has anyone still discovering what is after the solar system?

i was reading a discover mag..i think it's the june issue this year and the dude said that we are pretty much stagnant on more discovery 'cause we humans just don't have the technology to look farther...our system is at an end of looking..so no one will be looking 'farther' until someone comes up with something more powerful.

Nope, nothing that we have found will be coming very near us on that date.  Just to give an update on the object the Braxton_Paul mentioned, 2004MN4 (now designated 99942 Apophis), has pretty much been put into the clear for the close approach in 2029.  It will come close, but unless something funny happens to the orbit (collision, unexpected outgassing phase etc), it will miss us.\n\nWhat we are trying to get a fix on now is the next close pass by this bad-boy: 2036.  We can't rule out an impact probablitity for that encounter yet.

I don't know about the other 8 planets of our system because no life has been found yet but there are other galaxies and it seems arrogant to believe we are the only ones made with so many possible environments for others.

Ask those living in other planets!

Yeah I think you babble...\n\nThere is no proof that we have been visited, but there are people like Eric Von Daniken who offer proof.\n\nThe most compelling theory is Drake's equation, which shows that given the number of star systems, it is almost beyond comprehension that there isn't intelligent life out there.

talk about pluto. Even though that was a couple of months ago it is still current.

Greetings,\n\nCruithne discovered in 1986.\n\nWe currently have a couple of asteriod size objects oribiting the earth, if that is what you are referring to (Reference the first website listed as sources.)\n\nWe also have any number of Near Earth Objects captured by Earth's gravity, the second link posted.\n\n-matt

if only someone really knew, I think the universe never ends.  I would really hope that we would find new planets outside our own solar system and we would really find other planets like Earth.  I still have time to pay attention and hope they continue to explorer.

You can find the Kuiper Belt beyond Neptune :P\nat a distance of 50 AU from the SUN.

In the first place, we're not entirely sure we've discovered the whole solar system. We just discovered a new planet further out than Pluto. Its name is Sedna, and now we think there may be another planet in our solar system even further out than Sedna. \n     In the second place, it is possible but unlikely that life, intelligent or otherwise, exists on any body in our solar system besides Earth, but scientists think that Europa probably has the greatest chance of supporting life of any body in our solar system besides Earth. That does not mean it is very probably that Europa has life--many scientists think that the probability of that is low. But it is still the most probable.

Yes, other stars with orbiting planets have been discovered. One is Upsilon Andromedae.

Which one? There have been at least 4 but the latest one is still looking for signs of life.  check out http://wwww.nasa.gov

We're still working on trying to find planets, and so far are up to about 100 for sure. Finding moons around those planets is something that's currently beyond us, but it's likely that many of them do have moons. In a galaxcy our size, there could easily be trillions of planets with trillions of moons, but we have no way to know at present.

Of course there is.  You would have to be crazy to think we're the only ones in the universe and the parallel universes, and so on.  They found rust on Mars, which means there was water - therefore leading to the conclusion of life on Mars.  If there was life on Mars, you better believe there's some kind of lifeform billions and trillions of light years away.  No life was discovered yet because we haven't built rockets that are capable of taking us to the destinations of where we haven't discovered yet.

The boundary of the solar system is probably very loose indeed. You could perhaps mean where the Suns gravitational influence is canceled by other stars or where the solar wind no longer reaches. Dust and space is most likely what you'll find. Space is pretty boring, trying to understand it is not :)

Wow, just asked my 10year old same question.  He said it is a planet they have recently discovered about twice the distance of Pluto.

More than a decade after the first planets beyond our solar system were found, astronomers have discovered about 200 of these "extrasolar planets," as they're called. Using a common-sense definition of potentially habitable planets, coupled with extensive computer simulations, scientists have calculated how many potentially habitable planets might be detected around other stars by the SIM PlanetQuest mission. ("SIM" stands for Space Interferometry Mission.) \n\nThe mission, scheduled for a launch in the next decade, will target planets with specific traits in common with Earth: a similar mass and an orbit in the "habitable zone," not too close and not too far from its parent star. With this mass and location, it's believed a planet could have liquid water on its surface and an atmosphere -- conditions considered necessary for life to gain a foothold. \n\nThe science team has shown that, in a survey of the best 120 candidate stars for hosting such planets, SIM PlanetQuest would have the sensitivity to find: \n\n-- Planets smaller than Earth around six stars \n\n-- Planets smaller than twice Earth's mass around 24 stars
