g Abodes - A planet-like object has been found to be orbiting a cold, miniature star called a brown dwarf, calling into question just what it means to be a planet.
See article.
g Message - Fifty years ago today, Frank Drake, then a 29-year-old researcher at the National Radio Astronomy Observatory, pointed an 85-foot (26-m) dish at Tau Ceti, a Sun-like star just 12 light-years distant. He'd tuned the receiver to the 21-cm (1420-MHz) — a ubiquitous emission from hydrogen gas that, he reasoned, would be a logical "hailing frequency" for interstellar communication. Drake switched on the dish's amplifier and watched a chart recorder for the tell-tale squiggles that would signal a radio transmission. The modern search for extraterrestrial intelligence, or SETI, had begun. See article.
g Cosmicus - President Obama will seek to promote his vision for the nation’s human space flight program on Thursday, just two days after three storied Apollo astronauts — including Neil Armstrong, the first human to walk on the Moon — called the new plans “devastating.” See article.
g Learning - Here’s a cool set of classroom lessons courtesy of NASA: Astroventure, in which students search for and design a habitable planet. See article.
g Aftermath - How will our views about ourselves affect our views about ETI? See article. Note: This article is from 2002.
