Scientists say they have found the strongest indications yet of the possibility of life in outer space on a planet more than 120 light years away. That's a little over 1,000,000,000,000,000 (a quadrillion) kilometers from Earth. But not too far for the James Webb space telescope, which has detected particular gases on a planet known as K2-18b. On earth, these gases are produced by living organisms such as algae and other microbes. The discovery suggests the planet may be teeming with microbial
