does that have for what else we might learn about dark matter, the expanding Universe, or other aspects of our cosmic history? These are all legitimate research questions that people are actively working on right now, at this very moment."

No talk about the first SLS flight going up soon? Could see humans on the moon again in 2 years...

I'll be looking at it up close from KSC
....looking forward to it and hope the sky is cloudless.

Artemis 1 launch this am
Scheduled for 8:30 am et with 2 hour window. Problem with engine #3 may delay the launch. Fuel leak that appeared in Spring test fire has re-emerged.
Currently on hold at T-40 min.

You would have to be a dummy to go up in this first flight.

Today's launch just scrubbed.
Earliest next availability is Sept 2, depending on ability to resolve current issue.
Galileo

There is no crew for this launch. It is just a step in the process of returning to a crewed mission

I think that was the point. The only passengers are instrumented "dummy" humans.

Traffic on the Space Coast in Brevard County is terrible. And I'm assuming that if you came here for a launch today, then you are most likely staying for the rescheduled one on Friday. The hospitality industry in the area is just loving the $ influx. Sucks for us locals though

Next attempt Sat, Sept 3
2 hr launch window starts at 2:13 pm ET. Weather more favorable on Sat over Fri.

Another hydrogen leak this am. Trying to fix seal to continue toward successful launch at 2:15pm today.
