how do sceintist or professor discover other planet than earth?

Just singular? Sceintist or professor? Maybe you meant scientists or professors. Not that the professors are the leading authority on celestial discoveries. They more of just train others to go outside and look straight up in the air. Usually they use a telescope. In some cases, they consult the spheres. In your case, I'm surprised you even know what the word discover means.

There are an estimated dozens of thousands of lifeforms still undiscovered on our planet.\n\nInvention: you came up with something, had an idea and made it work.\n\nDiscovery: you came across something no one else has, officially or unofficially.\n\nThere is speculation from astronomers that there is another system like ours. Opinion: there has to be.

if they are living on a planet like earth, ver close, if they are living on a very different planet, not very close

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.

The laws of probability makes it a yes to your question.  We are not alone.  In fact earth is just a speck in our own galaxy.  Our galaxy is just one of many galaxies.  Yes it would be amazing to find other beings....provided they were friendly...LOL

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

There are many planets discovered (through pictures of many forms). There haven't been any planets discovered with life on them, but there have been many planets discovered.

Ask those living in other planets!

On the other side of Earth

Most modern telescopes come with a guidance computer. You can just enter the name of the body you're looking for and the telescope will adjust accordingly. \n\nIf you don't have one of those, the best thing to do is follow the course of the sun. Planets are on the same plane, so they will more or less follow the same path that the sun does. \n\nExcept Pluto. He's just nuts.

yes it is possible that phillipino can go search for it but I am sure he will never be able to find one cause in our solar system there is no planet like earth. Earth is at perfect position and its perfect for life to grow. And If u want to go out from solar space you will need super and fastest spaceship to go for search.

There are alot of objects that exist beyond Pluto. Yet, at this point none of these is really large enough to be considered a planet. Check the source link for more info.

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

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.

They discover new planets in the universe everyday. But 10th planet in our solar system has been discovered. It has been couple of months, though. You can read more here: http://www.nasa.gov/home/hqnews/2005/jul/HQ_05209_10th_Planet.html

New planet, discovered by the Samuel Oschin Telescope at the Palomar Observatory near San Diego, Calif., on Jan. 8, 2005,  is yet to be formally named.\n\n(This  newly-discovered object is more distant than the mysterious planetoid SEDNA discovered in 2003. Sedna is designated 2003 VB12.)\n\n Is at least as big as Pluto and about three times farther away from the Sun than Pluto. It is very cold and dark.It is currently about 97 times farther from the sun than Earth, or 97 Astronomical Units (AU). For comparison, Pluto is 40 AU from the sun. \n\nThis places the new planet more or less in the Kuiper Belt, a dark realm beyond Neptune where thousands of small icy bodies orbit the sun. The planet appears to be typical of Kuiper Belt objects--only much bigger. Its sheer size in relation to the nine known planets means that it can only be classified as a planet itself

if ur asking if we, as humans, can be sure the no one else exists on the other planets? then no..no one can be so sure, but the facts gathered about the other planets, such as chemicals in the air, etc... can tell something about the planets..
