Life on another Planet

Life on other planets has always been a questionable topic for several people. Scientist all over the world have been trying to prove this topic. We've found out that some planets can hold life but, we just haven't found a way to actually live on these planets. Mars is a planet we've taken a liking too.

Top NASA scientists say that they were closer than ever to be sure that there is life on other planets.

Former astronaut and NASA Administrator Charles Bolden set an hour long conversation about how NASA planned to look for life on other planets.

"Do we believe there is life beyond Earth?" he asked. "I would venture to say that most of my colleagues here today say it is improbable that in the limitless vastness of the universe we humans stand alone."

He added that while he was in space back in 1990, he did not encounter any aliens, but he did look for them.

Though some NASA scientists are looking for signs of life in our solar system, mostly on Mars. The scientists spoke about looking for signs of life on planets around other stars.

A scientist created a way to be sure that a planet can hold life on it. This creation is called The Drake Equation. This equation was written by Frank Drake; a scientist from Green Bank, West Virginia.

While it's not strictly impossible that life in the universe exists. In fact, we don't really know how to look for it. We do, however, know how to look for the conditions that have given birth to the life forms we know.

This is the Kepler mission: to locate planets enough like Earth to be considered habitable. There are several key factors to this. First, the planets must not be too hot, not too cold, but just right. This refers to the planet's orbit position around its star. The distance where must not be so close that it's too hot for liquid water, but not to far away that it's so cold all water freezes.

Among the recent discovery of eight new Kepler planets. NASA announced this at a meeting of the American Astronomical Society on January 6.

"For our calculations we chose to adopt the broadest possible limits that can plausibly lead to suitable conditions for life," said Guillermo Torres of the Harvard-Smithsonian Center for Astrophysics and lead author of a paper describing the findings.
