The planet in question — HD 189733b — is too hot for the molecules to signal life, but the discovery offers hope for understanding future discoveries of Earth-like worlds, says NewScientistSpace. Researchers from Caltech and University College London used the Hubble Space Telescope to peer at the planet and examined spectral signature of starlight filtered by the planet's atmosphere, to identify different chemicals.

Chief scientist for the Air Force, Mark Lewis in an interview with the Star-Telegram, talks about the USAF's latest development direction. The air force seeks hypersonic missile and bombers for the purposes of reconnaissance and attack. In response to Chinese and Russian anti-satellite developments, the air force plans to develop weapons capable of sustained travel at Mach 6 to allow them to deploy against and take out anti-satellite launch sites before the enemy can fire their missiles. Furthermore, should the US spy satellite network be brought down, the Mach 6 recon flight systems would be capable of filling in. The article also details several programs, both past and present, within the Air Force. Air Force officials hope to deploy a new interim bomber by 2018, followed by a more advanced, and possibly unmanned, bomber in 2035.
