The discovery of a star system called GJ 357 was announced today in [a paper]() published by the journal *Astronomy & Astrophysics*. Its star is roughly one-third the size of our Sun and roughly 40 percent cooler, while being 31 light-years away hiding in the Hydra constellation — our cosmic backyard, in the grand scheme of things. ![]() The newly discovered system features three exoplanets, one of which is in the habitable zone, the region where temperatures are warm enough to allow for liquid water and signs of life. The furthest exoplanet in the star's habitable zone, dubbed GJ 357 d, is about 22 percent larger than Earth and "receives about the same amount of stellar energy from its star as Mars does from the Sun," according to [a statement]() by co-author Diana Kossakowski at the Max Planck Institute for Astronomy. https://youtu.be/6bWra2Wvudk ## Just Right The planet is also likely just about the right temperature for life as we know it. "This is exciting, as this is humanity's first nearby super-Earth that could harbor life—uncovered with help from TESS, our small, mighty mission with a huge reach," [said]() Lisa Kaltenegger, astronomer at Cornell and member of NASA's TESS science team. And the likeliness that it could indeed harbor life is surprisingly high, according to the Cornell team. "With a thick atmosphere, the planet GJ 357 d could maintain liquid water on its surface like Earth, and we could pick out signs of life with telescopes that will soon be online," Kaltenegger said. **READ MORE:** [Confirmation of Toasty TESS Planet Leads to Surprising Find of Promising World]() \[NASA\] **More on habitable worlds:** *[Study: Icy Planets Could Be Warm Enough to Harbor Life]()* ## Author I've been at Futurism since 2017, where my role has evolved to encompass design, writing, and increasingly editing. I've always been fascinated by space exploration and advanced transportation, which I've leaned into by interviewing luminaries in those fields while closely following the dimensions of policy and regulation that allow next-generation projects to succeed -- or, sometimes, to fail. I'm also keenly interested in the effects of generative AI on society, policies, and democratic institutions, as well as clean energy, physics and biology, and the vagaries of tech leadership. My work for Futurism has been cited by publications including Ars Technica, Gizmodo, PC Magazine, Jalopnik, Fox News, and the New York Post. I spent my childhood living in locations including Manila, the Philippines, and Geneva, Switzerland, attended McGill University, and now live in Toronto, Canada. Before Futurism I worked at AskMen and a small photography studio. In my free time, I'm an avid gardener, foodie, and craft beer lover, as well as a maker of artisanal hot pepper sauces. I have a magnificent dog named Freida. ### Author social links [Bluesky]()
