Weird question: What is the maximum distance of a migrated contrail in a sky of very fast windspeeds? Imagine: A contrail which originated, for example, above...

... fast ... If you didn't see this when it first aired, you should find a copy or check for a rebroadcast. Fascinating stuff, and worrisome. Who'd have ...
Thanks Taylor!, and Bob Hall! (that's very interesting online info!!!). Here's a question I often ask myself when there's a typical "cobweb" or "system" of...
... The maximum recorded wind speed of the jet stream is 400 kph, but the average is 55 kph. A study I found on the web showed only 32% of contrails are long...
That's the oddest lunar feature I've ever seen. It looks like a bench of very uniform width that winds right around the side of those hills. I'll be curious as...
Dear Colleagues, The impact of the SMART-1 is due to take on 3 September 2006 at 05:41 UT, according to the best data now available, with an uncertainty of...

Looking at it again its almost like the edge of the lava pushed up against the base of the peaks, like a lava front reached up to that height then retreated as...
I had thought that too but it's not level with the surrounding mare surface. I'm really just guessing though. The geology people will no doubt have better...
Sorry about that Paolo, at the timer I posted the note here the interview was in the main section of the page, but as soon as a new item was uploaded it got...
... It would be great if they also arranged to digitize the over 100,000 Lunokhod images. These missions are so little known that it would be like sending a...
Paolo, I do wonder what the Lunakhod images would look like and why we don't get to see them. Presumably the Russian Space Authorities don't have the resources...
Yup, that would be about it. I've seen a shorter version of the animation before on one of the science channels. It seems to me that the Drake equation needs...

Thanks for the info Bob! (duration of contrails). Perhaps interesting to know: Some of the broad and "old" contrails contain hexagonal ice-crystals, and the...
Thats a great link Paolo, thanks for that. Theres a lot of info and images to look through here, its like a forgotten treasure trove. I don't know what state...
Hello group, The waxing crescent moon has been very low in the evening sky for us northerners the past few months. On Monday evening I imaged Mare Nectaris in...
Tom, for being only 25 degrees above the horizon that's a pretty good image. I always wonder why the ejecta pattern around Madler is so asymmetric - was it...
... The spectral signature of the Madler area: http://tinyurl.com/ljacf seems to suggest a complex history of lava flows. It might be something similar to the...
If the great lunar imagers are on vacation, or don't even bother when the Moon is below 45 degrees above the horizon, I'm afraid you have got to see only...
Paolo, thanks for the pointer to the spectral signature of Madler. It looks like it might have been a low-angle impact from the NW and then had various lava...
I think a digital camera is a great way to start taking astronomical images. I started several summers ago with a 420mm lens - great moon shots, moons of...
Paolo, Here is a photo of the full moon at only 6.5 degrees altitude: http://www.perseus.gr/Astro-Lunar-Scenes-Metamorphosis-20060512.htm ... aside from being...
... Reading the above LPOD page I get the impression that the concentric crater near Mersenius M was already listed in Chuck Wood's 1978 catalog, and that the...
Hello group, Here is another image I got Monday evening; this is of the Alti Scarp: http://home.ptd.net/~tbash/images/AltiScarpJuly31.jpg Enjoy, Tom...
Now I think I have it right. My apologies for the repeat error postings. Doc Wood in his 8/2/2006 LPOD announced a possible new concentric crater near...
