Re: APOD: The Crab Nebula from Visible to X-Ray (2024 Jul 23)
https://apod.nasa.gov/apod/image/2407/Crab_MultiChandra_960.jpg I wasn't aware that the disk surrounding the central neutron star was so relatively large. If the entire Crab Nebula is 10 light-years across, then I guess that the swirling disk must be at least 2 light-years in diameter. Halfway to P...

Re: APOD: King of Wings Hoodoo under the Milky Way (2024 Jul 21)
What I love about Milky Way images is how they remind us that we are seeing a galactic arm edge-on, in every way similar to distant edge-on galaxies. Especially in this APOD, I find, maybe because of the straight tapered aspect of the arm extending from the bulgy center. https://asterisk.apod.com/d...

Why do we assume that an alien technological civilization would already have colonized the Milky Way?
One argument against the presence of other technological civilizations in the Milky Way is that if they were here, they would already have colonized the galaxy. I don't find that argument compelling. Consider ourselves! We count as a technological civilization, yet we are so very far from colonizing...

Intruders? They look to me more like two of the "massive blue clusters" ignited by the now long gone intruder that created the Tadpole's tail. I agree that "Intruder 2" looks just like a massive cluster that formed as a consequence of "Intruder 1's" intrusion into the ...

Re: APOD: Meteor Misses Galaxy (2024 Jul 14)
It is also interesting that the lower part of the meteor's trail is yellow-green. In fact, the meteor clearly changes color during its fiery decent through the Earth's atmosphere from red to green. Why is that, Chris? Okay, it has to do with the composition of the meteor again... The most volatile ...

Re: APOD: Meteor Misses Galaxy (2024 Jul 14)
Indeed, the color is due to the composition of the meteor (and of the atmosphere). And if we had a spectroscopic data, we could say a lot about what the meteoroid was made of. But with only three broadband channels (red, green, and blue) we really don't have much information. The colors of the trai...
