What's more elastic, dirt or water?
Thinking about the effects the earthquake in South America had on earth parameters, I pondered the theorized impact of the asteroid that hit what is now the Gulf of Mexico region, with it's most visible proof theorized being the extinction of the dinosaurs, and the worldwide layer of (forgot the min...

Re: APOD: It s Raining on Titan (2011 Apr 01)
Whoa big fella!.. I agree with the other comment. Lightning in a nitrogen rich atmosphere with a methane river? Uhhh...nitromethane...the fuel that's burned in top fuel dragsters, and give it a spark with a bolt of lightning? Sounds like the ultimate combustion chamber to me. Always wondered if scie...

Re: The Known Universe (2010 Jan 20)
Ok, don't laugh at this but...during the first lunar landing in 1969, the networks had continuous coverage, but would run info segments when trip events were slow. I remember clearly watching a 'short' run by CBS, humorously similar. This pictured in animation format, a zoomout from the earth very s...

1490 manuscript
Were the optics that good in 1490 that Pluto was observed and cataloged?

Re: San Sebastian Moon Halo (2008 December 7)
Well, as old country wisdom goes, my dad always told me a halo around the moon meant rain, and if you count the stars you can see within the halo, that's how many days of rain you will get. Over the years, I've learned that the halo does mean rain, but the star count within it as a predictor ranks r...

Helix Nebula (APOD 04 Sep 2008)
Since this photo of the Helix Nebula is understood to be representative of what will become of our sun, perhaps the main function of life is to develop not only a homogenous society, but to discover how to get the heck out of here and go somewhere else before the inevitable happens.

Plotting backwards (APOD 31 Jul 2008)
If enough galaxy measurements have been taken over the years to assume which direction the majority of galaxies are going, is it possible to plot backwards and see at what point in the universe, according to the theory at least, where all movement outward began? Is it known where our own Milky Way i...

Thanks Orin
Yes, that is the idea, removing the Milky Way stars, and I agree with Animation that example is zoomed in too much. Would seem in this day of data processing, it would not be hard to ID and blank out our galaxy's stars, backfilling the space with something other than a black dot, to get a good idea ...

Removing the Milky Way
Has anybody gone to the trouble of redoing this pic and others like it such as the Hubble Deep Field, and removing all the Milky Way stars so that you could get a view representative of being outside of this galaxy and looking out?
