Rotating Question Curious About Astronomy? Ask an Astronomer

Why does Barnard 68 appear dark?

I was surfing and looking up pictures and information on the NASA page and I stumbled upon a picture of the Molecular Cloud Barnard 68. Is that dark molecular cloud they were talking about the same as the dark matter I've been reading about on your website?

No, this has nothing to do with dark matter. The picture of Barnard 68 (a dark molecular cloud) is dark because of dust and gas absorbing light from stars behind the cloud at optical wavelengths.
