View Full Version : Discussion: Supernovae Produce Dust More ...

SUMMARY: A new article published in the journal Nature helps settle a long-time mystery about some of the earliest solid particles in the Universe. By measuring supernova remnant Cassiopeia A with the very precise SCUBA telescope, astronomers were able to detect enormous quantities of cosmic dust below -257 degrees celsius. Hot dust had been found in the past, but the colder dust was mostly invisible - until now. It appears that supernovae are extremely efficient at producing the dust that later forms planets, rocks, and people.

One mistake in my writeup, I said it was -257 Kelvin. That's impossible. It's actually -257 Celsius. Sorry. :-)
