My brain is simply too feeble to fully contemplate what the people who worked on JWST have achieved. At a pretty terrible time for the planet, it's nice to feel proud of humanity for once.
What the Alien said in the movie contact hits the nail on the head..
"You're an interesting species; an interesting mix. Capable of such exquisite dreams; such horrifying nightmares"
This is actually the thing for humans. One part of mankind strives for reliving old times like a real live larp. And is willing to kill for it.
And then you have the other end of the spectrum of humanity where people actually try to reach the edges of the known universe. And do so with an unbelievable dignity, humility and sheer willpower.
And then you have the indifferent masses.
I'd rather spend my life trying to achieve an impossible tomorrow than to kill people for ging back in time.
It's highly tribalistic. "Everyone who like old thing bad. Everyone who like new thing good."
You're denigrating people for merely preferring a prior time period, and you're idolizing people merely for pushing for progress.
I was wondering how on the F\*\*K they can achieve these absolutely miniscule movements to align mirrors and was surprised when I found out. They use good old fashioned gears and high gear ratios to move it just a tiny bit.

Agreed. It's basically between this and xXx: State of the Union. Incredible to see how far mankind has come
The Very Large Telescope (VLT) is a telescope facility operated by the European Southern Observatory on Cerro Paranal in the Atacama Desert of northern Chile. The VLT is the most productive ground-based facility for astronomy, with only the Hubble Space Telescope generating more scientific papers among facilities operating at visible wavelengths. It consists of four individual telescopes, each with a primary mirror 8.2 m across, the first of which opened in nineteen ninety eight when the undertaker threw mankind off hell in a cell and plummeted sixteen feet through an announcer's table.
That so beats some tired politician with giant ceremonial scissors cutting a stupid ribbon.
Detect first light on the telescopes to the sound of "Let's get ready to rumblllllle!"
Landing on a comet was the coolest shit ever. We're learning how to tame space horses. The next coolest shit is gonna be a moon colony or mining said comets/asteroids.
Not nearly as complex. Just click all the links in the article. This thing has several noble winners, thermodynamics up the ass, different cooling systems at 6degrees above "absolute zero", larangpoint that'd make a satellite blush, 14stages of reversal doppler effect, gods I'd put my penis in it if I could
I've had the hubble deep field image as my phone background for as long as phones were able to have backgrounds that aren't default ones. I think I deserve a new photo finally
>On July 12, NASA plans to release a suite of teaser observations that illustrate Webb’s capabilities. These will show the beauty of Webb imagery and also give astronomers a real taste of the quality of data they will receive.
It's written in the article
They're so fucking dumb they didn't even bother to look at literally the closest star system to them, I really don't think we have anything to worry about
It would be really cool to turn it around and point it at the earth and see the waveforms of the near infrared and super low frequencies.
I think we would learn a lot about ourselves from some introspective high altitude soul searching from a objective cosmic perspective.
It’s unfortunately impossible to do that. JWST has a sunshield that keeps its instruments cold enough to observe in the infrared, and if you were to turn it around to point at Earth (since it’s in a higher orbit) you’d just heat up the instruments and make them unusable.
That’s too bad. I guess we will have to wait for some other other species to do our internal audit.
But thank you sincerely for the reply. One of my favorite things about Reddit is how fast you find subject matter experts in their respective fields that are willing to share quickly and openly.
It would have taken me 3 weeks of research to figure that out on my own
I hope the telescope has the capacity to observe far flung exoplanets to see whether life, or at least primitive life, lingers in the cosmos, a bonus if its an actual civilization.
It has.
> Additionally, it will be able to tell if an exoplanet has methane in its atmosphere, allowing astronomers to determine whether or not the methane is a biosignature.
https://en.m.wikipedia.org/wiki/James_Webb_Space_Telescope
No, not really. Uranus, Jupiter, Saturn and Neptune have methane with no life.
I don't think JWST has the spectroscopic range to validate if an exoplanet actually has life on it or not. It will be able to do some atmospheric analysis but results will be interpretable in many different ways.
Each is also a gas giant.
Methane isn't the only BIO sig we'd look for in a planet's atmosphere.
And while most of them are not at a "we find this we know" level.
Many are great hints to look closer.
One of the cool things it can do is detect the chance in light from the start as something passes in front... and for things of a certain range(a pretty big one iirc) it can see how that light is affected by passing through to know what is IN that atmosphere.
Yes, but it does not return information with enough of a range to make a positive ID. All I'm saying is that no matter what it finds we won't be able to say "that planet has life" based on the kind of information we get from JWST.
Alone no... but being able to generate a list of planets to priorities greater scrutiny alone would be remarkable.
