The thing that the frigate is going into is believed to be 'The Great Portal', which teleports things (generally massive ships like the frigate) to other Halos. These distances are too far to be teleported to through slipspace, hence the reason for The Great Portal's reason for existance.

if you mean the big structure that the ship is heading towards its sigma 7,if you mean the strange creature at the end no one is sure just yet but its believed it may be a precursor
