that is an incredible discovery:
Quote:
Scientists have located an ancient solar system, dating back to the dawn of the galaxy, which appears to be a miniature version of the inner planets in our own solar system.
An international research group, including Yale University professors of astronomy Sarbani Basu and Debra Fischer, announced the discovery Jan. 27 in The Astrophysical Journal. The findings are the result of observations made by the NASA Kepler spacecraft over a period of four years.
The old, Sun-like star, named Kepler-444, has five orbiting planets with sizes between those of Mercury and Venus. Kepler-444 formed 11.2 billion years ago, when the universe was less than 20% of its current age.

YaleNews | Astronomers discover a replica solar system
prior to this discovery it was assumed earth-like planets could not form due to the lack of heavy metals in the universe at that time. With this discovery, we know now that there has been even more time for advanced life to evolve far enough along to tame interstellar space travel, so we should have been visited by now
clearly something prevents the development of abundant advanced life that builds interstellar spacecraft.
