I’ve researched “Midnight Sun” “Summer Solstice” “Arctic Circle” etc (which yielded the very interesting fact that living above the arctic circle means you don’t have to mow your lawn as much and references to a Stephenie Meyer book. Which probably just means that I’m terrible at research.)
I also found a lot of information about the midnight sun itself, as in where and when, but my question is really what happens just before or just after? How do you get from permanent light to permanent dark in practical terms? I understand that the midnight sun isn’t just one day but rather a longer period of time? Is there ever a time when there is an extremely short night? How long would the shortest one last? I can’t imagine how it works. The sun dips behind the horizon and then comes back up soon after. Is it actually dark during that time or more of a twilight? And how far away would the earliest point in time be for a night like that in relation to the solstice?
This is my first time posting here. I hope my post and tagging is okay. I’m sorry if the question isn’t very clear. That's probably the reason why I couldn’t solve it with an internet search. Any help would be appreciated.
ETA: Thank you all so much for your very detailed and helpful, not to mention fast, responses. This was exactly what I was looking for. I can't thank you enough. It is very much appreciated.
Can anyone recommend sites which would show the orbits of all planets for 1420 or thereabouts? (ETA: Comets would be nice, too.)
I've tried Stellarium, Solstation, and Astronomy Workshop. Search terms like “orbits of the planets” “historical planetary orbits” and “planetary orbits fifteenth century” result in the history of the solar system or the history of astronomy - but I just want to know which constellations the planets were in. A specific search using 1420 as a term came up with something way beyond my comprehension.
I've got a fairy slow connection and don't want to shell out for software!
Any help would be greatly appreciated.
ETA 2: it's for a Shakespeare fanfic, so I don't want to make any astrological howlers - but then again, Shakespearean time is kind of fluid, so I've got a wide choice of dates to work with.
Setting: Character gets put into an escape pod and sent somewhere (she doesn't know the location). She lands on a planet where it's frigid and icy and there's sand like a desert everywhere. There's no snow. I suppose there's not enough moisture in the atmosphere to be snow?
Question(s): 1) is it even possible to be below freezing but not even snow?
ETA: Updated with new list, based on comments
I’m currently working on a plot for an Stargate Atlantis fic (set in 2004) and for the plot to work it is important that I know exactly what skills the people that are on the original (season 1) expedition have. I’ve been working on the scientists and other civilians. The expedition consists of 120 people, 40 military and 80 scientists
I’ve been wracking my brain about what kind of skill set would be taken on a scientific mission to an alien city with advanced technique, knowing it will most likely be a one-way trip. They also know they will have to deal with alien cultures. So for I’ve got:
Number of people – specialism (subdived specialisms)
( Cut for lenghtCollapse )
I have 7 people with some kind of technical PhD, knowing enough about alien technology they can contribute to helping out with serious technical issues. I don’t want to make them astrophysicists as well, but have no idea what kind of technical PhD they can be given
I also have 31 open places for scientists. I am sure I am missing certain fields that would be taken on such an expedition, and perhaps there are too few people in the fields already mentioned.
So, the questions are: what kind of field would the 7 ‘unidentified’ technical PhD’s be in (ANSWERED), and what fields am I missing or do I have too few people for?
The point of the whole exercise is to make the expedition as self-sufficient as possible when they are stranded on an uninhabited world, but keeping in mind they were sent to Atlantis as a scientific exploration mission composed of the best and brightest.
Any help would be greatly appreciated, as I have no idea how to even start googling for something like this, since it’s such a surreal situation.
Right now I'm writing about a habitable planet that is about Earth sized, with one main landmass roughly the size of the Eurasian continent and two small chains of islands roughly the size of the Hawaiian Islands, one just off the southern coast and another several miles east and north. There are two main mountain ranges, both on the western side of the continent, though I'm currently planning on the eastern shore have some cool sheer cliffs to build fortresses on. The continent itself runs from the equivalent of the Tropic of Cancer down to just above the equivalent of the Antartic Circle. There is another continent on this planet at the north pole, which is about as habitable as Antartica. There is one moon, about moon sized.
What I want to know is: what's the weather going to be like? I'm assuming that, with all that water, and very little chance that any storm heading in from the east will hit a big mountain range and break up, that coastline is going to be pretty battered, but let's talk about my background in meteorology!

Also, I have no idea whether or not it's even possible, but what would cause a moon to be sideways? By which I mean that, rather than have a sickle-shape, it would be more of a smile-shape? I kind of want to say that polar orbit would do it, but let's talk about my background in astronomy!
