Plants and Water on Other Planets Name: jenny m timis Date: 1993
- 1999 Do you think that there are plants, water,etc. on other
planets? There is certainly water on other planets (Mars for
example), but much more is needed for life. Most planetary
scientists believe that life probably existed on Mars sometime
in the past even if there's none there now, but there's no
scientific evidence for life existing anywhere except on Earth.
That could change soon with the new missions to Mars. A separate
issue is whether or not other solar systems exist, and, if they
do, do they have planets capable of supporting life. Since
there's no scientific evidence one way or the other, this is
largely a matter of personal belief. I like to think there is
life elsewhere. Click here to return to the Astronomy Archives
