environment

Ingredients for the formation of rocky planets discovered in the
innermost regions of the proto-planetary discs around three young stars
suggest that the formation of earth-like planets may not be so unsual

OGLE survey and PLANET collaboration
OGLE: 100 millions stars observed
PLANET: 200 resolved microlensing events analysed (last 3 years)
CONCLUSION: <33% of M-dwarfs have Jupiter-mass companions between 1.5 and 4 AU
