Life On Other Planets

[Dr. Shane]

Or maybe other type of life altogether.

If you can't find what you seek, redefine what you can find to be what you seek.

Scientists call for wider search for alien life

Quote:

A panel of scientists convened by America's leading scientific advisory group says the hunt for extraterrestrial life should be greatly expanded to include what they call "weird life": organisms that lack DNA or other molecules found in life as we know it...

there is good reason to suspect that other kinds of chemistry could support life as well, the authors of the new report argue. Weird life could differ from life as we know it in small or big ways.

For example, while DNA uses phosphorus in its backbone, it might be possible to build a backbone out of arsenic instead. And life might exist in liquids other than water, perhaps ammonia or methane.
