NASA’s new flagship astronomical observatory was launched into space from Florida on Sunday on a mission to probe some of the biggest mysteries in astrophysics and cosmology.
“Webb is designed to be able to probe very deeply and with exquisite sensitivity into the universe, so we can find rare things in the early universe,” McEnery said, while Roman offers “the large vision that complements the deep views that Webb provides.”
Roman instead is able to take panoramic views. NASA likens Roman to a camera’s wide-angle lens and Webb to a zoom lens. “One of the most exciting aspects of Roman is its discovery potential. President Donald Trump’s administration tried during both his first and second terms to reduce or eliminate funding for Roman, but Congress preserved it. The telescope will focus on dark matter, dark energy, exoplanets and the physics of distant stars, giving scientists a wider look at how the universe works.
Because of the time it takes light to travel, webb is capable of looking across vast distances and back into deep time,. The launch is scheduled for no earlier than 7:26 a.m. EDT (11:26 GMT) on Sunday, August 30, from Launch Complex 39A, NPR reported. The forecast gives the launch a 50% chance of favorable weather conditions, while a backup launch window on Monday at 7:22 a.m. ET has better conditions, with only a 30% risk of weather interfering.
Using Roman to gauge dark matter’s pull and dark energy’s push across the universe will bring scientists closer than ever before to solving both mysteries, according to NASA. Historically, major astronomical observatories have often made their most important breakthroughs in areas that scientists did not anticipate before launch,” cosmologist Mustapha Ishak of the University of Texas at Dallas, a member of Roman’s scientific collaboration, told Reuters. Roman’s launch comes nine months ahead of schedule, according to NASA. (Except for the headline, this story has not been edited by NDTV staff and is published from a syndicated feed.) Earlier reporting noted: Nancy Grace Roman Space Telescope: What to know about NASA’s new space observatory NASA is preparing to launch the Nancy Grace Roman Space Telescope, a new space observatory that is expected to help scientists study some of the biggest mysteries in the universe.
Webb has provided a new understanding of the early history of the universe, finding among other things that primordial galaxies formed sooner and were bigger than previously known. Earlier reporting noted: SpaceX will launch the Roman Space Telescope on a Falcon Heavy rocket from NASA’s Kennedy Space Center in Florida. Earlier reporting noted: Weather could affect Sunday’s launch.
The Nancy Grace Roman Space Telescope will build on the capabilities of other orbiting observatories such as the James Webb Space Telescope, launched in 2021, and the Hubble Space Telescope, launched in 1990.
The telescope is designed to investigate cosmic enigmas such as dark energy and dark matter, while also testing gravity at vast scales and searching for exoplanets, as planets beyond our solar system are called. There were some weather concerns ahead of the launch but the rocket carried the telescope into space through blue skies and some scattered clouds. Roman will help in the understanding of two mysterious cosmic components – dark energy and dark matter – by creating the most comprehensive 3D map of the universe to date. Its main survey, to take more than a year to complete, will cover more than two billion galaxies. The universe’s contents include ordinary matter – stars, planets, gas, dust and all the familiar stuff on Earth – as well as dark matter and dark energy. Roman also will conduct one of the most comprehensive searches ever for exoplanets. It is expected to discover thousands of new ones and provide the first statistical census of planetary systems similar to our own.
The Nancy Grace Roman Space Telescope, a roughly $4 billion project, was carried aloft from NASA’s Kennedy Space Center aboard a SpaceX Falcon Heavy rocket. Roman will travel through space toward an orbital location called Lagrange Point 2, situated about a million miles (1.6 million km) from Earth. Roman will build on the capabilities of other orbiting observatories such as the James Webb Space Telescope, launched in 2021, and the Hubble Space Telescope, launched in 1990. The Big Bang event roughly 13.8 billion years ago initiated the universe, and it has been expanding ever since. Scientists in 1998 disclosed that this expansion was actually accelerating, with an invisible force called dark energy as the hypothesised reason. Ordinary matter represents perhaps 5 per cent of the contents. Dark matter, known through its gravitational influences on galaxies and stars, may represent about 27 per cent. Dark energy may represent about 68 per cent.
Its mission is planned for five years, though the US space agency said the telescope may have enough fuel for five additional years. “It will be as if Hubble and James Webb kind of peered through a keyhole at the universe, while Nancy Grace Roman will kick the door down,” Nicola Fox, chief of NASA’s Science Mission Directorate, told reporters on Saturday. “Roman has broadly the same sensitivity and sharpness of vision as Hubble, but we survey the sky much faster,” Julie McEnery, Roman’s senior project scientist at NASA’s Goddard Space Flight Center in Maryland, told reporters at a briefing in July. McEnery said one month of Roman observations can survey our entire home galaxy. “One month of observations to survey our Milky Way galaxy would take about a century with Hubble,” McEnery said.
