Will humanity ever leave the solar system or we stuck here forever, sending at best probes outside it?

If this is a real picture from 6 billion kilometer from space and the small dot is Earth, then why doesn't it show other planets?

Look again at that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there--on a mote of dust suspended in a sunbeam.

The Earth is a very small stage in a vast cosmic arena. Think of the rivers of blood spilled by all those generals and emperors so that, in glory and triumph, they could become the momentary masters of a fraction of a dot. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner, how frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds.

Our posturings, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves.

>Named EPIC 204278916, the star is estimated to be about the size of our Sun in diameter, but has only half its mass.

>The researchers report that over 78.8 days of observations, EPIC 204278916 displayed irregular dimming of up to 65 percent for around 25 consecutive days.

Maybe we aren't alone as we thought?

Given an initial position and velocity of a small object in proximity to a much larger one (i.e. a satellite and the Earth), and assuming perturbation-free motion under classical gravity, is it possible to express position of the object as a function of time (r(t) and theta(t), with origin at center of the Earth)?

I've worked on this quite a lot, and in the elliptical case (v(0) < sqrt(2mu/r(0)) I wind up with
>r = s - f*cos(a)
>s*a - f*sin(a) = √(eta)*(t-k)
where a arises in an integral substitution. So far I've been unable to render the second expression into the form a=f(t)

The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment the Earth is where we make our stand.

It has been said that astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world.

Terra-forming Engineering in the future I believe will be necessary, even if our planet doesn't get hit by an asteroid (which it probably will) or a Quasar beam or something relating to that matter, all planets die, eventually. In order for our species to continue & prosper we will need to engineer the environment on another planet to be sustainable for human life. Our species is young, bright, & seems to be headed towards prosperous fronts on this matter, what is your take on this /sci/ ?
