DES J0335.6-5403, a celestial object found with the Dark Energy Camera. It is the most likely of the newly discovered candidates to be a galaxy, according to DES scientists. This object sits roughly 100,000 light-years from Earth, and contains very few stars – only about 300 could be detected with DES data. Right: the detectable stars that likely belong to this object, with all other visible matter blacked out. Image: Fermilab/Dark Energy Survey.

Getting Light to Give Up its Secrets

Humans don’t often think about the polarization of light, maybe because our eyes aren’t set up to detect it. But ignoring polarization would be a mistake
