“I believe we are going to have strong indications of life beyond Earth in the next decade and definitive evidence in the next 10 to 20 years,” Ellen Stofan, chief scientist for NASA.
“It’s definitely not an if, it’s a when,” said Jeffery Newmark, one of Stofan’s colleagues.
NASA made these bold claims at a press conference earlier this month. Their confidence comes from their growing discoveries or strong indications of water. So far, they believe or have seen that Mercury, Mars, the Moon, Jupiter, Saturn, Uranus, Neptune, Ganymede, Europa, Callisto, Enceladus, and Titan all have water in their interiors or atmospheres. They are especially certain of liquid oceans on Europa and Enceladus, which both have the three components astrobiologists say are necessary for life- water, energy (volcanic activity), and chemicals used in biological processes. Here’s hoping for microbes.
