I enjoy Dr. Gray's explanation very much!

I totally agree with you Ta Yet. Often wondered how they stabilise Hubble, now I know :). Greetings from the UK.

What a great communicator. I could watch her for hours. Thankyou

It's called male gaze. I have it too.

I'd love to see the final picture!

The science that goes into furthering science is incredible! That's one of the most interesting mechanisms in the history of scientific development. It's sometimes an intersection of many different fields. Excellent video!

I could listen to her talking about stars all day long [sigh]

These were some great questions.

I would love to hear more about Dr. Gray's research!

What happened between picture 58 and 59 ? is it because there is this massively bright star that the picture was not taken ? (referring to 4:42 in the video)

Dr Gray needs images with lots of wide ranging data.. I hope this science will always continue.

Is Dr. Gray the best? If she is not, I don't wanna know :3

Brady 'ol lad you continue to educate me

The email about the data now being staged on the ftp host (email at 8:14) also states: "Please retrieve this data as soon as possible, as data are deleted automatically after a few days." I wonder if this ever went wrong. Someone has to have backups...right?

They also said that all pictures will be made available to the general public after a year. To me that implies that the FTP files aren't the only copies ;)

The original data was stored/backed up on other servers/tapes I would assume. The FTP server they were using to let the scientists get the data from was probably a temporary holding location with limited capacity, which would be why they rotated the data in and out quite quickly. They probably also didn't want external access to the main storage servers.

1.5GB of data must have taken ages to transfer 15 years ago.

Only like a 2 CD movie, that was no problem in 2005.

How "honest" - true-to-life - are images of the universe? Are they embellished? If we were to stand somewhere out there, would it look as displayed?

8:14 Waaaa. They use the multipliers for binary prefixes but the symbols of decimal prefixes. And even worse: They seem to think that bits and Bytes are the same thing. Using FTP with a login required on the internet isn't exactly smart either, but I guess the files are stored in a save location so an attacker can't just delete research data from the FTP server before its retrieved and then it's gone. I hope they included checksums further down the email as FTP has a *slight* tendency of corrupting data while transporting it.

The Hubble was *behind* the Earth????

So there is no picture ?

James Webb is going to blow our fucking minds!

Wait.. Hubble only does black and white??

Most telescopes do. The CCD chip has a filter wheel so you can chose different filters. You get one image though a red filter, one image through a green filter, one image through a blue filter and then you lay them on top of each other to make a complete color image.

What if James Webb was to suffer a set-back? There simply must be some kind of contingency, even out there... Am I wrong?

Nope, you are not wrong. Let's hope they won't rely on "creative solutions", because there is only so much that can be improvised. And I know the people in the project KNOW this, but still, can never be too safe with something so far from any sort of maintenance. Our history show that problems that were not imagined WILL happen, so a contingency would be necessary. Unless, of course, funding is the problem. In that case crossing fingers is all one will be able to do... But in that case I'd bet the telescope will have alignment problems of some kind. Or problems with its mirrors. I hope they have a contingency, even if limited.

It depends on the mode of failure. If it is something small, they will likely compensate as best they can and do what science they can as is. But if it was something critical like the heat shielding failing to deploy, it's likely that it would be put into a low power state and simply left alone until we have something capable of fixing it. Remember that even Hubble took 3 years to get a mission up there to correct the lense to it's intended accuracy. Currently, we don't have anything capable of getting humans as far out as JWST is going to be, but if the problem is well known we could design a robotic probe to send out and fix it. That would take several years at least to design and build, but considering the cost and effort that has gone into JWST it's likely that we'd try. JWST actually has docking points for this reason ;)

The fallback is a long, drunken stupor.

I enjoy Dr Gray every time. But why block up time on the James Webb telescope if it's really not the kind of scope you work with, when there are so many others who'll be in line working with the scope that aren't as well known as Dr Gray. Thus probably not going to get chosen simply because of Dr Gray's name. We see this sort of thing all the time...
