Re: APOD: Tardigrade in Moss (2023 May 21)
Like any alien toward another alien--what is its anatomy? It might be an interesting though horrifying read to learn of all the little things we don't see but eat daily...or how the menu changes from different parts of the world?

Won't say much because I am just amazed and don't understand how one ends up here with the same image lensed 3 times all of which look different to me (JD1, JD2, JD3). ![:) :ssmile:](./images/smilies/smile.gif)

Nice picture! Are camera(s) fixed or adjustable on each solar panel or...? So the Moon's "brightness" is correct because it is a dirt ball compared to Earth's white reflective cloud cover or Orion's white paint?

Re: APOD: Planet Earth at Twilight (2021 Apr 22)
I've heard that Earth is losing O2 in its atmosphere but science does not understand why. All the while CO2 keeps rising. Apparently there is no simple way of stripping O2 from the carbon? If one could do this where would the carbon go--probably grab the O2 right back?

Re: APOD: Arecibo Telescope Collapse (2020 Dec 09)
The collapse was horrifying to watch and hurt because in 1973/74 when the dish was only 10 years old I was a telescope operator there and consider the job one of my most rewarding experiences. I guess the hardest part of getting the job was living in PR, knowing English and basic math, and looking a...

Think of all the exoplanets missed all over our galaxy because their planetary plane is perpendicular (or nearly perpendicular) to Earth.

What a surprise. Let's not talk apparent. Let's pretend we are on a planet in another solar system among these "brightest" stars. Where does the sun fit in?
Any exoplanets? Or are the brightest too bright to "see"?

How does Sol fit into the 25 brightest--I think it is way off the list?
Do any of these brightest have any exoplanets?
Thanks.

It's a beautiful moon. I forget about the reddish (brownish) colorations--is that iron? Still, the Moon looks largely grayish. Why? Mars is redish from so much iron oxidation? Is there any dusty place on Earth where you can take a picture of a footprint that looks grayish like Apollos footprints? Wh...

Is it at all understood why clusters like this form with no rotation in our Milky Way? What did their past and future look like? Has one found any planets around any of these stars using any means? Can things like clusters and nebulas be at all detected in other galaxies? Perhaps most notably Androm...

Re: APOD: Halloween and the Ghost Head Nebula (2016 Oct 30)
If you don't like math, then I should be the perfect person to explain it to you, because I am math-allergic, too. (And at least I hope that I will be able to explain it to you.) So there are bumps and gravity wells in spacetime, and likely even holes. But that doesn't necessarily mean that spaceti...

I've been viewing a couple Great Courses on the universe that, although both are over 10 years old now, describe a 'spatially flat' universe one minute but acknowledge too that one (Hubble Telescope) can see off in every direction some 13+ billion light years and still find galaxies (~14 billion lig...

I wonder if the sort-of-bluish-looking very center of the 'north' pole of Saturn is a break in the cloud structure one robotic Cassini spacecraft might be able to peer through...or better yet descend through when it de-orbits?

The magnetosphere encompasses a large area around Earth... Where is the ISS orbit relative to it/in it? On the ISS is there human exposure/risk? Is the crew "hiding out" within the densest shielded areas until the storm passed?

Re: APOD: An Extremely Long Filament on the Sun (2015 Feb 10
So isn't this "one of the longest ever recorded" filaments being thrown off--aimed right toward Earth--going to produce any effects here when some remaining "elements" of it arrives? I mean not on the Earth's surface but interaction in our magnetosphere?
