Life may yet be found on other planets, however, it will be either far more advanced than us or more likely, far less developed. 261 Earth like planets with atmospheres have been discovered in 216 star systems since 1991. ...read more

A better question to ask would be: is there life within our own solar system? The idea that Earth is the only inhabited planet in the entire universe is absurd. The universe is vast and it might as well be infinite thou...read more

Statistically speaking, Earth is but one planet among millions, possibly billions of habitable worlds in this sector of the galaxy. We haven't even begun to explore the cosmos yet, and I think the chances are very good tha...read more

Yes, quite obviously so, except perhaps to the most myopically anthropocentric. Why? Because it would be extremely presumptuous to think that in the entire universe the only planet capable of enabling the development of li...read more

Life on other planets.... Well, calculating a probability is nearly impossible. Not to mention... Defining life. Good luck there. We have no way of defining life, really. Whatever is out there could be nothing lik...read more

There's no argument: there are lakes filled with liquid methane on Saturn's moon Titan. But does that mean there's life in Titan's darkness and cold? Scientists say the lakes seen in Cassini's July 2006 range from...read more

The question brings many turns of existence to the reality and, outcomes. We can not say for sure if there may be movements of other species on different planets of the universe. I will say that we may come upon true c...read more
