Dec. 2) -- Astronomers have discovered hundreds of Jupiter-like planets in our galaxy. However, a handful of the planets found orbiting distant stars are more Earth-sized. This gives hope to astrobiologists, who think we are more likely to find life on rocky planets with liquid water.
The rocky planets found so far are actually more massive than our own. Dimitar Sasselov, professor of astronomy at Harvard University, coined the term "Super-Earths" to reflect their mass rather than any superior qualities.
But Sasselov says that these planets -- which range from about two to 10 Earth masses -- could be superior to the Earth when it comes to sustaining life.
"Earth is a marginal planet when it comes to conditions we would like to see for complex life to sustain itself," Sasselov notes. "In the family of Earth-like planets, the sweet spot for complex chemistry and biochemistry to emerge and sustain itself lies in planets larger than the Earth."
And Mr Sasselov knows because he visited some of these Super Planets on his last "trip",, conducted a chemical and biochemical tests,, and without a doubt
Earth is marginal. Next thing you know,, he will be applying for a BILLION BILLION dollar grant to take class from Harvard there to taste the sweet spot
Are we having fun yet? Duh!
