Search for Earth 2.0

A new method for analysing chemical composition of stars — their carbon-to-oxygen and magnesium-to-silicon ratios — may help scientists find alien planets. Computational technique developed by Yale University researcher gives a clearer sense of the chemistry of stars, revealing the conditions present when their planets formed.  System creates a new way to assess the habitability and biological evolution possibilities of planets outside our solar system. “This is very useful, easy diagnostic to tell whether that pale blue dot you see is more similar to Venus or the Earth,” said Debra Fischer, Professor of Astronomy.
