There is no inherent property of exoplanets that means they cannot harbor life. Some probably do harbor life. However, most exoplanets orbit too close or too far from their stars, making them too hot or too cold. A few orbit in the "habitable zone," meaning they may support liquid water and thus life, though there are other considerations that could affect the life supporting capabilities of these planets.
Not in the lifetime of anyone alive today. With current technology, any spacecraft we launch would take hundreds of thousands of years to reach the nearest exoplanets, most of which cannot support human life.
The Hubble and Keppler space telescopes are detecting exoplanets
There are no exoplanets in our solar system. By definition, an exoplanet is a planet that is not in our solar system.
Now we know of 861 exoplanets, with several thousand awaiting confirmation
Cant any more
Not that we know of.
exoplanets
"The 3" is just plain wrong; much more than 3 exoplanets have been found so far.
Of the exoplanets found, the vast majority are gaseous bodies.However, that does not mean the majority are. That is just the majority we have found so far.
about 403.
I believe some of them can, but mostly, the exoplanets are discovered and observed with more indirect methods - especially by analyzing the gravitational effects on the star.
darkrai event. you cant anymore without cheat :P sorry!
