Two new studies have added new evidence to the theory that a major airburst from a meteor or comet occurred over North America, ushering in a 1,400-year cooling period called the Younger Dryas that occurred between the Pleistocene and the Holocene eras. The Younger Dryas saw the extinction of most of the large land mammals across North America, and also the end of the Clovis People, a Paleo-Indian culture. A charred layer of soil, found at roughly 50 Clovis sites across the continent, suggest a massive wildfire that raged continent-wide, possibly caused by such a massive meteor strike.

Former NASA Spacecraft Operator (SCO) Clark C. McClelland has published a revelatory article on his Stargate Chronicles website, regarding a conversation he had with the late lieutenant colonel Ellison Onizuka, Mission Specialist on the Space Shuttle Challenger’s ill-fated STS-51-L mission. The article recounts Onizuka’s recollection of being shown a video of what might have been alien bodies, possibly recovered from a crash site like Roswell.

As researchers learn more and more about the planet Mars, the likelihood of life having developed on the Red Planet increases. Two separate discoveries, one involving the discovery of what may be planet Earth’s oldest fossils, and another that shows that Mars may have had more water on its surface than anticipated, reinforce the idea of life having once thrived on the Martian surface.

An experiment that was conducted aboard — or rather outside of — the International Space Station, proves that biological organisms can survive the harsh environment of space for extended periods of time. The experiment was designed investigate how human expeditions to Mars could one day sustain themselves, and how the biology of extremophiles — organisms that thrive in conditions that would be deadly to other creatures here on Earth — would fare in the harshness of space. The success of the experiment not only provided surprisingly positive results, it also offers new evidence that life on Earth may have originated from elsewhere in the cosmos.
