    When we moved to Xenfora some of the signature options didn't come over. In the old software signatures were limited by a character limit, on Xenfora there are more options and there is a character number and number of lines limit. I've set maximum number of lines to 4 and unlimited characters.

James Webb Telescope

Looks like when they release an 80s science-fiction show with "new and improved CGI". I actually prefer the Hubble photo as a photo.

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.
 
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".
 
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.
 

This is what the yt tags are for. Put the string after the '=' sign in the youtube URL in yt tags:


[yt]H9hblaObW4E[/yt]

and you get:


Clicking on the link then gives you a preview, in thread, and doesn't launch a new window or app to view the video if you choose to watch it.
 
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:

Dr. Becky talks about JWST's Pillars of Creation


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.
 
But resembling true colour if we were nearby I thought we decided.

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.

The messy death of a multiple star system and the resulting planetary nebula as observed by JWST

Before the dying star shed its layers, the team proposes that it interacted with one or even two smaller companion stars. During this intimate “dance,” the interacting stars may have launched two-sided jets, which appeared later as roughly paired projections that are now observed at the edges of the nebula. “This is much more hypothetical, but if two companions were interacting with the dying star, they would launch toppling jets that could explain these opposing bumps,” De Marco explained. The dusty cloak around the dying star points to these interactions.

Where are those companions now? They are either dim enough to hide, camouflaged by the bright lights of the two central stars, or have merged with the dying star.

The complex shapes of the Southern Ring Nebula are more evidence of additional unseen companions – its ejections are thinner in some areas and thicker in others. A third closely interacting star may have agitated the jets, skewing the evenly balanced ejections like spin art. In addition, a fourth star with a slightly wider orbit might have also “stirred the pot” of ejections, like a spatula running through batter in the same direction each time, generating the enormous set of rings in the outer reaches of the nebula.
 
NASA’s Webb Confirms Its First Exoplanet (NASA)
Researchers confirmed an exoplanet, a planet that orbits another star, using NASA’s James Webb Space Telescope for the first time. Formally classified as LHS 475 b, the planet is almost exactly the same size as our own, clocking in at 99% of Earth’s diameter. The research team is led by Kevin Stevenson and Jacob Lustig-Yaeger, both of the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland.

The team chose to observe this target with Webb after carefully reviewing targets of interest from NASA’s Transiting Exoplanet Survey Satellite (TESS), which hinted at the planet’s existence. Webb’s Near-Infrared Spectrograph (NIRSpec) captured the planet easily and clearly with only two transit observations. “There is no question that the planet is there. Webb’s pristine data validate it,” said Lustig-Yaeger. “The fact that it is also a small, rocky planet is impressive for the observatory,” Stevenson added.
