Earth's Nearest Neighbor May Harbor More PlanetsNovember 7, 2017 - Scientific American
The nearest alien planet to Earth may not be an only child. Astronomers have spotted a dusty ring around the nearby star Proxima Centauri, hinting at the existence of other planets in addition to the famous Proxima b, a new study reports. "This...
What Will NASA's Biggest-Ever Space Telescope Study First?December 7, 2017 - Scientific American

Ever heard a sci-fi story about the life of a “ planetary defense officer”? Me neither. Buckle up though individuals, due to the fact that this is precisely what a few of the world’ s premiere area companies have in the pipeline.
NASA and the European Space Agency are both wanting to work with full-time planetary security officers. Their function? To avoid the contamination of Earth by alien forces, and to stop Earth from infecting other worlds. Now I understand all your minds are leaping to famous alien killers from Hollywood; Han Solo in Star Wars, and Will Smith in Independence Day — however unlike Will Smith, this officer will be more ecologist than alien-punching badass. Alien contamination is less a matter of world-busting, soul-harvesting and galaxy-conquering, and more about bacteria in a Petri meal. It’ s simple to obtain brought away with creativities of intergalactic massacre, however exactly what ‘ contamination ’ truly implies is contaminating a beautiful alien environment through human existence. A fine example of this is a probe called the Cassini-Hyugens. The Cassini has actually been orbiting Saturn considering that 2004, and just recently entered contact with an undersea ocean on the surface area of among Saturn’ s moons. Enceladus, the oceanic moon, is covered in cryovolcanoes, which are basically water volcanoes that release saltwater from below the moon’ s ice crust into deep space. The Cassini was struck with one such plume of saltwater, and scientists instantly chose that it needs to be ruined, lest it infect the surface area of a watery moon that might include alien life. The planetary defense officer would more than likely be associated with objectives similar to this. Putting down drones unfortunate enough to experience alien water-worlds is simply part of securing deep space, and maintaining its tricks for complete clinical expedition. Still, directing objectives including water volcanoes on ice worlds looks like something much more futuristic than exactly what we’ re all set for in 2017. Any encounter with alien life, nevertheless, would most likely not be humanoid or mindful life. Simply as infections and trees remain in some sense ‘ alive ’, it makes more sense to anticipate biomasses and natural bonds to make up completely brand-new classifications of life. What, really is, life? We might not have the ability to respond to the concern till we come across all its myriad kinds spread out throughout deep space. Author Nnedi Okorafor, whose book Who Fears Death is set to be adjusted into an HBO series, has actually produced natural spacecraft in her fiction. Think of animals like whales swimming through the galaxies — sounds cool? So exactly what does this insane brand-new task pay? Well, NASA are providing to 187,000 each year for the ideal prospects. I expect practically 100 dollars an hour is reasonable spend for the real-life variation of Will Smith … As a race, we continue to amuse labyrinthine, kaleidoscopic visions of a world split in between the dark unknown of area and the appeal of a forever broadening horizon. Increasingly more, the limitations of sci-fi look like a fractured magical dream more than a super-society held together by Elon Musk and NASA. Could this planetary defense officer be the start of a brand-new area age, charted forth by the 1967 Outer Space Treaty, of worldwide cooperation and irreversible peacetime in the stars? Or will it be a historic notch for us to hang the cable televisions of a brand-new future upon, a call-back to an age when human beings looked for escape from an Earth choking in existential doubt, environment insanity, and the sense of private life ending up being redundant versus a continuous stream of frightening info? The story of innovation, whatever it ends up being, is the story of mankind. Now is a crucial minute, then, to think about: exactly what is the objective of area travel? Is it to offer tickets for journeys to Mars? To achieve understanding for its own sake? Or to look for somebody else’ s paradise?
