Negative Energy Plane

[Hanuman]

What info is there on it?

Manual of the Planes
DMG

Any others?

3rd edition D&D: Manual of the planes and Planar handbook. Also Forgotten realms campaign setting has a scant few sentences of information.
Pathfinder: The Great Beyond—A Guide to the Multiverse (3.5 edition rules), Undead Revisited (Specific info for the Nightshades)
4th Edition D&D: Merged with the Plane of Shadows IIRC, creating the Shadowfell. Ask for that location instead.
Unofficial but good quality (3rd and PF, mostly 3.5): Google Planewalker.

There's a very small amount of info in Libris Mortis as well.

See any problems in creating another negative energy plane, and sticking it literally inside the material plane? I'm thinking like far far outside earth's atmosphere, kind of like a black hole in terms of how it exists in space.

Assuming it is self contained, and non-gravitating, I don't see why not. It won't interact with the bulk of Prime due to its remoteness.

So...a Sphere of Annihilation?

I'm thinking far realms, what horrors could burrow into such a sphere, and what would they do once there.

It'd have an event horizon and it would be breachable from the outside... but you may need to abberate to ride the web. Wink.
