In this report from the front lines of astronomical research and theory, Bruce Dorminey shows us that:
- Less than 80 years after Edwin Hubble proved that our Milky Way galaxy was not alone, we now know that our galaxy is only one of at least 50 billion -- each of which may contain billions of planets orbiting stars like our Sun.
- So far, extra-solar planets have been detected by indirect means: perturbations in the radio-timing of pulsars, Doppler spectroscopy, and transit photometry. But direct imaging, especially with the advent of space-based telescopes, will play an increasingly important role in the hunt.
- The teams searching the distant skies cooperate with each other -- they share findings and research techniques at frequent meetings -- but they are also locked in an extremely competitive race that has clearly accelerated the pace of development.
- Astronomers continue to debate the frequency of planets and planetary systems around other Sun-like stars, but the number may be much lower than science fiction writers would have us believe.
- The discoveries made by planet hunters have shown that we may need to revise our definitions. Huge gas giants have been detected in orbit around distant stars, but astronomers have not yet decided whether they should be thought of as oversized "Jupiters" or brown dwarfs.
- Within the next generation, we should have the means to detect life on an extra-solar planet light years away simply by analyzing its reflected light -- and we may even be able to select planets that might be good candidates for human colonization.
