So as the plasma cooled and the universe became transparent the photos were emitted, essentially simultaneously, in all directions from essentially all points in the universe. The coolness / redshift is not because of the photons all moving away in the sense of motion rather the coolness...

We see objects either because they emit light [particle or energy] toward us or because light bounces off them in our direction. This is true for all energy not just visible spectrum. We see stars because they emit light towards us and nebula because it is, generally, illuminated by some...

Yes you are correct it is directionally dependent and that is what I was hoping to find. With G2 that's what we witnessed a directional change and a corresponding redshift change. I'm sure studies of orbital pairs have been done I just can't find them. I'll keep looking and thanks for the link.

http://www.usno.navy.mil/USNO/astrometry/optical-IR-prod/wds/orb6 So I found a catalog of optical binaries. But I'm still hunting specific documenation regarding observed red shift variation in these [ Or non optical binaries as well ] over time.

I agree that this is interesting. I've been following it as well. Thanks for the links you posted.

Recently we got to watch G2 as its orbit took it around the black hole at the center of the galaxy. This showed a visual change in direction along with a corresponding redshift to blue shift change on a relatively short timeline. It was really a great event. Binary stars exhibit the same...

Thanks. ... it appears per that link that summer 2016 is target for stars in the Hipparcos Catalogue .

Thanks for the links. The existence of significant quantities of sedimentary rock suggests a substantial quantity of liquid on the martian surface at one time. So i wanted to be sure there weren't explinations of sedimentary in the martian context that didn't assume liquids involved in the...

Do we have any indication of when preliminary data from esa gaia will be made public ? It is a few months behind schedule due to minor complications and such. I am particularly interested in seeing its measure of distance to HIP 85605 among others. Thanks.

Have you seen this being discussed as an explanation for the isotope variance of comets vs water on Earth ? If so I would be interested in reading more on this. I suppose if this was the cause, and if we had a reasonable basis for what the original water isotopes were then wouldn't it be...

I ran into a link from a NASA page over to an Astrobiology webzine. In the article it referenced "sedimentary rock" on Mars. I don't really care about all the other claims of this article, some rather fantastic claims frankly. Rather I am interested in the use of the phrase sedimentary...

Thanks for the info. I've been fascinated by the epicycle model, not for its correctness but for its ability to do a reasonable job describing the observations of those days.

Comets have what is called an "induced magnetosphere". Has anyone been able to document polarity in any of the observed comets magnetic fields yet ? If they have I'm curious how it relates to the orbital plane of the comet. I haven't been able to locate that info if it exists so just...

Right. And this in turn, to my way of thinking, then gets into a bit of feedback where the model determines the type of redshift and the amount of certain types of redshift, in varying ways, impacts the cosmological models. Will be fun to watch over the next few decades.

That was my thinking but was looking for someone to tell me I had missed something. Thanks.
