BOULDER, Colorado -- A special study group has advised NASA that Venus is far too hellish of a world for life to exist on or below the planet's surface. Furthermore, while the potential for life in the clouds of Venus can't be ruled out, the expert panel gauged this possibility as extremely low.

The assessment concluded that "no significant risks" exist in contaminating Venus with Earth organisms on any future landers or atmospheric probes, including balloons. Likewise, any surface materials shot back from Venus or whiffs of its atmosphere returned to Earth pose no significant risk to our planet in terms of "back contamination".
