We report the results of the first deep , wide-field , near-infrared methane imaging survey of the \rho Ophiuchi cloud core to search for T dwarfs .
Among the 6587 objects detected , 22 were identified as T dwarf candidates .
Brown dwarf models indicate that at the age and distance of the \rho Ophiuchi cloud , these T dwarf candidates have masses between 1 and 2 Jupiter masses .
If confirmed as genuine T dwarfs , these objects would be the youngest , lowest mass , and lowest gravity free-floating objects ever directly observed .
The existence of these candidates suggests that the initial mass function of the \rho Ophiuchi cloud extends well into the regime of planetary mass objects .
A large fraction ( 59 % \pm 16 % ) of our T dwarf candidates appear to be surrounded by circumstellar disks , and thus represent the lowest mass objects yet found to harbor circumstellar disks .
