[@ogshotglass9291]

I may be a bit late, but I have had some questions that the JWST team may be able to provide. First, since Webb was originally designed to complement Hubble, but the project took far longer than expected, and seeing that in recent days Hubble has been having increasing problems, are the two still expected to be working together? And if so, how will they work together and what are the proposed missions going to be focusing on? Second, in the early days of planning, what devices were proposed to be on Webb that were eventually not used, either due to practicality issues or weight reasons? Third and finally, what did the system overhaul in 2016 consist of?

[@rjeff4179]

July sounds great. I hope it all works out. It's an interesting situation. Thank you!

[@charlesackman892]

I would like to thx the ppl involved in the entire Webb team, NASA, ESA, CSA, and everyone else. I have smoked for 51 yrs and have quit because I want to live to see as much as the scope can reveal. Also, on a computer simulation I sort of designed, the design of the mirrors really works well for pumping light into vertical farms.

[@fact-age]

I have 2 questions which I would love to have them answered by the JWST team and I would appreciate if these questions reach them so that they can be answered in the next session of the JWST team press conference. 1. The cooling of the instruments need to be 7 kelvin, I would like to know why this temperature the 7 kelvin was chosen? 2. When commissioning is done and the scientific work commences, we are told that there will be a full year of scientific experiments and observations to be carried out with the JWST, when do we we expect or how long will it take for the first scientific reports to go public?

[@witext]

The MIRI instrument will be chilled to 7 degrees, the NIRCam and the other Near Infra Red instruments don't have to be as cold I'm pretty sure 7 Kelvin was just the best they could do within the weight limitations, it's hard to cool something down more than that I mean the only thing protecting Webb from the scorching sun is 5 ultra thin sheets of sunshielding If you're more interested in this stuff i just wanted to recommend the "where is webb" site, there you can track the temperature of the instruments in both kelvin and farenheit and celsius

[@fact-age]

@@witext Thanks for the answer, so the point is to cool down the MIRI as cold as possible which practically can hardly reach temperatures lower than 7 degrees Kelvin.

[@Markle2k]

@@witext What you said. It's about making sure that the detector's inherent photon emissions is not brighter than the target. The peak wavelength at 7K is 414 μm. MIRI is designed for 4.9 to 28.8 μm, with the imager capable of 5.6 to 25.5 μm. 28.8 μm is the peak wavelength of a blackbody emitter at 100.6K. 4.9 μm is a 591.4K (318 C/605 F) blackbody's peak wavelength. So, at 7K the detector will be very dark compared to its targets. The rest of the instruments are quite near their planned operating temperature of ~40K already. MIRI is still sitting up at 90K because I think they are trying to avoid thermal stress from cooling it too fast. Question #2's answer is: "it depends". There are four classes of observations, those taken in the calibration phase (now) and Director's Discretionary-Early Release Science which will be available immediately. The DD-ERS is intended to demonstrate JWST's capabilities to those who want to write proposals for the coming years so all of it is in the first five months. And then there is Guaranteed Time (for those who donated hardware, etc.) and General Observer which will typically have an embargo of about a year to let the proposers write their papers on the results of the observations. Most of the time is allocated to GO. Some of the GO observations that I looked at seemed to be OKing immediate release of their data. If you go to the Space Telescope Science Institute's web site and then put "/jwst/science-execution/approved-programs" (without the quotes) right after the "edu", it will get you to the lists of approved observations. One thing to note, they have deliberately oversubscribed the first year of observations so some that were approved will not be getting their time in the first year. This is so JWST isn't sitting twiddling its virtual thumbs or slewing across the sky between observations, something that they learned to do after the first year of Hubble when a lot of potential observing time was idle.

