Starship Asterisk*

About two days ago, I actually watched a video that featured this photo.

Here it is.

I thought the same at first. I thought CA meant California.
Per wiki: "Eastern Passage is an unincorporated suburban community in Halifax Regional Municipality Nova Scotia, Canada."

Too bad it's so blurry. I've heard that a clearer pic may be available.

Here's a link to a video about it.

Anything Hubble can do, Webb can do better... Not really. The two instruments have about the same resolution, and are designed for very different things. You're comparing apples and oranges. Doesn't the Webb have significantly better resolution at shorter wavelengths, and lower resolution at longer...

Anything Hubble can do, Webb can do better... If Hubble can tease us with a best-ever IR pic of this nebula, then surely James Webb can follow up shortly with its own best. BTW, Why did it take so many years for Hubble to cough this up? Could it be a race against the Webb? https://apod.nasa.gov/apo...

Did someone photoshop out a couple of UFOs on the left?

Was this a single exposure, or is it a composite? Almost certainly a stack of shorter images. Uncooled cameras cannot take such long exposures without dark current saturating their sensors. That's what I was thinking. Also, it looks like a stacked image, but with some areas taken from a single expo...

The write-up says that this contains data from the JWST. Is that correct, and if so, what did the JWST contribute? Here is the JWST contribution. It appears to have focused on the blue star cluster region near the center which they say is "only" 340 light years across. https://www.nasa.go...

Are those dark rocks the few boulders on the very top?

And does anyone know what the darkish dust is composed of, that is seen over most of Mars? It seems to be fine-grained. I propose that it could be made of dead and/or dried microbes. Most likely not, of course.

Yup that's from the JWST alright. I've noticed you can tell there are 6 star spikes whereas older telescopes like Hubble only show 4 star spikes. The picture is the NGC 7469 galaxy. But I like the Hubble picture of NGC 7469 better. It looks more detailed for a poster. Although the infrared is scien...

Three days ago, someone on reddit downloaded and processed raw JWST data. Here's the photo and the link to reddit:

I believe the random motion between the meteors is minor compared to the collision speed between the Earth and the meteor/comet trail. Thats why they seem to travel across the sky like that. Lens distortion like fisheye also affect the image. Does anyone have a suggestion on software for producing ...

Is this supposed to be an accurate composite?
I don't like to suggest this, but it looks somewhat faked... Look at how the meteors are in-line with each other. That's not how a random distribution would look.

Alright, one thing caught my eye here. Is the particularly well lit ruddy dust patch in the middle of the "Gulf" anything particularly interesting? red dust patch in the middle of the cygnus gulf.JPG HBC 722 !!!!! I remember being obsessed with this back in 2010. You can see a closer view...

Are there globular clusters in inter-galactic space? It seems that they are always near, or in galaxies. Why would that be? How do they form?

Here's my photo of the 'supermoon'. It was actually taken the day before, but it was still a supermoon, right? I think it's cool how the moon makes moonbeams as its light shines through the stratus clouds into the hazy air. Also cool that the thunderstorms rose higher than the foreground clouds, and...

Untitled22.JPG I have circled a galaxy that seems to appear four times, the two with the "R" next to it seem to be mirrored. The squared ones seem to be two of a different galaxy, also mirrored. Can lensed galaxies be mirrored? Why do you think that your 4 circled galaxies are the same on...

The answer is simple, I think. The mirrors focus light into one or more of the collectors, and they are rectangular. Here’s a rectangular pic of one of them… E86C69B2-BFED-42FA-83A9-F0D08ADEDC10.jpeg Rob Why didn't they use a sensor that better matched the actual view, or at least use a bigger one,...

How transparent is the surrounding dust and gas? It looks, at first glance, to be opaque, but I see several galaxies through the nebula.

Nice. What surprised me most is that the James Webb's images from its hexagonal mirrors still produces rectangular images with perfect 90 degree corners. Unlike my binoculars that has round lenses and it produces a round image. The explanation was for the old round camera lenses producing square im...

Yep, that's the one I was referring to above.
The center of the galaxy must have been super bright.

The level of detail in the WEBB images is absolutely stunning. What surprises me is the fact that the strongly redshifted galaxies from the early universe - that are now visible compared to HUBBLE - many of these are already highly structured. https://live.staticflickr.com/65535/52209743777_57abc1a...
