Re: APOD: Diamonds in the Sky (2024 Apr 20)

It seems the link that is supposed to direct to yesterday's APOD instead redirects to the APOD for April 18. That's usually remedied by refreshing (reloading) your browser page. Doing that almost always fixes any stale link issues that I sometimes see. Not working. I don't think it's on my end. zxc...

Re: I have a question

Does the nebula from which the sun emerged still exist? Run 3 Even if the nebula has been dispersed, there would still exist highly detectable traces of the emission cloud would there not? No, it no longer exists at all. It's material ended up in the Sun and in the other bodies that make up the Sol...

Re: APOD: Looking Back at an Eclipsed Earth (2024 Mar 24)

Are you sure it isn't the ISS ? The APOD image is from 1999, and the ISS was launched in 1998. So it could have been. Today's APOD, like those on most Sundays, is a repeat, having been used on at least five occasions. It first appeared on 30 Aug 1999, just a few days after the image was snapped, wi...

New APOD is typically released at midnight EST, but today for some reason it has been delayed. Maybe that's why no one has commented yet.

Re: APOD: Martian Moon Eclipses Martian Moon (2024 Feb 26)

The result would be dynamically unstable, and can you imagine the tides? I doubt a 3-body system of Mars, Earth, and the Moon would allow for anything more complex than algae and bacteria to survive. I knew you'd probably say that. 😊 Many planets have more than one moon. Are those systems all ultim...

Ok, but I still find it odd the Rauf would have know - seemingly off hand - about the particular eclipse. But perhaps he also did some sort of search. And I only used Prescott, AZ (where I might want to eventually retire to) because it came to mind. Yes, it wasn't a total eclipse, but my main point...

Yeah, I love the Celestron. But unfortunately due to light pollution, we can't get much of the sky with it. And we have no imaging equipment :?
