Sewer gas?

There does seem to be something interestingly unique about spirals.

When considering the vast amount of information we have at our fingertips, we should all follow the Ten Commandments.

Lest we spiral down the rabbit hole.

Ok, can anyone explain to me why exactly it is that Helene is so "appropriate named"? I get from the links that it's something to do with John Herschel suggesting that the moons of Saturn be associated with mythical brothers and sisters of Cronus/Cronos/Kronos/Saturn; Trojan satellites an...

Last night I tried to photograph the aurora with my DSLR with little success. My wife took these with her IPhone. image_123650291 (1)a.JPG image_123650291 (2)a.JPG image_123650291a.JPG With my eye it was not very apparent but her cell phone captured quite a different scene. :? Is aurora photography ...

Simulating a camera’s eye view seems the best we can do.
But imagine what would happen to the camera.

Disorientating to both.

Often, in astronomy, high hopes are immediately doused with buckets of water.

But we can keep our fingers crossed for solid evidence.

I went to a concert in Portland a couple of months ago. Walking from the parking space I walked past a large tree and noticed this plaque in front of it: PXL_20240211_205553559 (1).jpg The city has grown all around the tree; it's flourished and become quite large. Which is pretty neat...nice work, ...

Let's say a black hole is a four-dimensional object.

What about its jet?

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...
