...best hope at finding extraterrestrial life, but Harvard scientists say a new laser-based measuring tool could bring the universe into sharper focus. The astro-comb allows astronomers to discover Earth-size planets, which are most likely to support extraterrestrial life because larger planets tend to be entirely gaseous and inhospitable to organisms like those on Earth. The laser provides a way to measure the near-imperceptible changes in a star’s light that are induced by orbiting planets. Planet gravity minutely affects the color of light emitted by stars they orbit by altering the star?...
...discovery Both stars probably created planets far in the past. Planet formation was thought to occur only when stars are young and enshrouded in dusty and gaseous disks...
...closer to it than Earth is to the sun. That gives the planet a roughly Earthlike year of 260 days and, more important, puts it in what astronomers call the habitable zone, the distance from its sun at which liquid water can exist. The planet is too dense and gaseous to harbor life as we know it, but if it has any moons, they could be warm enough and wet enough to get biology going...
Another answer may be to fix the blood that's on the shelves. Working with dogs, Stamler has shown that the heart-attack rate drops when depleted blood is replenished with liquid NO. Human premature babies born with underdeveloped lungs are already being exposed to gaseous NO to help their tissues get the oxygen they need. For now, the American Red Cross, which oversees the 14 million units of stored blood, is awaiting more studies before changing its processing and storage practices...
Lowell Observatory Astronomer Travis Barman made the discovery by comparing theoretical models that he had developed with previously collected data on HD209458b, a large, gaseous planet located 150 light years away from Earth...
