Webb Space Telescope

Now that it's unfurling, has anyone noticed the Webb Space Telescope looks similar to …

An Imperial Class II Destroyer?

Since when was NASA taken over by Area 51?

Did you have a look at the video I posted in #3? In that clip they are building a model of the telescope, along with commentary from a NASA scientist.

Yes, I saw it. I still maintain that the so-called James Webb Space Telescope is really an Imperial Death Star, version 1.0

Now that's an upgrade from the previous "Imperial Class II Destroyer" that you never wrote about in the first place!

Imagine what overpriced wiring this telescope is sporting!

According to Space.com, the JWST has passed the orbit of the moon, as of this morning. Sunshield deployment has begun.

So where is the final destination?

So where is the final destination?

Orbiting L2, about 1,000,000 mi away.

Explained: Where is James Webb Telescope going and why do we need to send it so far away

Unlike the Hubble space telescope, the James Webb telescope will not orbit the Earth, it is headed to a location known as the second Lagrange point.

ryanosaur, thanks for your contributing posts. You have good taste in speakers and good taste in telescopes.

Exciting...
The Sunshield has successfully been extended on both sides.
Tomorrow will begin a two day process of separating and tensioning the layers of the shield.

Where Is Webb? NASA/Webb

'WhereIsWebb' shows the status of Webb on its journey to L2 orbit. The page constantly updates as Webb travels, deploys, and cools to operating temperature. The most recently completed deployment step for Webb is displayed along a timeline that also indicates the major deployment phases. Note...

The secondary mirror has been deployed!
The next two days should hopefully see the primary mirror opened up to its final configuration, followed by unlocking and orienting each of the 18 individual mirrors to their operational positions.
So close!

I still remember when the first Hubble deep field images first came out and blew everyone away. Images of stellar nurseries are really cool too. I'm excited to see what Webb is going to reveal.

I think that report may have a typo in the distance number. 1 million miles is not 15 million km.

 

[ryanosaur]

L2 is not 15million km, rather 1.5million km. about 1 million miles.

destination that humans will never see it again — 15,00,000 kilometers away from Earth.

clearly they mislplaced the comma.

Or else its the "new" math.

Thanks for the correction.

Better not be. $10B is not pocket change.

Apparently everything is going so smoothly they may have extended the duration of the mission via extremely efficient insertion and orientation. Using minimal burns to get it oriented took less fuel than anticipated and is going to result in extending it's mission window. Pretty cool stuff. There are like 234 different stages to go and lots of room for error still but so far so good.

Jon Michael Godier is a sci fi author and produces a lot of interesting "what if" cosmological videos as well as interesting facts about the universe. He has another channel called "Event Horizon" where he interviews cosmologists and physicists about different topics. He just put this one out a day ago at the time of this post.

The main item to me, is that I really like to know the conditions of the images and especially what type of processing has been applied.

When we get these stunning images, we need to know how the data was processed to get that image.

One of the most common processing techniques is a "color swap" technique. This is where particular EM wavelengths outside of the visible spectrum are "substituted" for wavelengths in the visible spectrum. This then allows us to "see outside of the visible spectrum", so to speak.

These types of images amaze us, and the people uneducated in the field are completely "fooled" by such techniques. I'm not saying that this makes the data bogus, I'm just saying that providing such images and data without providing the conditions and processing will only tell half of the truth.

Yup, most of those cool images actually don't look the way they're depicted because of the color swapping. I imagine there will be a lot of that with JW too since it's an infrared telescope and infrared is invisible to us.

Dr Becky is an astrophysicist with some interesting content and she explains how and why NASA does the color swapping in this video.
