Kane and Gelino's research suggests that habitable zone around stars might be larger than once thought, and that planets that might be hostile to human life might be the perfect place for extremophiles, like lichens and bacteria, to survive. "Life evolved on Earth at a very early stage in the planet's development, under conditions much harsher than they are today," Kane said.
Kane explained that many life-harboring worlds might not be planets at all, but rather moons of larger, gas-giant planets like Jupiter in our own solar system. "There are lots of giant planets out there, and all of them may have moons, if they are like the giant planets in the solar system," Kane says. "A moon of a planet that is in or spends time in a habitable zone can be habitable itself."
As an example, Kane mentioned Titan, the largest moon of Saturn, which, despite its thick atmosphere, is far too distant from the sun and too cold for life as we know it to exist on its surface. "If you moved Titan closer in to the sun, it would have lots of water vapor and very favorable conditions for life."
While SpaceX works on giant reusable rockets to reach Mars, other companies are working on technologies to keep colonists alive on the red planet. Relativity Space has made the world's largest metal 3D printer, called Stargate, to print rockets, tools, and other useful objects off-Earth.
When humans take the drug MDMA, versions of which are known as molly or ecstasy, they commonly feel very happy, extraverted, and particularly interested in physical touch. A group of scientists recently wondered whether this drug might have a similar effect on other species—specifically, octopuses, which are seemingly as different from humans as an animal can be. The results of their experiment, in which seven octopuses took MDMA, were “unbelievable.”
