LDN 204 —-> LDN 134 | A Pair of Dust Clouds in Space
***
LDN = Lynds Dark Nebula. Lynd was an astronomer who cataloged clouds of dust and gas in space. These dark nebulae are dense enough to block the starlight behind them. But amazingly, these dark clouds are 250 billion times less dense than the air we breathe. Each cubic centimeter might have only 100-1000 atoms of material. Because they can be many light years thick they add up enough to fully block starlight.
