  Many extra-solar planets and a few planetary systems have been found
indirectly by small periodic radial velocity variations around old nearby
stars. The orbital characteristics of most of them are different from the
planets in our solar system. Hence, planet formation theories have to be
revised. Therefore, observational constraints regarding young planets would be
very valuable. We have started a ground-based direct imaging search for giant
planets in orbit around young nearby stars. Here, we will motivate the sample
selection and will present our direct imaging observation of the very low-mass
(15 to 40 Jupiter masses) brown dwarf companion TWA-5 B in orbit around the
nearby young star TWA-5 A, recently obtained with the 36-element
curvature-sensing AO instrument Hokupa'a of the University of Hawai'i at the
8.3m Gemini-North telescope on Mauna Kea. We could achieve a FWHM of 64 mas and
25 % Strehl. We find significance evidence for orbital motion of B around A.
