From blob-like jellyfish to rock-like lichens, our planet teems with such diversity of life that it is difficult to recognise some organisms as even being alive. That complexity hints at the challenge of searching for life as we don’t know it – the alien biology that might have taken hold on other planets, where conditions could be unlike anything we’ve seen before. ‘The Universe is a really big place. Chances are, if we can imagine it, it’s probably out there on a planet somewhere,’ said Morgan Cable, an astrochemist at the Jet Propulsion Laboratory in Pasadena, California. ‘The question is, will we be able to find it?’Continue reading To find aliens, we must think of life as we don’t know it
To put things into a perspective, here are the moons of our solar system (including our moon) and their sizes compared to Earth.
In September 2017, Elon Musk, the founder and CEO of SpaceX has revealed a new plan to colonize Moon and Mars with giant reusable spaceships. They are ambitiously planning to send the first humans to Mars as early as 2024 to build the foundations for the first Martian city. But is Mars really the best place for humans to settle? Some scientists, like Amanda HendrixNotes 1, the American planetary scientist, thinks it’s not, and we should be looking somewhere else and colonize Titan, Saturn’s largest moon, instead.Continue reading Living on Mars is a terrible idea, scientist says. We should colonize Titan, instead
Launched on October 15, 1997, NASA’s Cassini spacecraft Notes 1 went into orbit around Saturn on July 1, 2004. Since then, it has taken thousands of photos of Saturn, the second-largest planet in the Solar System, its prominent rings, and moons. And on September 15, 2017, Cassini plunged into Saturn’s atmosphere and disintegrated. Here are the 20 most beautiful photos that the spacecraft has sent back to Earth during its 13-year voyage around the gas giant.
Cassini was destroyed by diving into the Saturn’s atmosphere on September 15, 2017. This method of disposal was planned to avoid potential biological contamination of Saturn’s moons, since Titan, Enceladus, and other icy moons of Saturn may harbor oceans and alien life.Continue reading 20 Best Photos of Cassini’s voyage around Saturn
