I knew folks who were working on this back when I was an undergrad in the early 90s. A lot of JPL and CalTech folks live here in town and every house was watching as if it was the World Cup.

I have a stupid question maybe - how big are these Lagrange points? Or are several probes we've sent there kind of orbiting around that point? https://en.wikipedia.org/wiki/List_of_objects_at_Lagrange_points#L2

StanM, Sunday, 26 December 2021 12:33 (nine months ago) link

apparently they are 500,000 miles wide

global tetrahedron, Sunday, 26 December 2021 15:22 (nine months ago) link

500,000 James Webb fans can't be... oh never mind

Heatmiserlou (James Redd and the Blecchs), Sunday, 26 December 2021 15:55 (nine months ago) link

The Lagrange points themselves are infinitely small.

The telescope will circle about the L2 point in a halo orbit, which will be inclined with respect to the ecliptic, have a radius of approximately 800,000 km (500,000 mi), and take about half a year to complete.[34]

okay right, that makes more sense

global tetrahedron, Sunday, 26 December 2021 16:01 (nine months ago) link

ohhh, thank you for the explanation Kim.

I only just learned that this telescope is *not* named after everyone’s favorite one term Senator from Virginia who has killed men with his bare hands.

I assumed it was named after America's favorite songwriter, Jimmy Webb.

Long may it live and prosper! Because micro-meteors are a real thing.

first round of photos july 12th. i expect to be astounded. glad we have this good thing to pay attention to instead of everything else. humans can do amazing things

global tetrahedron, Sunday, 3 July 2022 14:25 (two months ago) link

https://www.youtube.com/watch?v=DrBecky is going to update & explain (enthusiastically because that's what she does) - and this reveal is right in the middle of a big astrophysics convention in the UK too apparently, so they'll all be there together when the images are released.

oh FFS - that's a link to Dr. Becky's channel www . youtube . com /c/DrBecky

so sharp! amazing!

My first thought was "they have Pot Noodles in the United States", and then I re-read the headline and thought "what is a pool noodle is it one of those things is that Gary Busey?". According to the internet a pool noodle is a kind of thing that goes in the pool to help people swim. And it's noodle-shaped. But not noodle-coloured. It's pasta-coloured.

Why not pool spaghetti? Because it's hollow, that's why. Unlike noodles, which are... also not hollow.

Does this mean that the United States' Chinese-American population predates its Italian-American population, or is it just one of those things? The James Webb Space Telescope.

all that gravitational lensing is so mind blowing to see

global tetrahedron, Monday, 11 July 2022 23:21 (two months ago) link

so fucking cool

also it seems like everyone i follow on twitter is talking about it which is kinda great

terminators of endearment (VegemiteGrrl), Monday, 11 July 2022 23:24 (two months ago) link

i completely discounted this before but i'm partially hoping the "UAP" shit that kicked off five years ago was prep for the JWST revealing habitable exoplanets/life. the only thread i have to base this on is bill nelson saying 'five years ago this project had budget problems that were resolved by [whomever's] leadership'. that directly coincides with the first of those crazy NYT articles

anyway yes i want to believe blah blah blah. if the universe is teeming i'll feel a little less bad about the collapse of organized human civilization

Amazing. I was even more excited to see how geeked my 10 year-old was about seeing even just that one image.

Does anyone know what the pixels captured by the CCD look like?

APOD yesterday


Stars created these cliffs. Specifically, the destructive winds and energetic light from the stars in the open cluster NGC 3324 eroded away part of a mountain of dark interstellar dust in the northern part of the Carina Nebula. Several of these stars are visible toward the top of this highly detailed image taken recently by the James Webb Space Telescope

Elvis Telecom, Tuesday, 6 September 2022 13:20 (three weeks ago) link

in case anyone is interested: if you look up Carina Nebula, you don't necessarily see where that picture is located. This explains where it is:

Where are the “Cosmic Cliffs”? The Cosmic Cliffs, whose dazzling image was released by the JWST team yesterday, are located in the open star cluster NGC 3324, in the NE corner of the Carina Nebula, ~7,600 light years away.

great photos
wait but how do you have a NE corner of a nebula in space?

haha, they meant top right on the most usual version of the image, indeed

Neptune is dark in the IR - so dark that a long exposure was required - so long that background galaxies are revealed. Neptune is even darker in the IR than its satellite, Triton, which is covered in highly reflective nitrogen snow that reflects 70% of sunlight. Amazing! https://t.co/L7eUD51viR