[@witext]

@@fact-age Yeah, space itself has a temperature believe it or not, at about 3 kelvin, so that's the coolest webb theoretically could get. And then you have to account for the small amount of solar heat that gets through the shield Also the machinery and batteries and all the things that keep webb running also produce small amounts of heat When you've taken all that into account 7 kelvin is basically as cool as it can get

Hey, if the JWST had a twin in space like a stereo set of eyes, how much would it increase its accuracy/clarity/magnification power, and how far back in time could it see? Also are you folks ever gonna aim it at the Earth to see what an alien civilization on another planet might look like, but fainter, so you could use it to basically make a fainter "prism spectroscope" like image of our emissions and planet features as an idea of what to look for on exoplanets?

I wonder if dust and small particles get stuck in the mirrors surface, would that degrade the optical perfomance?

[@alph4096]

The mirror's surface was cleaned with liquid carbon dioxide in a strictly air-conditioned clean room. Of course, if human eyelashes or dust adhere to the surface, the optical performance will deteriorate.

[@zounds010]

Yes. fortunately, space is very empty: JWST will encounter micrograms of dust per year, on average.

[@Markle2k]

Not nearly as much as you might think. The area obscured is much less than the overall area. This came up as a question about the impact of a micrometeorite hit to the mirror on the optical performance. The big Earth-based telescopes spend thousands of hours a year exposed to dust. They only really clean them every few years. Every few weeks, they essentially blast them with a CO2 fire extinguisher and let the solid CO2 lift the dust grains free of the surface.

[@gorgejack5153]

Was Mr Eileen Fineberg fart 5:25 min into the discussion part of the Webb mission?

[@NeonsStyleHD]

Question: Since the physics of Diffraction are so well known. Why can't you write a piece of software to subtract that from the image after stacking?

[@Myndale]

This is often done, but you lose contrast and valuable scientific data, so you generally don't want to do it for images used for research purposes. Another technique is to take multiple images of the same target at different rotations and stack them. The reason the spikes are so prominent in this image is because HD 84406 is heavily overexposed...remember, this is just an initial calibration image of an object far brighter than most of the things JWST will be looking at. There's a really good video at kzbin.info/www/bejne/i3PGlGaspa-Hd7c that explains a lot of this in detail.

[@SAAssef]

Hi! How are you guys?? Any news? What are you looking at?

[@ericpmoss]

If the whole thing moves to point at a target, how does the sunshade stay between the sun and the scope+instruments? Does it mean that it can only work within a narrow wedge of the sky?

[@kylej7593]

it does have a specific angular area it can observe in, because you are correct, but it’s not as narrow as you would think. throughout the year though, it does have access to all the areas in the sky because of its rotation around the sun.

[@beta_cygni1950]

It has limited field of view at any single time. But as it orbits around the sun, it has access to the entire sky. So to view a particular object, JWST might need to wait several months until its orbit aligns with the object.

[@zounds010]

They can change the sunshield angle between about -5º and +30º, so at any point they can image a cylinder of the sky about 35º wide.

JWST is IR only. NIRCam works in near-IR and MIRI works in mid-infrared.

distance and age are linked by the speed of light. When you look at something one light-year away, you see light that left that object one year ago. So you see the object as it was one year ago. This applies to any distance. So when we look at objects that are 13.5 billion light-years away, we inevitably see them as they were 13.5 bn years ago.

I keep wondering how fragile the JWST is? Could any small meteorite knock it to pieces? Or at least way out of alignment?

[@beta_cygni1950]

I wouldn't worry about that. First, there just isnt much debris at all. Its not like in earth orbit, where earth has attracted all sorts of junk. Remember... There are / have been other probes at L2 (some of them have been there for 10 years, and some way longer than that). And not one of them has ever ran into an issue. Secondly... The sunsheild is the largest target on it. And it was designed to keep from shredding should anything puncture it. Third... Over time there WILL be small potmarks in the mirrors. These won't degrade the images. Optics just don't work that way. For example, my old 10" reflector has several mirror chips and stuff. They don't affect the image at all. Any single imperfection only represents a tiny fraction of the overall area & they average out & smooth over. So its not a big deal.
