Washington: There could be life on at least half-a-dozen other worlds - besides the Earth - and it may take 20 more years to find them, astronomers have announced.
“At least a half-dozen other worlds (besides the Earth) that might have life are in our solar system,” Seth Shostak, senior astronomer with the California-based SETI Institute in the US, was quoted as saying in media reports.
“The chances of finding it, I think, are good and if that happens, it will happen in the next 20 years, depending on the financing,” Shostak added.
He shared his findings at a Congressional science committee here recently.
Currently, scientists are following three paths in their search for alien life in the universe.
Prominent among them has been the search for life on Mars and the Moon.