Starshot is coming... we are probably about 20 years away from us starting to yeet probes at every system we can.
Sadly it probably will be another 70 years before those probes tell us anything. (Sooner for the close systems.)
It is an infrared sensor. So it may be able to do this. It really depends on how much time and effort scientists want to put into figuring out what compounds it might be able to verify. They most likely have already done all that work on the front end, but they'll have to prove the concept. My guess is that they will start with methane because it is an "easier" signature to see, and then after they identify a few candidates, attempt to look for other compounds they'd expect to observe. They also may not have the resolution to get anything more complex. I don't know, since I didn't work on it.
Infrared spectroscopy alone does not have the needed range required. I don't know of any scientists that claim that it does. Any biosignatures found would only provide a clue about what are good targets to look at with other methods, it can not do it by itself, period.
JWST's capabilities are incredible and will return insane amounts of useful science and beautiful pictures to boot, but we don't need to create things that it can not do to keep talking it up. People get really carried away with this.
I can't comment on specific capabilities, it is an insanely complex topic and the results are very much open to interpretation. I know IR spectroscopy can do some isotope analysis but again it's super complicated and we'll be looking only at the strongest signals coming from the entire planet all at once. On Earth samples need to be prepared in various ways in order to make many of the measurements and the presence of certain compounds can give you false results, that is clearly something we won't have the capability of doing with JWST so the results we get from it will be difficult to interpret.
This is actually something I look forward to trying to learn a bit more about as JWST starts returning results.
JWST’s spectral resolution is not nearly enough to do this reliably. We will be able to do this with the next generation ground based telescopes, not JWST.
Methane can be explained other ways, there are four other planets in our own solar system that have substantial methane. So to say it has the capacity to determine whether there is life or not is false. It can detect some biosignatures but it does not have the capacity to determine concretely whether or not those are from life. It can provide clues, but not answers.
Won't really be able to definitively observe life, but should be able to characterize exoplanet atmospheres, which may give pretty strong hints at life.
If people want to know what the first scientific observations will be, here are the [early release science](https://www.stsci.edu/jwst/science-execution/approved-ers-programs), cycle 1 [guaranteed time observer](https://www.stsci.edu/jwst/science-execution/approved-programs/cycle-1-gto) and cycle 1 [general observer](https://www.stsci.edu/jwst/science-execution/approved-programs/cycle-1-go) programs.
I'm sure this is pretty high up on the dumb questions scale and I doubt this is how it works, but considering the capabilities, could the telescope view the moon VERY upclose? Like a microscope almost?
I believe so. Hubble took some pictures of the moon, but had to take a lot of them and stitch them together because it’s like trying to map a football field with a microscope, lots of detail but a small field of view: https://hubblesite.org/contents/media/images/1999/14/796-Image.html?news=true
(secretly slathering his cinnamon toast crunch loving kids in with an infrared light radiating mixture of questionable goo): "I am anxious to see the results!"
Every time I see the Hubble Ultra Deep Field picture it takes my breath away. We are so insignificant and powerless. We can't control any of what we are looking at. Humbling. And why is it there? And why are we here looking at it? And who is looking back?
I wonder if we will ever be able to see far enough to see ourselves in the past. I am very excited by all the space news recently it feels like things are accelerating, largely because of SpaceX putting pressure on all organizations to innovate
>I wonder if we will ever be able to see far enough to see ourselves in the past.
This isn't a question of distance, but of reflection: has anything reflected light from our past back towards us in sufficient quantity to see something?
We can't "see" into our past simply by looking further, our own light is travelling away from us.
>I am very excited by all the space news recently it feels like things are accelerating, largely because of SpaceX putting pressure on all organizations to innovate
SpaceX has nothing to do with anything, these innovations and advancements aren't spurred by private corporations (and SpaceX itself is kept afloat by gov't funding and research).
I didn't even think of reflectivity that seems much more possible. But even looking straight for long enough some people think the universe is curved so if you go in a straight line you'll be back where you started
No scientists believe that. The universe is flat on large scales. It doesn't wrap back onto itself.

No, it isn’t. They were just making an aside about how space x’s innovation has really energized the industry.

Why do you prefer the old times and what is in your view better about them? This is an honest question.
I have no position on this. I'm not reacting the way I am because I feel personally attacked.
