The first image from NASA's new space telescope has been revealed, showing the deepest and sharpest image of the distant universe to date. The first image from the $US10 billion ($A15 billion) James Webb Space Telescope is the furthest humanity has ever seen in time and distance, closer to the dawn of time and the edge of the universe. The 'deep field' image released at a White House event is filled with lots of stars, with massive galaxies in the foreground and faint and extremely distant galaxies peeking through. Part of the image is light from not too long after the Big Bang, which was 13.8 billion years ago. "We're going to give humanity a new view of the cosmos," NASA Administrator Bill Nelson told reporters last month in a briefing. "And it's a view that we've never seen before." More images will be released later on Tuesday, including a view of a giant gaseous planet outside our solar system, two images of a nebula where stars are born and die in spectacular beauty and an update of a classic image of five tightly clustered galaxies that dance around each other. The world's biggest and most powerful space telescope rocketed away last December from French Guiana in South America. It reached its lookout point 1.6 million km from earth in January. Then the lengthy process began to align the mirrors, get the infrared detectors cold enough to operate and calibrate the science instruments, all protected by a sunshade the size of a tennis court that keeps the telescope cool. The plan is to use the telescope to peer back so far that scientists will get a glimpse of the early days of the universe about 13.7 billion years ago and zoom in on closer cosmic objects, even our own solar system, with sharper focus. Webb is considered the successor to the highly successful, but ageing Hubble Space Telescope. Hubble has stared as far back as 13.4 billion years. It found the light wave signature of an extremely bright galaxy in 2016. Astronomers measure how far back they look in light-years with one light-year being 9.3 trillion kilometres. "Webb can see backwards in time to just after the Big Bang by looking for galaxies that are so far away that the light has taken many billions of years to get from those galaxies to our telescopes," Jonathan Gardner, Webb's deputy project scientist said during the media briefing, said. How far back did that first image look? Over the next few days, astronomers will do intricate calculations to figure out just how old those galaxies are, project scientist Klaus Pontoppidan said last month. The deepest view of the cosmos "is not a record that will stand for very long", Pontoppidan said, since scientists are expected to use the telescope to go even deeper. Thomas Zurbuchen, NASA's science mission chief said when he saw the images he got emotional and so did his colleagues. "It's really hard to not look at the universe in new light and not just have a moment that is deeply personal," he said. At 6.4m, Webb's gold-plated, flower-shaped mirror is the biggest and most sensitive ever sent into space. IN OTHER NEWS: It is comprised of 18 segments, one of which was smacked by a bigger than anticipated micrometeoroid in May. Four previous micrometeoroid strikes to the mirror were smaller. Despite the impacts, the telescope has continued to exceed mission requirements, with barely any data loss, according to NASA. NASA is collaborating on Webb with the European and Canadian space agencies. "I'm now really excited as this dramatic progress augurs well for reaching the ultimate prize for many astronomers like myself: pinpointing 'Cosmic Dawn' - the moment when the universe was first bathed in starlight," Richard Ellis, professor of astrophysics at University College London, said. "Hubble took my favourite astronomical image of all time: the Hubble Ultra Deep Field," says Elisabete da Cunha at UWA and ASTRO 3D in Perth. "It was taken by pointing Hubble to a dark patch of sky) and just collecting photons for about 10 days. That tiny dark patch of sky reveals over ten thousand distant galaxies. This completely revolutionised our view of the Universe: there are many more galaxies than we imagined. "We will be able to observe even more distant galaxies than with the Hubble - in fact, we expect to observe the very first galaxies that lit up the Universe." Kathryn Grasha from ANU and ASTRO 3D said Webb would allow a view of the "birth of stars within the hearts of the densest, dust-enshrouded cores of molecular clouds". "The 'unknown unknowns' are the most exciting prospect for the next decade. And the breathtaking views of the Universe are guaranteed to ignite the excitement and imagination of the public and inspire the next generation of astronomers," she says. Melbourne's Karl Glazebrook, from Swinburne University and ASTRO 3D said Webb's primary mission was to witness the birth of the first stars and galaxies in the early Universe, "The first billion years of cosmic history has barely been explored. We don't know when or how the first stars formed. This is a complex question as stars produce heavy elements when they die," he said. "All current star formation we can observe, such as in the Milky Way, is from enriched interstellar gas. We haven't yet seen how stars form in pristine gas, which is without any heavy elements - as such a state hasn't existed for more than 13 billion years." Benjamin Pope from the University of Queensland says Hubble was used to find brown dwarfs - halfway between suns and planets but with Webb they could look for much smaller planets to help us understand how Earth and the Solar System formed. While Christophe Pinte, Monash University, Melbourne, would like to see baby planets being born and find out if they are born hot or cold. "I'm interested in stars born in pairs, that have influence over each other for life, a bit like married couples," says Orsola De Marco from Macquarie University. "They create stunning planetary nebulae. One NASA's first photos will be of nebula NGC3132." James Miller-James at Curtin University/ICRAR in Perth said "we're hoping to use the Webb to find out how feeding black holes launch powerful beams of outflowing matter and energy known as jets. Jets from the most massive black holes can affect the evolution of entire galaxies". "As a teenager, I was awed by Hubble's powerful images of the cosmos," he says. "The day I received the first Hubble data for one of my own science programs was extremely exciting. I hope that the Webb will similarly inspire the next generation of scientists in Australia and around the world." - with Australian Associated Press
