g Stars - A Florida Institute of Technology professor of physics and space sciences, has received a three-year, $434,000 NASA grant to study the outer heliosphere. The heliosphere is a "bubble" in the interstellar medium filled with magnetized plasma primarily emanating from the Sun. It extends from the Sun's upper atmosphere to well beyond the planets. See article.
g Life - What is fundamentally required for life to evolve? What types of life could there be in the universe? See podcast.
g Message - To contact an alien civilization, humanity might want to consider a Bracewell probe — a hypothetical concept for an autonomous interstellar space probe dispatched for the express purpose of communication with (an) alien civilization(s). It was proposed by Ronald N. Bracewell in a 1960 paper, as an alternative to interstellar radio communication between widely separated civilizations. See article.
g Cosmicus - More than 9,000 pieces of space debris are orbiting the Earth, a hazard that can only be expected to get worse in the next few years. And currently there's no workable and economic way to clean up the mess. See article.
g Imagining - Among the earliest Star Trek alien races that were exact duplicates of homo sapiens were the Beta III humanoids. But the chance of extraterrestrials looking exactly like us is nil. Why? A note here: The Beta III humanoids show up fairly late in Star Trek’s very first season; until that episode, the series was quite conscious of at least making humanoid aliens different in shape and color — or at least producing an excuse, such as the aliens “assumed” human form for some nefarious purpose. With this race, however, exact duplication of Homo sapiens becomes commonplace in the show.
