Earlier this month a team of researchers made headlines by not finding any signs of alien life in 100,000 galaxies. Their search was based on the theories put forward by physicist Freeman Dyson in 1960. Freeman Dyson theorized that advanced technological cultures would be limited by an ever growing demand for energy. This is the…
Is there an alien world 700 miles below us, in the ocean under the ocean?
The Mariana Trench is the deepest part of the ocean, it’s about 6.8 miles deep, it’s very cold, completely cut off from sunlight and has a pressure of about 1,000 times that of sea level – but life is abundant there. So far, everyplace we’ve found water, we’ve also found life. But what about the…
Suggested Reading: ‘Chemists show life on Earth was not a fluke’
There are a variety of theories about life ‘out there’. We can set aside the ones that say ‘an all knowing old man who lives in the clouds made everything’ but there are those who believe that life on Earth was a fluke. The thinking goes that it life on our planet required a combination…

How Hairspray May Help Us Find Extraterrestrial Life
In an article in Astrobiology Magazine Charles Q. Choi examines the possibility that artificial chemicals may point the way to life on other planets. At one time we used chlorofluorocarbons (CFCs) in air conditioners and products like hairspray. We stopped using them because they are strong greenhouse gasses and damaging to the Earth’s ozone layer.…

Video: Are Water Bears (Tardigrades) from Outer Space?
In 2011 possible evidence of extra terrestrial life was found on a meteorite. In 2007 it was discovered that the tardigrade ( water bear ) can survive in the vacuum of space. The hardy creatures can also survive brutal extremes of heat, cold and radiation exposure and can go extended periods without food or water.…
