Recent evidence suggests that the Milky Way is a barred galaxy, and does not have a bulge in the classical sense. One estimate for the thickness of the central part of the Galaxy is ca. 16.000 ly. But if I were you, I would not put too much stock in this answer: astronomers are still learning new things about our galaxy every day, and the figure may well double - or halve - come next month.
An intergalatic, cosmological hernia!
Stars, gas, nebulas and black holes.
The ones in the bulge or halo are older star, the ones in the disk are younger.
It's about 2000 light years thick
The Milky Way is about 100,000 light years in diameter and about 1000 light years thick.
It looks more like a gigantic disk, with a bulge in the middle.
A spiral galaxy or barred galaxy, the milky way is one.
The bulge is a tightly packed group of stars within a larger formation. In the case of the Milky Way Galaxy our "bulge" is the galactic centre.
The milky way is shaped like a discwith a bulge in the middle rather like two fried eggs placed back to back.

as big as ian pearls mom! oh snap burn!
First of all it is a spiral shape from the top. If you look at it from the side, you see a straight line with a bulge in the middle. The line is made up of gas, stars, and dust. To the left of the bulge is the sun. To the right of the bulge is a dwarf galaxy that has combined with the milky way. Inside of the bulge is lots of red and orange stars. In the very center is a huge black hole.
