Are We Alone?

Life may had existed on Mars because it was a habitable world. In 2004, this discovery was made NASA's Opportunity rover at Eagle Crater that Mars had water. At the Martian surface there was liquid water, and if there was water that means that living organisms like bacteria, may have existed on Mars. Many scientists believe water did existed on the planet because three NASA rovers found rocks with appearance of channels, streams and even oceans spotted by orbiting satellites. A question was brought up to Richard Quinn, a SETI Institute researcher with Ames' Planetary Systems Branch, if Mars was a habitable environment? "Based on what we know about life in extreme environments, interpretations of mission results indicate that we are currently exploring habitable ancient environments on Mars, and I believe that these are solid interpretation...The question is about preservation potential of bio signature rather than intrinsic habitability of the ancient environment." (Quinn, The Daily Galaxy)

Studies shows that extraterrestrial life can come from dying stars. Dying stars can support planets with life. This study comes from a new theory study of earth orbiting white dwarf stars. When a star dies, it puffs off its outer layers, leaving behind a hot core called a white dwarf. A white dwarf air contains water vapor, or even signatures of life, such as oxygen. Abbie Lo...

In July 13, 1860, everyone in the city of Wilmington, Delaware, looked upon the sky and appeared to be a 200 foot long blue flying object about 100 feet in the air above them. A news reporter in the Wilmington Tribune reported that the object "moved in a straight line without any inclination downwards" and gave off "sparkles in the manner of a rocket."

The UFO apparently had an entourage. It was preceded by a pitch-black cloud flying in front. And bringing up the rear, about 100 feet (30 meters) apart, were three "very red and glowing balls." As the object turned toward the southeast over the Delaware River, a fourth red glowing ball appeared. After eight minutes, the mysterious object turned east and disappeared from view, according to "The UFO Book of Lists."
