Supernova 2010jl is helping unravel the origin of interstellar dust, the sootlike grains that fill the space between stars. New observations published July 9 in Nature show a shell of dust forming around the dying star within weeks of the explosion. The data support the idea that supernovas are the main dust factories in the universe.

The unusually bright supernova, first seen in 2010, is roughly 160 million light-years away in the constellation Leo. Researchers watched the dust form almost in...
