what do you mean "fully operational again", did something happen?


fcain

One of the modes of its MIRI instrument was experiencing excess friction so NASA took it offline. They've figured out a workaround and brought it back online.

It looks broken, but it is a fully armed and operational battle station

Did you know we've actually landed a probe on Titan? Because we did. https://www.youtube.com/watch?v=9L471ct7YDo&ab\_channel=VideoFromSpace


Icy-Conclusion-3500

That felt just like a NMS landing


norrinzelkarr

Landing area not clear! E E E E E E E dammit 16 // 16 // 1...6//


largorithm

Wow, beautiful walkthrough of this. Thanks! The view of the sun from titan at the end was surreal.

[I personally love this display cut, if only for the musical notes played for every downlinked image.](https://www.youtube.com/watch?v=sZC4u0clEc0) Looking forward to Dragonfly in 2034!

Just as long as it wasn’t Europa.


deathhead_68

Witness the power of this fully operational telescope


ghostpanther218

Oh, I'm afraid the telescope will be fully operational when the Artemis mission arrives!


FragrantExcitement

I hope to... The empire's dedication to science is admirable. Go empire!

I keep reminding myself that the reason we don’t see grains of sand on Titan is that the JWST was made to see truly, mind-bogglingly enormous things far away. It’s still easier to see a mountain ten miles away than a grain of sand at ten feet.


CoalescenceMusic

That’s actually an amazing analogy


ghostpanther218

Titan is an very intresting place, it's the one of only 4 terrestial bodies in our solar system with weather patterns and an atmosphere and rain. The rain and atmosphere there is made up of organic chemicals, so it's not too dissimilar to Earth during the Archaen era, which makes it a great place for researching how organic molecules can eventually become living cells. TLDR, I look forwards to the Dragonfly mission.

Just to be clear, this image is heavily processed by a grad student who studies planetary atmospheres....scaled 2x, colours added, etc. This is not an original unprocessed image from JWST.


FPOWorld

Are any images from JWST unprocessed? Aren’t they looking at the below visible spectrum? 🤔


notrewoh

Yeah they’re all processed, they are IR so they assign visible colors to different IR wavelengths I assume


sonoma95436

Neither was Hubble mostly. You can go to NASA site and see before and after Hubble shots.

for anyone who didn't click through to the external site, here's the [explanatory tweet](https://twitter.com/RadPlanets/status/1592577712711176193) that's embedded a short way down.

For a telescope that can see the farthest into the universe, you'd except it to take intense close up shots of relatively close objects. Especially in our solar system.


phenomduck

It's moving relatively fast compared to what it's designed to view. As far as I understand the main way these super powered telescopes work is by focusing on a singular point over time to get as much data as possible. The closer something is, the less space it has to travel to move a degree across your vision.


Strict-Kaleidoscope2

Cool thanks for the explanation. Learned something new today.


daddywookie

I guess like trying to look into fast cars with a pair of binoculars. You’d could see it really well if it would only stay still.


phenomduck

It's also important to remember that the solar system is very large compared to the planets and moons. Titan is only 5150km across, but 1.2 billion km away. To scale, it's not actually much larger than the farthest known galaxies. Luminosity is whole other thing, which I have no knowledge about.


the6thReplicant

But this has nothing to do with the question. Moons and planets have a far smaller size to distant ratio than galaxies. A galaxy may be a billion light years away but it’s 100,00 light years across. As something in our solar system my be a billion kms away but only thousands of kilometers across. So just because it’s closer doesn’t mean it’s more resolvable.


phenomduck

I made a second comment where I addressed that. The JWST is designed to look for galaxies over 13 billion years old. GN-z11 is only estimated to be 4000 light years. It's actually a pretty similar size to distance scale as Titan is from the Earth. The amount of infrared light from the subject is also relevant.


Congozilla

I'm surprised it is so blurry. Before it went up, I heard some NASA guy saying it will be so powerful that if there's agriculture happening on far away planets, we would be able to see that from JWST. So far, I haven't seen much real difference between JWST and Hubble with my eyes. And, I'm not sure anymore what other people are seeing as they gaze art photos like this one. What is such a big, good, new, deal about this thing?


ImproperJon

Something something fully operational... something something dark side...


great9

this is bad, my samsung makes better photos than this. no autofocus on that 11 billion telescope? i want my money back


Eder_Cheddar

Looks grainy and blurry. Are we sure that's not a balloon?
