I guess there could be hidden planets. Doesn't make much sense to me. I mean anything in the solar system we would have noticed already. Now if you are talking about outside of the solar system then yeah there could be life. Very slim but possible.

Well, there are tons of galaxy's out the undiscovered, there will be a ton of planets still undiscovered aswell :P

mee too even i have heard those news...but frankly i dont believe in them :P...though they may sound intresting xD

Im sure there are places out there that is lik ours, and within our solar system we might have cause there might be places we still havent looked at and we could have planets almost next to us and we dont even notice

There could possibly be thousands of other planets out there that we do not know about or have explored. I hope that someday we can develop the technology to get to those unknown planets.

Yes I have hear about Kepler or super earth in science class and on the news before so if earth ever gets destroyed we can go their (but the bad thing is its many light years away )

Yeah..pretty sure we would have searched our solar system before moving on to searching other solar systems for the sister planets of Earth. o.o

i think that this would be awesome, it just amazes me how even after this long that we are still discovering new things even with the immence amount of technology we have

there are many hidden to the naked eye ? if that is what you mean.

there are loads of planets in our solar system and more being made through asteriods coliding so they arent exactly hidden but just newly formed and there are billions of stars per galaxy and an infinate number of galaxys so there must be a lot of planets with life

They have found already like dozens of Exo-planets, but that is outside of our Solar System, so if they could find one in our own Milky Way is quite exciting. But in regards to extraterrestrial life on other planets, is in my opinion very possible. But traveling to those planets is for now or maybe even impossible.

In our solar system? No. I dont believe it. Because if there were planets, then we would know about it. The Hubble Space Telescope can see that far away. it should be able to see everything.
