Beautiful, and I can't help thinking that a low horizon like that would be superb for a meteor camera. :)

Asteroids, meteors, and meteorites


Supposedly shot a few days ago near Barybino, Moscow oblast.  Little info to be found so far.  An article, mostly nonsense, here.

Suggestions for the Name of the SE Game

8998 Story is likely to be minimal, and the player's ship will not have a pre-defined name. The game will center around the player(s) being explorers who set out to map other star systems and planets and return that knowledge back to Earth. Still, some story would help.  For instance, something des...

Suggestions for the Name of the SE Game

I think the name will be better if the game plot is decided first.  For instance, the name of the game could simply be the name of the spacecraft (if the game revolves around the player's spacecraft), which could be anything.  Or if there is a story behind the gameplay, the name could reflect that s...

Suggestions for the Name of the SE Game

"Uncharted Worlds" sound like a play on "Uncharted Land", or "terra ignota"/"terra incognita" which is a term used for well over 2000 years.  So, to avoid "Uncharted Worlds" one could go closer to the source and name it "Universa Ignota/Incognit...

General global warming / climate chage discussion

8919  If we discover this relationship that works "reasonably well" (passes some confidence threshold in a statistical analysis) then we might begin to think the relationship is physical rather than random or uncorrelated. Yes, but we must not get carried away.  Let's say I want to use sw...

General global warming / climate chage discussion

8891 Oftentimes the justification in science is that "it happens to work" I'm sure that has been said about augury as well.  When "it happens to work", science must require that you have such a large observational basis for that without a single exception so you can generalise b...

General global warming / climate chage discussion

8866 True!  But counter-intuitively, not as big of a problem as you might think. The size of that problem varies.  The basic problem is that you add layers of assumptions.  Without sending probes we determine the masses of distant binary stars, and even figure out what kind of molecules they have i...

General global warming / climate chage discussion

One obvious problem is that the data for the SH is much thinner than for the NH.  What do you think about this commentary ? 8863 Correct, but it is also under-represented due to proxy dropout at the end of this interval. Right, as I mentioned, the proxies don't all cover the entire period.  Probably...

General global warming / climate chage discussion

Well, I looked for what you asked and this was the closest I could find which extended into the instrumental record without splicing instrumental observations and also uses an extensive set of proxies.  I hadn't seen it before, but it seems to have attracted some attention (it turned up frequently i...

General global warming / climate chage discussion

8786 Proxy data extend into the instrumental record, and they show an abrupt transition.  It is not simply an artifact of slapping different kinds of measurements together, nor is it an artifact of calibrating proxies to instrumental temperatures. I searched a bit, and I found one paper by Ljungqvi...

8834 I disagree. Been to Universal a few times and it has always been pretty fun. How many children do you have? EDIT: I checked the ticket prices.  If I want to buy three park tickets at Universal for my family online (2 adults, 3 children), it will cost me $1085.  That's ridiculous.  Then add foo...

Total Solar Eclipse 2017

8803 On an unrelated note I wanted to ask, if you remember, how early before totality did Venus appear (or how long could it still be seen after?) It's hard to say two years after, but I do remember that it was visible a while before the totality, but whether a while is 15 minutes or 30 minutes I c...
