Powering extraterrestrial rovers remotely and no evidence of dark matter in Milky Way

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Stars - The most accurate study so far of the motions of stars in the Milky Way has found no evidence for dark matter. See article.
g Life - A geological curiosity known as the Great Unconformity may help scientists understand why life on Earth went through a dramatic period of diversification some 600 million years ago. See article.
g Cosmicus - Future extraterrestrial rovers may be powered remotely by high-energy laser beams shot through miles of thin fiber-optic cables. This new technology could allow robotic probes to penetrate thick layers of ice to explore Antarctic lakes or the subterranean oceans on icy moons like Europa or Enceladus, and even power a new kind of rocket into space.
