“We know that giant planet migration must have taken place in order to explain the current orbital structure of the outer solar system,” said geologist Stephen Mojzsis at the University of Colorado about the “Giant Planet Migration” that could provide scientists with valuable clues around when life might have first emerged on Earth. “But until this study, nobody knew when it happened.”

Today, AFP reported that tardigrades, Earth’s hardiest microscopic, multicellular species, that were stored inside a “Lunar Library” –a nanotechnology device that resembles a DVD and contains a 30-million-page archive of human history viewable under microscopes, as well as human DNA– likely made it out alive following a crash landing on the lunar surface by Israel’s Beresheet probe in April, the US-based organization responsible for their trip said Tuesday.
Curiosity is now halfway through a region scientists call the “clay-bearing unit” on the side of Mount Sharp, inside of Mount Everest-high Gale Crater. Billions of years ago, there were streams and lakes within the crater. Water altered the sediment deposited within the lakes, leaving behind lots of clay minerals in the region. That clay signal was first detected from space by NASA’s Mars Reconnaissance Orbiter (MRO) a few years before Curiosity launched.

Scientists are making predictions about the biological make-up of advanced, complex aliens, offering a degree of insight as to what they might look like. In Ridley Scott’s movie Prometheus stunning opening, the Engineer, the blue muscle-bound alien, mirrors a modern human, standing by the waterfall drinking black goo to break down his genetic structure and spread life on Earth through his DNA. What we see is the beginning is the creation of Earth. The giant ship has landed on early Earth to drop off the Engineer to terraform the planet and make it sustainable for life.
