They are the smallest manifestations of dark nebulae with sizes less than 3 light years across, and are most easily visible when silhouetted in front of emission nebulae or reflection nebulae. Though upper limits are difficult to decide, they generally contain between 0.1 and 2000 solar masses of gas and dust (above this they are simply known as dark nebulae), and form isolated stars, not massive star clusters. Bok Globules typically have temperatures of around 10 Kelvin.

What is a dense pocket of matter that is the beginning of a star?
Stars form in molecular clouds and nebulae, consisting mostly of hydrogen, with some helium and lithium. When enough mass (along with a few other factors) accumulates, such clouds begin to collapse under their own weight, forming dense pockets of dust and gas called Bok Globules. As Bok Globules increase in mass, their cores undergo more and more pressure, and when the cloud reaches hydrostatic equilibrium, a protostar forms at the center.
What is a thick globule?
Thick globules are called bok globules. They are small interstellar clouds of very cold gas and dust that are so thick they are nearly totally opaque to visible light.
What celestial bodies begin with b?
Black Holes. Black dwarfs, Binary stars, Bok globules, Blue stars, Blue-white stars, Barium stars, Beta Cephei variables, Beta Lyrae stars,

What are the two main types of bright nebulae?
emission nebulae and reflection nebulae.
What is a diffuse nebulae?
In astronomy, diffuse nebulae is the general term for illuminated nebulae. The three types of diffuse nebulae are reflection nebulae, emission nebulae and supernova remnants. They are diffuse as opposed to the non-diffuse dark nebulae, i.e. the particles have spread out.
What are examples of nebulae?
Planetary nebulae (the cat's eye nebula) Emission nebulae (the orion nebula) Dark nebulae (the horsehead nebula) Supernova remnant nebulae (the crab)
Do The Beatles bok bok in their songs?
No. The only song with "bok bok" in it was the ending to "Good Morning, Good Morning", in which you hear a sound loop of chickens and a rooster. But, no other songs have that. And, no Beatles actually say "bok bok".

Nebulae - band - was created in 1992.
