One of the problems with it is that it's overloaded with diffraction spikes. Makes the whole thing seem like a glam shot of a disco. One of the consequences of the extreme sensitivity of the telescope.

Very nice. That full size photo takes a long time to load though.

I've loaded the HST version of that into image editors and rotated it various ways to see what other names it might have had if the accident of orientation had come out differently. It most often looks like a hand to me.

I've always thought it did look more like a hand than anything else, I wonder if there was a bit of... soul searching.. when they originally named it and decided to avoid "the hand of creation".

Webb Offers Never-Before-Seen Details of Early Universe

You can click on the image to see options for larger sizes, although the full-size one is a lot of data. But it's nice to scroll around because it contains lots of galaxies.

That question was clearly answered in the link. Mind you, as a YouTube addict, I am already subscribed to her channel. This channel is a must-watch for anyone who is interested in astronomy. As you did not already know all of this...

I'm against raw url's myself, but "Dr Becky" ought to be enough of an explanation in this thread given how many times she's come up already.

I'm well aware of how the tags work and often use them. It's not a forum rule that they must be used. For this particular video I would actually recommend using the YouTube site to view it because the description has time stamps that allow you to skip to the interesting parts. I usually skip ahead to the news stories myself since I'm not very interested in parts like the ad read. If you just watch it embedded you cannot use these functions.

But at least the [yt] tags let me know Becky's video this time is about the Pillars of Creation, which is more information that you offered in the post I'm complaining about

Come on, is it really too much work to say why you found an item interesting? Your post said simply "Dr. Becky's latest." That's simply lazy! I can't read your mind. With a few additional seconds of thought and a small amount of extra typing, you could have posted:

A few extra keystrokes; a much more informative post.

I never watch YouTube videos directly; I download them to my computer using yt-dlp and watch them using VLC. This lets me bypass the freaking ads and have finer control over the playback.

It would be nice if the forum interface had a button for that, like they do for other tags. To embed a YouTube link in [yt] tags, especially from a mobile phone (I'm not always posting from my computer) is more complicated that using other tags. I don't mind so much when I'm at home using a mouse and keyboard. But I'll try to avoid it in the future.

I see. Well, that's not how I use it or how most people use it. Ads can be skipped and they are how the people who create the content get paid. I've also found YouTube to be a pretty enjoyable experience lately. It has evolved quite a bit from the early days in terms of recommending good content (like Dr. Becky's videos). You curate your own recommendation algorithm with what you choose to watch. I also like to open up the description, and sometimes there are time stamps that allow you to jump to exactly the part of the video that you want to see. Just my 2 cents. I'm sure you have your reasons, but it sounds needlessly complex to me, and you are also depriving yourself of some of the site's features.

It would never cross my mind to use youtube except directly. Smartphones are no good because you are stuck on youtube unless you use premium.
I make the reasonable assumption that a video by Becky with a link posted on this thread is a new item from James Webb.
Thankyou PC for posting exactly what you did.

NASA has released another image of the Pillars of Creation. This one was imaged with MIRI, rather than NIRCam.

Webb Mid-Infrared Instrument Mode Returns to Functionality

The battle station telescope is fully operational again!

The filter wheel that was sticky has been unstuck.

I was curious if the friction sensor was just too cautious, and they would fix it by just cruising through.

It seems the engineering is far more sophisticated, and they can enter that mode from another more safe direction. AFAICT.

If they are very distant, possibly. But that image is from within the milky way. It is nearby.

Very nice. It's labeled a protostar, which Google tells me is "a contracting mass of gas which represents an early stage in the formation of a star, before nucleosynthesis has begun."

I think it depends what is being looked at in any given image, I saw one that was labelled as areas of higher density of dust shown as red and areas of lower density shown as blue. To our naked eye that would probably have just appeared as some slight whitish mist if we could see the dust at all.

I’d be surprised if they weren’t talking about it well before the JWST was launched.
