Starship Asterisk*

Are you suggesting that the Corona might be markedly different in the portions of it that we can't currently study well (that is, those portions that extend in directions other than in the 2-D radial view we usually see during eclipses)? Possibly? :| Did you notice my edit of my post since your rep...

In a two-dimensional image, the corona extends perpendicularly but what of the part that is directed toward or away from us? The actual corona extends in all directions during a “total eclipse” image of the moon. This may entail a SOHO-like orbiter above the sun’s poles following the Cluster missio...

Can ths be done with a coronagraph image over time, so as to highlight changes in direction and latitude of emissions? To some extent, but no ground-based coronagraph can approach the dynamic range accessible during an eclipse. One tricky point is that what we're seeing here is transient. The Sun i...

Consensus is one of the most important parts of science and the scientific method, though. Speculation is for experts. Starting with a conclusion and then cherry picking for evidence that peripherally supports it is not scientific, and is unlikely to lead to accurate understanding. I agree but even...

When he proposes it in a peer reviewed journal and supports it with evidence, it will mean something. (He is a student whose research interests are all centered on speculative stuff without evidenciary support, not necessarily even rising the the level of scientific theory.) Speculation is natural ...

I read a news: Bruno Bento, researcher at the departament of mathematical scienses at the University of Liverpool, England, states that," perhaps, ( in the Universe), there was not even a beginning" Proposes an infinite past and sees the Big Bang as one more event " in a cosmos that ...

Thanks for the suggestion, Chris, I didn't think of that! :D 🐐 That's a lovely goat, by the way. What's her name? She looks very feminine to me! :D 👱🏾‍♀️ Ann Gretel. She'll be kidding in a couple of weeks. Thanks for teaching me a new word, Chris! I only knew one meaning of the word "kidding&q...

Looking back, how would a solar eclipse have appeared millions of years ago? Let’s say during the Eocene . Hard to say but that era had plenty of action here on Earth. Of our extinction events , many had relevance during the epoch . There was a hot time in the old town that night . :roll:

The conjuction tonight with its beautiful crescent led me back to "The Road to the Snow Moon" from last month. I love finding images you forgot you took. :facepalm: FMI. Is there a possibility that Uranus crept into the conjunction image? IMG_6848.JPG That would be an unexpected surprise....

I was listening to Don Lincoln’s video about Einstein and Newton describing the speed of gravity and he was saying how he, “wished he could have witnessed a debate ”. How might they disagree about gravity's velocity? With AI nowadays, it might actually be simulated. A daunting task I’d like to see ...

Thorny indeed!

I don't think the communications loss was related to distance.

Unfortunately, its end was also ground-breaking.

More like rotor breaking!

Or both? The " soil" looks like it may have been recently disturbed.

So, Perseverance was too far away for a direct image but a flight was attempted in which contact was lost and the incident occurred? Does that mean the real cause was a last-ditch effort to get Ingenuity closer? :? It makes me wonder why it so far away that communication was an issue. :| I don't th...

It’s like asking the question, “What came first the chicken or the egg?”

It seems like galaxies may be coops with very old chickens and all their eggs are either fried, hard-boiled, or scrambled.

Somehow the description failed to mention the star-forming nature of these filaments . From the Pleiades to galaxies to our Magellanic Clouds , filaments seem to be quite important. JWST investigation seems to be hot on the trail. " Musca " not decided to go into that. :|

Besides CO₂, O₂ is projected to look for those ETs.

Beings like us need our O₂.

And to a horticultural guy like me, it begs a question I have never ever considered before: Are celestial phenomenon fragrant? :s Well, the seventh planet certainly has a reputation... :P And it's still waiting for that cosmic bidet... I find it illuminating that jets may arise from different astro...

Besides molecular biosignatures , detecting generated light seems an obvious method of finding advanced civilizations. Since we have a giant telescope that detects IR , could it help find heat generation of an alien nature? Probably not campfires of alien neanderthals :no: but ET’s may need to stay ...

Are there any estimates of the mass or average density of the California Nebula, and the average density of its surrounding medium? The mass is probably that of several tens of Suns. The density is that of a very hard vacuum. And no doubt, the density of the surrounding medium is less dense still! ...

If ISS’s solar panels were as close to the sun as it appears, they’d be pumping out some juice. Parker’s don’t need to be that big most of the time.

But the AC would really need to be cranked up.

The moon is so photogenic. I love to image it this time of year as it rises further north. IMG_6614.JPG A friend was out with his new dog Sadie when he noticed last week's Moon-Venus in conjunction with a photobomber. Moon Venus and Byron.jpeg Unfortunately not all images portray the scene realistic...

Last nights Hunter's moon did have a side kick. Though our two side kicks where fast asleep after a day at the lake on a cool October day.
