A fact from Bok globule appeared on Wikipedia's Main Page in the Did you know? column on 22 January 2005. The text of the entry was as follows: "Did you know

...that a Bok globule is a dark cloud of dense dust and gas, first observed by astronomer Bart Bok in the 1940s, in which star formation is taking place within the H II region?"

Barnard 68 is a Bok Globule

[edit] 3K?

I thought cosmic rays didn't allow clouds to reach 3K. Shouldn't this real ~8K instead?

Magnetic fields can protect objects from cosmic rays allowing some parts of the universe to become heated only by the CMB roughly 3 K. You would expect to find magnetic fields all around a star forming region. Without a citation though, it should be labelled as an estimate and I would just average to 10K.
