Somewhere in reading this, I realized it would be really amazing if Celestia included views in non-visible light. (Of course, just having nebulae would be tremendously helpful too.)

A Neptunian orbit-sized parallax baseline would be very helpful in making that 3D dark-matter map that Christopher Jablonski thought of. We could at least find out how much of what we detect is inside our galaxy.

[...] been a lot of exoplanet news lately! Part of that is due to the American Astronomical Society meeting recently — in fact, there was so much I wrote four articles just from that (Part 1,Part 2, and Part 3, [...]

I’m not much for royalty, but the wise king and queen panorama is absolutely stunning.

The Green Apple Cosmos. It certainly looks more of a slice picture of the the Big Bang to me. Beautiful 3D indeed!

Hi Phil, I really liked your wording for describing the growth of galaxies in the BoRG cluster. I will assimilate them for use in my talks. Thanks for your great blog!

Resolving objects 1/3 LY apart at a distance of 3 million LY is impressive in itself!

@dscohl

The blue cluster in M31 is very compact, fitting within 1/3 of a light-year. The two main peaks of the old red stars in the background nucleus are only 5 ly apart. The angular scale of the image is only 3 arcseconds across, so this a very extreme “zoom” into the center of M31.

Are you kidding me? We have dark matter maps??

Can they detect distance as well as direction? Perhaps with parallax? What would a 3D dark matter map look like? Does dark matter tend to clump together? Do I have a lot of questions about dark matter or what?
