The amount of heat and steam produced by society is very small compared with solar input. The water vapor will condensate out very guqickly ("half-life" much smaller than CO2). There is a local effect (heat island) near largish cities, but most of the planet is not covered by large cities. The CO2, on the other hand, migrates everwhere and traps heat again and again and again.
The plane of the Milky Way and the Celestial Equator do not coincide, so the Milky Way appears to the north and to the south of the Celestial Equator. Thus the Milky Way is visible from the North Pole on a clear night. Perhaps you're confusing it with the Magellanic Clouds.
Although the trend is more subtle than for rain, a population density map shows that there are more people living along the southwest coast than to the east. There were reports of red rain along that coast because that's where the rain fell and that's where there were a lot of people to observe it.
Don't presume to know what I think about carbon abundance in meteorites. The parent to my post suggested iron oxide chondrules. As we all know, chondrules, even if they are in carbonaceous chondrites, are glassy spheres of minerals such as olivine and pyroxene (silicates, although olivine can also contain iron). If these did come from a carbonaceous chondrite they have lost the dark carbon-bearing matrix they were embedded in. Mere mechanical grinding isn't enough to break up spores or pollen, and ethidium bromide is not a good test for RNA, only DNA. We can probably agree the analysis was bungled.
The prevalence of the red rain along the southwest coast of India is explained in the paper as being the trail of a meteor that happened to follow the coast. I explain it with this June- Sept precipitation map, which shows the coast receiving 150 cm of rain while areas immediately to the east get 30 cm. Red rain fell in areas where rain is likely to fall. No need to invoke a meteor for which there is little evidence.
The elemental analyses provided in the paper suggest a composition of of mostly carbohydrate with a smattering of something like a hydrocarbon. My guess is that they're some sort of pollen that had their DNA destroyed by ultraviolet light high in the atmosphere and then absorbed water and swelled. Nothing that couldn't have come from our own planet.

Yes it is normal, it's mostly due to Jupiter, which is big enough to throw the other planets around a little bit. Scientists can "solve" the n-body problem and get fairly accurate orbits going back much further in time than 60,000 years.
The current space weatherwith x-ray data and forecast. I haven't looked at SOHO images yet, so I can't say whether the CME is Earth-directed or not, or even if there is one.
XYY males are typically taller than normal and are more statistically likely to end up in prison. The plot of Alien 3 revolves around a prison colony full of them.
Their website says the acceleration is ~.0005 m/s/s, which is 5/100,000 of a g (not a G), and the 'g' referred to here is not a gram, but the acceleration due to gravity at the Earth's surface, 9.8 m/s/s. That's very impressive, considering that acceleration could continue for as long as the sun keeps shining, which is more than enough time to lift something out of Earth orbit. Assuming the craft doesn't trade any kinetic for gravitational potential energy, it could speed up by 1600 m/s in a year (if I remember the number of seconds/year right- ~pi*10^7 s).

Oh, I don't think the bears and mountain lions will feast on on you while you have a flaming bush over you, though of course your protuding limbs will be flailing around in fire. Gotta take the good with the bad.

Go to your preferences page (this link may or may not work) and turn off ScuttleMonkey. And then stop bitching.

Iron oxide chondrules with carbon as the main ingredient? I don't think so... did you see the elemental analyses?
Sue them

Grasshopper mice are known to howl and hunt for meat. They are the wolves of the mouse world.

Actually, it's an oblate spheroid.
Perhaps they're trying to avoid frying the CCDs. It looks like the brighter stars are suffering from pixel bleed.

CCD bakeout and orbital maneuvers come at most inopportune time. It won't be ready 'til Friday morning.

Somebody's ancestors, anyway.
