Starship Asterisk*

10 years ago, Sally, when I proposed that Voids were filled with anti-matter, and expanding, I was seen here as a laughingstock .. however .. the idea has now been fairly well confirmed. https://www.universetoday.com/84934/antigravity-could-replace-dark-energy-as-cause-of-universes-expansion/ I've ...

According to my new theory [Mass Vortex Theory], the moon should have a boundary layer similar to the Moho -- between the crust and mantle -- that contains water. So if we were able to drill through about 5 km of basalt in a deep mare region, a lunar colony could have sufficient water for a long tim...

Actually, I quote you in the book (in the body and an endnote). :) Quote in the body: “All that matters is gravitational attraction and the density of orbital material. If the density is high enough … the material will flatten out (just like spinning pizza dough).” — Chris Peterson, Cloudbait Obser...

Even before the formation of pebbles and such, the standard theory of planet formation does not explain sufficiently to me how it is that gravity overcomes the coulomb force between atoms in the protostellar disk of gases to form the minerals and molecules of rocky material. Nor to me either, come ...

Regarding your other point about being featured in a peer reviewed journal. I am aware that this is this a common sentiment. I have to wonder, however, if at least some scientists might be willing to look at a theory that explains... It the theory explains these things, it will most certainly be ac...

Star formation is easy compared to the planet formation problem. The riddle to be solved is how to bridge the gap between pebbles and objects big enough to grow by gravitational attraction. Rocks and boulders will tend to just bounce and shatter off each other when they collide, causing the opposit...

An hypothesis (not a theory) is worth paying attention to and expending time, energy and money on testing, if and only if it is published in a peer reviewed journal. If you're self-publishing you won't be taken seriously. That's life. Rob Rob, You may be interested to know that there are multiple c...

What are the top 2 hallmarks or features of a theory on star-system formation (including planet formation) that would make you feel that the theory is worth attention and testing? I'm really close to finalizing my book that puts forward a new theory of planet and star formation called Mass Vortex Th...

7000 light years is too small a distance for it to be relevant for us observing the evolution of the Veil Nebula, but shouldn't the accelerated expansion of space matter when think about the distance in the past that we are observing? Cosmological expansion isn't uniform. At short distances, gravit...

It's not that we don't care ... it's simply that we don't know precisely when the explosion "actually" happened. Hence, we'll just call the accurately known spacetime interval Δs "the time" : I'd like to test for understanding. I get the space-time interval (from past physics co...

It's not that we don't care ... it's simply that we don't know precisely when the explosion "actually" happened. Hence, we'll just call the accurately known spacetime interval Δs "the time" : In four-dimensional spacetime, the analog to distance is the spacetime interval Δs : ht...

Chris, thanks for the extra info. You provided the colors for the different elements in the plasma and a scale for the image.

It looks like a plasma to me with multi-element ionized gas.

I agree --- Outstanding closeup!
Wow!

Source: https://www.spacetelescope.org/news/heic0817/ Today's APOD is a very interesting portrait of a fascinating active galaxy. It looks different than the most common Hubble pictures of NGC 1275, of which one...

Thank you Ann, Bruce, Neufer, and Chris for all the good discussion and information about lensing, the Hubble constant and dark matter. I know that it takes time, and you may not realize the value of your contributions live on for many people...even after the day of the APOD image.

Sincerely,
Sally

Thanks Ann! Actually that faint looking dot is indeed Mercury. It was at mag. -0.2 back then; I had to shoot it with the intervening clouds and the twilight had already begun. The brighter light above Mercury is the Moon, which was a thin crescent with earthshine. Tunç Tezel http://www.twanight.org...

Great image! It's fun to see the sky between two horizons, the eastern morning one at left and the western evening one at right. Thanks a lot for the annotation! I would never have found Uranus, let alone Neptune, without it. The labeling of Mercury is slightly confusing, though. Immediately to the...

Hope this helps.

Yes, thank you very much!

Please could someone mark the appropriate locations in this APOD image to show the location of:
HDE 227018
Cygnus X-1

I love it!! I like the way the map immediately shows where good night-sky viewing can be had. I like the way that it shows population distribution. I like the way the globe is cut up to avoid some of the usual distortion of a flat map. I like the colors... and the WHOLE THING! Thank you VERY much AP...

This video really is VERY cool. I especially liked the close-up images. The movement of Mercury is so smooth and "pure." We know that the movement of a planet works the way we see it here, but I think this is the first time we've actually seen it (with this kind of video quality). The vide...

Bob,
Thank you for the annotated image. It helped to satisfy my curiosity.

Would someone be willing to label the image?
I'd like to make sure of where each named object is.

Thanks in advance.

The middle-right, white-spot impact appears to show material from the impact spread out thinly like a splatter from the original collision. After contemplating Ceres last year, my guess was that the white stuff is a magnesium-based salt. Then, I read that the mission team was closing in on its concl...
