True. But, we had such threads in past with no apparent need for any cross-reference listings. Yes, there have been multi-apod/single topic before. There are at least three ways to handle them: provide a xref per nereid, combine them all in a single thread as above, or just ignore it and leave it t...

.... (other content skipped) .... New thread: Comet Holmes threads It's a bit of an experiment; after a day or so I'll move it to the Discuss an APOD section. Perhaps I'll make it a sticky, for as long as the linked threads remain popular; perhaps I'll repeat for other, multi-APOD/single topics, in...

From Lance McVay's website http://sacredartichoke.com/coppermine/d ... m=8&pos=14 the photo was added to his collection on October 4, 2007. I don't know if this is when the photo was taken or not. Were there any visible comets in the scope of the picture on this date?

ablebodieman rules violations in Tunguska explosion and Was Tunguska a meteor or a comet?
Those two topics could also be merged with Tunguska event photograph (APOD 14 November)
Could we also merge all of the recent Comet Holmes threads even though they deal with multiple apods.

There is most certainly a largest number. Not in the way you think I mean, however. Just because one *can* count to a number one higher, doesn't mean that anyone has. Somewhere, sometime, someone has published the largest number ever expressed. This is a finite, specific value. Until someone repres...

Infinity means without boundaries. It is said there is no edge of the universe (no boundary). So, by definition, isn't it infinite? To say the set of integers is countably infinite is the same as saying there is no largest integer. You can't count them all because there is always one more to count. ...

No, Smitty. 47 Tuc is the larger one to the left, NGC 362 is the smaller one to the bottom right. They used the description from 2005 June 17; however, the image has a different orientation. They corrected the reference for 47 Tuc, but not NGC 362. See Case's links. I see marek posted the same infor...

Re: Comments and considerations
If you check the apod, the circle of stars is not so circular, and the center isn't so blank. So, if it isn't geometrically perfect, it must be irrelevant. If you had taken a look at the apod that was posted, ( http://apod.nasa.gov/apod/ap060314.html , quite possibly the same picture geckzilla used...

Re: Time
It is an unqualified assumption the universe started from a "Singularity", a singularity is one of the lesser probabilities of how exotic matter behaves. An alternative to the Big Bang is the Big Fizz where the creation of Space/time and Gravity/Mass was not created in one event but over ...

Re: Time
The beginning of the universe is a singularity: a point in space-time at which gravitational forces cause matter to have infinite density and infinitesimal volume, and space and time to become infinitely distorted. If, by a wild stretch of imagination, anything happened 'before' that, there is no w...
