One of the most fundamental building blocks in the universe, cosmic dust is a vital ingredient to the growth of a galaxy.

A second image of the same region, taken at substantially longer infrared wavelengths, is dominated by colder gas and cosmic dust.

They found that the mass of lithium, aluminum, copper and lead from spacecraft reentry far exceeded those metals found in natural cosmic dust.

Since cosmic dust is formed from heavy elements like silicon and oxygen, scientists expected the SMC to lack significant amounts of dust.

The data captures radio emission from cosmic dust in these distant galaxies.
