Can someone explain to me why there are two gaps in the SDSS galaxies/quasars? I can understand the gap at 18h, caused by the galactic center, but why is there also a gap at 6h?

If I can get this to plot using arcGIS software it wouldn’t be that hard to sit down and put reference and proper distance on the entire universe, what a wonderful creation!
Thanks for eradicating my weekends for the next couple years

“Click to exponentiate” hey? That will just reverse the logarithm process.

I’m glad Epsilon Eridani was marked with both a blue circle AND a small 4-pointed black-outline star.

It’s important to draw attention to the star around which Babylon 5 orbits.

Quiet Desperation, there’s a PostScript version at

Would that work?

Dunno why, but I find it really strange to suddenly appreciate that the edge of the universe is ‘only’ about a million times further from us than the edge of our little galaxy. I know the numbers are totally right and that really is the case, but it just seems to make the rest of the universe seem suddenly smaller in my perception as 10^6 is such a ‘small’ manageable number in astronimical terms! If you’d asked me yesterday, without running the numbers I’d have intuitively reckoned it must be billions and trillions of times further to the edge of the universe than to the edge of our tiny insignificant galaxy. Hmmmmmmmm. Maybe it’s just me…

Is there a way to get a vector version? There’s a color plotter down the hall from me at work that uses a big spool of paper. I could totally plot this in lovely high resolution for my office wall.

Zippy, on August 11, 2003, Venus was on the far side of the Sun and Mars was near opposition, making Mars much closer to Earth than Venus.
