No. It's one of about thirty permit-locked sectors scattered throughout the galaxy, including the more famous ones around the Orion Nebula region and the Cone Nebula, which are reputed to be Thargoid home space. No-one knows how to obtain the Unknown Permit. Maybe we're supposed to ask the Thargoids nicely, instead of just blowing them up...
There's been much specualtion about what FD are hiding or planning for us inside these sectors. But whoever the aliens are that are living inside the Bleia sectors (there are five of them, Bleia1 to Bleia5), they're staying quiet and not leaving the protective bubble that Universal Cartographics has put around their space.
Each of the Bleia sectors is spherical (unlike the normal procedurally-generated sectors, which are cubes), so the Bleia region is a set of five interconected bubbles. I believe that together the five bubbles are larger than the bubble of human-occupied space. You don't have to fly "through" them to get home; simply fly around them. You will likely have to do this manually, however, as the automatic route-plotter isn't very good at navigating around permit-locked space.
TLDR: you can't go there. Not yet, anyway; FD might actually get around to creating the content intended for that space, eventually, at which time the method for obtaining the permit will presumably be made known.
