Optimal band for extra solar planet detection: sub-millimeter spectral region

摘要

Most of the research on the exo-solar planet detection in the last 20 years concentrated first on the visible and then the IR region. The technology developments there were most pronounced, especially in terms of the telescope fabrication. We propose the sub-millimeter region where the signal to noise ratio is 1000 times more favorable than in the visible. We propose to place the observatory on the far side of Moon, where the stray-light noise from the Earth, near-Earth objects, and the Sun will be avoided.
