I just opened my ceiling light to replace it with another mount. I see a white wire connected to 2 black wires, is that right?
The middle switch controls this ceiling light.

Do you know where the three cables in the open box go to? The answers below make sense for two, but you have three.

@K.A: The third cable almost certainly goes to the next light fixture on the same circuit. See the question I linked above for another very similar example (except with a switched outlet instead of a ceiling light).

The cable with the white wire that's connected to the two black wires is a switch loop:
Normally wires with white insulation are used only for neutrals, but code makes an exception to allow for use of the white wire in a cable used as a switch loop as a hot rather than a neutral.

Should be noted more clearly in your post that a black piece of electrical tape should be wrapped near the end of the white wire in situations like this, so it's easily identified as a live wire.

That is positional coding. It is very important data.
Wire colors in cable are standardized and do not vary. In any cable, if neutral is present, it must be the white. The most likely application for this is in a switch loop. If neutral is not present but an always-hot is, contemporary Code says white must be used for an always-hot. That's to make it easier to identify with a voltage tester. Newer code says white so used, must be marked with tape.
Once you have identified the neutral bundle (all white), a white in a non-neutral bundle is one of these. The fact this is in a lamp makes this most likely a switch loop.
Most likely its partner black is the switched-hot. The lamp will want this switched-hot, and actual neutral.
