Rare Molecule Discovery Announced

After 10 months of keeping the secret, US and European scientists let the eagerly awaiting public know that they found a rare molecule on Venus like the one they found on Mars previously. The molecule was identified as a carbon dioxide isotope that has 10 neutrons instead of 8. The presence of this molecule may effect the greenhouse mechanisms on these planets.
