Transcript: The direct detection of Earths or even Jupiters is extremely difficult. As seen from afar, a small planet reflects a tiny fraction of the sunlight from the nearby star, and as seen through the Earth’s atmosphere, the light reflected from the planet blurs into the wings of the image of the star. But currently, techniques are being developed using interferometry and adaptive optics that allow images of much greater sharpness to be obtained. This will allow for the first time the direct detection by imaging techniques of Jupiters and even potentially Earth-like planets. With this as a possibility and the use of very large aperture telescopes, enough photons can be gathered from the planet to disperse into a spectrum and look at the atmospheric composition. This prospect is the next stage in the search for life in the universe. Having found that sites for life, planets, are ubiquitous beyond the Earth and the solar system, we now have the possibility of looking at the atmospheric chemistry of extrasolar planets. If we should detect oxygen or ozone in the spectra of these planets it would be good evidence for metabolism at work and good evidence for life.
