Supercomputer ready to start crunching numbers. The array should be operational in march 2013.
They "add" color, but isn't the color they add representative of how it really looks?
Not sure where to ask this... so, here.
I'm trying to build a world for a scifi (PnP) RPG for our games, my problem is that i want to avoid magic as much as possible. By magic i mean faster than light travel. I don't want to confine the game to our solar system or deal with inconveniently long interstellar travel (decades or centuries of travel, heck even just years of travel is just too much for what i need) either though. Months is fine (and years for unmanned spacecraft).
So, i got this wonderful idea of setting the game to a single solar system with 3 stars, each one having a habitable zone, and thus having multiple habitable (after terraforming) planets, along with moons and asteroids, enough to create pretty damn large empires, to get sort of space opera (or maybe "solar opera"?) feel. Also allows quality, in a real space opera setting planets are merely cities (Planetville) that don't really differ from each other. Want uniqueness.
But for the same reason as i want to avoid FTL: Is this possible? Could a star system have 3 stars, with multiple rocky planets suitable for terraforming, with a few gas giants (with multiple, large moons like Jupiter and Saturn) and asteroids? Can such a system form?
Probabilities be damned, all i need is such system to be theoretically possible.
The system would consist a double star and a companion star (as usual for a trinary). The double stars AB would each have their own planets... but could they ALSO have planets that orbit both?
The companion C would have its own planetary system. And the system shouldn't be too far away to make traveling to it impractical (ie not like Alpha Centauri with Proxima, which orbits Alpha Centauri a quarter lightyear away...).
Could such a system truly work?
EDIT the stars need to be K or G (or F if such wouldn't present problems) class stars all. Or some combination of them. Ms wouldn't have a human habitable zone really, would they?

Planets in Trinary systems have been found.
It really depends on how tight you want to try and pack the system(s). The closer it all is, the higher the tidal forces due to gravity. Theoretically, it is just a matter of finding an equilibrium for the orbits of all the masses inconsideration. Another thought is to scale it down, having Dyson Spheres and habitable stations (like the pics above) in order to create diverse environments within a certain distance of each other, but it sounds like you have a specific direction in mind. Good luck!
http://www.atlasoftheuniverse.com/orbits.html, but it might not be very likely to exist, plus it doesn't show if there are any stable planetary systems possible in such a configuration.
A more likely scenario might be a few Jupiter+ sized planets orbiting a large sun with a relative large habitable zone. With each planet having multiple near earth (variably) sized moons, you could have live originating on a few of the moons. That could possibly create pretty unique life forms.
What would happen if a woman became pregnant and delivered a baby while travelling at the speed of light?
I presume no changes from her perspective right? but from the perspective of those on Earth, how would the gestation period be affected if at all?
aould you please recomend me a +-$100 telescope from amazon?
thanks in advance

That one Saturn photo may be the most beautiful natural shot ever taken, but this has to be second place.

If you think you have the right stuff to help colonize Mars, you'll soon get your chance to prove it.
The Netherlands-based nonprofit Mars One, which hopes to put the first boots on the Red Planet in 2023, released its basic astronaut requirements today (Jan. 8), setting the stage for a televised global selection process that will begin later this year.
Mars One isn't zeroing in on scientists or former fighter pilots; anyone who is at least 18 years old can apply to become a Mars colony pioneer. The most important criteria, officials say, are intelligence, good mental and physical health and dedication to the project, as astronauts will undergo eight years of training before launch.
I can't even wrap my head around this ...

An international team of astronomers, led by academics from the University of Central Lancashire (UCLan), has found the largest known structure in the universe. The large quasar group (LQG) is so large that it would take a vehicle travelling at the speed of light some 4 billion years to cross it.
Sorry, but that's a fake picture. A cool one, though.

"While it is difficult to fathom the scale of this LQG"... difficult, eh? *DIFFICULT?!* IMPOSSIBRU!

THE LARGEST KNOWN VOLCANO IN THE SOLAR SYSTEM
Olympus Mons is a Martian shield volcano of epic proportions that can be seen through telescopes on Earth. It stretches an incredible 25 Km (15.5 miles) above sea level into the thin Martian atmosphere, three times the height of Mt Everest, towering well above the brutal dust storms of the planet.
The volcano is surrounded by 6 km high scarp (perimeter) at its base where ancient lava flows drape over the edges. It spans a ginormous 624 Km (374 miles) in width! To put this into perspective, that is the width of the state of Arizona and wider than the entire chain of Hawaiian islands.
Yet Olympus Mons is not the only large volcano on the planet, it is part of an area of volcanoes known as the Tharsis region. Spanning 4000 km across this region contains 12 large volcanoes all ranging between 10 100 times larger than any volcano found on Planet Earth.
The reason these large volcanoes exist is believed to be due to high volcanic activity. Concentrated stationary regions of rising mantle plumes known as hot spots transfer heat away from the planets interior and deliver lava to the surface. On Earth these hot spots can create chains of volcanic islands due to the movement of the planets tectonic crust. As the plates pass over the hot spot new volcanoes are formed and existing ones become extinct, revealing a distribution of lava over vast areas.
This is what formed the volcanic island chains of Hawaii.
On Mars, this is not the case. It is believed that ancient hot spots rose up from the mantle of the planet, but the crust did not move across them, resulting in a build-up of lava over billions of years forming huge structures.
Surface areas of the western scarp of this volcano have been dated to as little as 2 million years old, which in geological terms can be considered very recent. This suggests that the volcano may still be active, although at a much reduced rate due to the planets cooling interior.
There is much to learn about this intriguing and dynamic planet, we are just beginning.
In the words of the great Carl Sagan, Mars is a world of wonders.

I think with 10x50s, you should be able to make out some definition of craters on the Moon, Jupiter's Gallilean moons (as small points of light) and some definition of Jupiter as a disc. A tripod would probably help to keep your view steady.What kind of views am I going to get with 10x50 binoculars. If my sky map is correct Jupiter is just up and right of the moon tonight it was visible during the day and is still bright now. U.K.er here.

So if someone landed on Mars, how the hell would they get back to earth? Wouldn't it take too much fuel to break orbit?

If you're willing to stay up a bit later, you might be able to make out Saturn's rings (might be a bit of a challenge though ... in binos they'd be quite small). After a quick look, I couldn't find any pictures. The internet is terrible for talking about amateur astronomy and then posting ridiculous HST images alongside it.Cheers. So I'll get decent views of the moon but planets won't be much better? Are there any pictures of what realistic results I might expect to see.
costsoflivingonmars.jpg
does anyone else see a problem with putting costs on these types of monumental leaps in human exploration? I know were a long way off from a society free of currency, poverty and hunger but how will we ever colonize mars when we're limited to being so materialistic in everyday life?
Better yet, hypernova.
