The same bit of space but they are not lined up. The JW one is rotated about 1/6 of a turn anticlockwise and zoomed in a bit.plodder wrote: ↑Tue Jul 12, 2022 8:53 amThe slidey thing here: https://www.theguardian.com/science/202 ... axy-images
It's not lined up right, right? These are two different bits of space?

The HST image itself is a composite from at least two imaging sessions as well - you can tell because there are 8 spikes on the brightest star's image - 4 very clear, and 4 offset by about 20 degrees.jaap wrote: ↑Tue Jul 12, 2022 9:40 amThe same bit of space but they are not lined up.

My avatar was a scientific result that was later found to be 'mistaken' - I rarely claim to be 100% correct
ETA 5/8/20: I've been advised that the result was correct, it was the initial interpretation that needed to be withdrawn
Meta? I'd say so!

Or the goalie holding a tennis ball, if you want a purely sports* analogy.Gfamily wrote: ↑Tue Jul 12, 2022 9:06 amFor an idea of the scale, imagine the photo on your phone's screen.
Now imagine you're a goalkeeper and the other goalkeeper is showing you this image from their goalline (I don't know why they have your phone, but bear with me). That's the area of the image* on the sky.
*Appx 7cm at 100 metres.
Which is really big compared to one bit of what I do, which is more like a tennis ball on the moon. Or 7cm at 380,000,000 meters. This is the size of the ring in the EHT images.
And really small compared to the other bit if what I do, which is like 7cm at 10cm for the field of view (45° on the sky, sine rather than tangent because we're working on a sphere). This is roughly the size of the full map that makes up Gfamily's avatar.
Although the main thing I do has about the same image sizes as JWST.
*A sport with goals 100m apart that uses tennis balls. Or we could go to cricket, I guess.

Someone here has done a nice Webb / Hubble overlay https://twitter.com/luckytran/status/15 ... e2L1NRD_bQ
I’ve decided I should be on the pardon list if that’s still in the works
Re: Astronomy and Space
Anyone got one of these self-assembly brass orreries? They look rather nice, but at 60 cm across I'm not sure where I'd put it.
