APOD for godfry and Debbie T

The Iris Nebula

Well named, is she not? As soon as I saw it I thought of y'all.

[Dragar]

Absolutely beautiful, to my eyes anyway.

Another one I like (and you may like too) is the Keyhole Nebula within the Milky Way, as taken by the Hubble space telescope.

It's gorgeous. Do you ever wonder what such things would look like to our naked eyes? The Hubble colorists do amazing work extrapolating from the data, but I can't help but wonder if we'd actually see these wonders totally differently if they were before our eyes.

Thank you.

Very nice, but I didn't see any info on where I could obtain rhizomes.

That one looks a little Georgia O'Kieffeish if you know what I mean. Or is it just me?

I went back an looked at it again. No...I don't see the O'Kieffeishness (and I think I know what you mean... )

This time I came up with, "Why do they call it that?"

"Is that blob in the upper left what they are referring to as "keyhole" shaped? The one that looks a little like little fist with the middle digit upright in bold digital communication?"

Otherwise, it looks more "amniotic", rather than yonic, on the larger scale.

That's my favourite part!

Yeah. A lot of the time things would look very different as (and I'm sure you know, but for the benefit of other readers) what we are often looking at is pictures taken using light from an entirely different frequency range, shifted down into colours we can see.

I did a little hunt for some comparison and found a picture of the Egg Nebula, which has an image showing it both in visible light and in (obviously recoloured) the infrared range.

Infrared is a frequency range astronomers love to use, as in that frequency range, light can pass through dusty regions of space without being scattered. That allows us to see places that would normally be obscured from our vision.
