Astronomers have captured enough light from two planets far beyond our own solar system to reveal details of their chemical make-up, marking a new phase in the search for extraterrestrial life.

The research builds on earlier work with the Hubble Space Telescope which detected sodium, hydrogen and carbon from starlight passing through the atmosphere of the planet with polycyclic aromatic hydrocarbons and shows that it is possible to measure the chemical make-up of "extrasolar" planets - those outside our solar system - and to hunt for the chemical markers of life in the far-flung reaches of space.
