Chris Lintott on The Galaxy Zooby tvochannel1,968 views
@sbergman27 really good question. Good thing he did compare it to how dark it would get in a room, but even then on what scale did he mean? That much dust from the earth to the center of the galaxy?

What does 10,000 ppm actually mean in a near-perfect vacuum? Is it ppm by volume? Normally, ppm is reported by mass, and that's what I would expect the OSHA limit to be referring to. 3 parts dust mass per 999,997 parts of air mass.

It's nice to see ESA's excellent Herschel Space Observatory in the spotlight. It has fully 17x the light gathering power of the US's best IR space telescope, Spitzer.
