Re: APOD: Shadows of Mountain and Moon (2024 Jan 22)
But, speaking of question marks, the ultimate answer to Life, the Universe and Everything is, as many of us know, 42. Now we just have to figure out what the question is. https://www.allformarathon.com/wp-content/uploads/2021/09/42.jpg The number 42 is, in The Hitchhiker's Guide to the Galaxy by Do...

Re: APOD: The Same Color Illusion (2023 Dec 18)
We're delving into philosophy here, but if two things measured by certain data are identical, what difference does the context make, other than to affect perception (aka, the effect of the whole on human senses)? You're saying that the context is also part of the data? A bullet in a gun is definite...

Re: APOD: The Same Color Illusion (2023 Dec 18)
I make a case that the square values are different because of context. To extract the data out of its context, yes, there is a certain raw value that is identical. But to extract the data and proclaim "puzzle solved" is to abandon the context; in effect, this is abandoning data. Basically...

I'm not sure those lines of galaxies you're positing in this APOD of the Perseus cluster aren't just created by your brain finding meaning in random points. Also, I thought the real "galaxy filaments" were on the order of the size of entire clusters and superclusters, and wouldn't control...

Another anthropomorphic possibility:
In other news today, NGC 3808A Corp. continued its hostile takeover bid of NGC 3808B, Inc., which sought an antitrust injunction to block the merger. The two are expected to battle it out in InterGalactic Court over the next 10K millenia.

So the two bright blue stars at the top of the pic are obviously stars from our galaxy but the stream of stars behind the right star looks to be an irregular galaxy. Is that correct? How far distant is that from the star in front? Also, is the smudge of stars that deceptively seems to be trailing u...

The wow factor for me is the precision with which OSIRIS-REx is operating, namely tagging an asteroid as opposed to crashing into it (crashing = less precise), then dropping off of payload and redeploying to another asteroid. It would seem space missions have squarely moved from the one-and-done mod...

Seeing the proximity of these (and the third of the Leo Triplet) to each other, I wonder how our own sense of the universe would be different if we had nearby galaxies that would be so visible to the naked eye, and cover so much of the night sky. Would we be a little less self centered? Or would th...

Re: APOD: Antares and Clouds (2012 Apr 17)
Supergiant stars are very tenuous. Planets could be orbiting inside of them. (They are still very dense at their cores, but have huge, tenuous outer layers.) I expect that this would explain the nebula around the star as described by today's image caption: Antares is seen on the left surrounded by ...
