The answer to the oldest and most often asked question of mankind:

"Are we alone in the universe?"

"The discovery of life on another planet is potentially one of the most important scientific advances of this century, let alone this decade, and it would have enormous philosophical implications."
- National Research Council

Conditions for life on extraterrestrial planets

 

This site is dedicated to the search for a second earth









You'll find here always the latest news what concerns habitable extrasolar planets. Since this is one of the oldest questions of mankind you should bookmark this site and add this site to your favorites.



Carnegie Institution of Science: "There could be one hundred billion Earth-like planets in our galaxy...". and Berkeley says: "Earth-Sized Alien Planets May Be Surprisingly Common" or "25% of Sun-like stars have Earth-like planets.. (and)...there could be even more Earth-size planets"
The more planets there are the greater the odds that life exists somewhere else in the universe.






 

 

 

 

 



 

Planets todays astronomy thinks are worth a second look  - but don't get too excited because none of these pocesses a moon of the size of our moon (to our knowledge today) which is essential for live on a planet:
