The search for extra-terrestrial life has been an ongoing preoccupation for Man, yet how detectable is our own presence in the universe?
Many of the visitors to this site have reason to believe that our planet has been visited by extra-terrestrials for decades, if not longer, but how do other life forms become aware of life on Earth?

A side mission undertaken by NASA’s Lunar Crater Observation and Sensing Satellite (LCROSS) looked at Earth from the perspective of an off-earth civilisation, evaluating how they might determine its potential for sentient life forms.

With the help of a tiny fragment of zircon extracted from a remote rock outcrop in Australia, the picture of how our planet became habitable to life about 4.4 billion years ago is coming into sharper focus.

Writing in the journal Nature Geoscience, an international team of researchers led by University of Wisconsin-Madison geoscience Professor John Valley reveals data that confirm the Earth’s crust first formed at least 4.4 billion years ago, just 160 million years after the formation of our solar system. The work shows, Valley says, that the time when our planet was a fiery ball covered in a magma ocean came earlier.

Will WE? – Will human beings, and the earth, survive? Lots of scientists are worried about this and are trying to figure out what to do about it.

A group of nations has come to the conclusion that human activities have already pushed the Earth system beyond three of the planet’s biophysical thresholds, with consequences that are detrimental or even catastrophic for large parts of the world. Scientists have been warning for decades that the explosion of human activity since the industrial revolution is pushing the earth’s resources and natural systems to their limits. The new data confirm that 6 billion people are capable of generating a global geophysical force the equivalent to some of the great forces of nature, just by going about their daily more
