![]() Typically, these bursts release a bright flash of radio waves that only lasts for a few milliseconds, and they have no known cause. It’s possible that this group traveled to Siberia and across the Bering Strait, becoming some of the first Americans.Īstronomers have detected a mysterious radio burst in space with a pattern similar to a heartbeat. Now, genetic material from the skull cap has shown it belonged to a female member of Homo sapiens, rather than an archaic human species.įurthermore, the analysis genetically linked the woman to the East Asian ancestry of Native Americans. Primitive aspects of a partial skull and thigh bone, unearthed in 1989 from Red Deer Cave, had caused scientists to question whether the specimens represented a previously unknown group of early humans. Sequencing of ancient DNA has solved the identity of human fossils found decades ago in a cave in China’s Yunnan province. An underwater rover that rolls upside down against the ice’s underside, a steam-powered hopping robot and cell phone-size swimming bots are just some of the prototype ideas.Įxplore our interactive map of planets and moons where scientists want to send robotic missions in the search for life across our solar system.ĭNA analysis of fossils found in Red Deer Cave in China's Yunnan province could shed light on Native American ancestry. Meanwhile, visionary minds at NASA’s Jet Propulsion Laboratory in Pasadena, California, have come up with some concepts for robots that could explore these worlds in ways akin to science fiction. Planning is underway for multiple missions to visit these intriguing destinations over the next decades. Jupiter’s moon Europa and Saturn’s moons Titan and Enceladus may harbor oceans beneath their thick, icy surfaces. Ocean worlds may be the most promising place to look for life beyond Earth – and there are quite a few to choose from in our cosmic backyard. Meanwhile, the dramatic death of a star plays out in the Southern Ring Nebula.Īnd clouds float within the hazy, hot atmosphere of a giant exoplanet more than 1,000 light-years away. Previously invisible areas of star birth glow in Webb’s image of the Carina Nebula, which resembles a Van Gogh painting. Humankind has never seen some of these faint, far-off systems before. The glistening dots in the first image, the deepest infrared image of the distant universe yet, represent thousands of galaxies. The Webb images show how the infrared observatory can peer through space’s dusty environment to uncover unseen aspects of the universe. The image of galaxy cluster SMACS 0723 is "the deepest and sharpest infrared image of the distant universe to date," according to NASA.
