Seti@Home produces 150 signal to inspect.
Finding photosyntheticable planets.
Alpha Centauri measured.
[QUOTE]On Saturday, March 15, astronomers announced that Alpha Centauri A is now calculated to be 1,061,000 miles wide (1,708,000 kilometers), or 1.227 times the size of the Sun. The B-star is 748,100 miles across (1,204,000 kilometers), or 0.865 times the Sun's diameter.[/QUOTE

The California researchers plan to head to Puerto Rico this month to use one of the world's most powerful telescopes to more closely investigate the signals that might be from extra terrestrials, a university spokeswoman said. "They are homing in on interesting signals," said Sarah Yang, a spokeswoman at the University of California, Berkeley where the SETI+home research project is based. "They have not said they found anything."

Before the development of photosynthesis and the subsequent rise of oxygen, life on Earth remained single-celled. Oxygen is largely seen as necessary for the development of multi-cellular complex life in other words, higher plants and animals (including humans). The question of complex life on other worlds, therefore, is tied to the possibility of photosynthesis development. But could photosynthesis develop on worlds orbiting stars different from our sun?
