Astronomers have now demonstrated that with the advanced technology available in the next decade we should be able to detect biomarkers like oxygen and methane in the planets that orbit dead stars called "white dwarfs" -- and to find new forms of life on those planets.

Universality of circular polarization in star- and planet-forming regions: Implications for the origin of homochirality of life

A research team in Japan has performed deep imaging linear and circular polarimetry of the 'Cat's Paw Nebula' (NGC 6334) located in the constellation Scorpius, successfully detecting high degrees of circular polarization (CP) of as much as 22% in NGC 6334. The detected CP degree is the highest ever observed.
