NASA’s Roman Mission Gets Cosmic ‘Sneak Peek’ From Supercomputers

NeRD

Researchers are diving into a synthetic universe to help us better understand the real one. Using supercomputers at the U.S. DOE’s (Department of Energy’s) Argonne National Laboratory in Illinois, scientists have created nearly 4 million simulated images depicting the cosmos as NASA’s Nancy Grace Roman Space Telescope and the Vera C. Rubin Observatory, jointly funded by NSF (the National Science Foundation) and DOE, in Chile will see it. Michael Troxel, an associate professor of physics at Duke University in Durham, North Carolina, led the simulation campaign as part of a…

What is Dark Energy? Inside our accelerating, expanding Universe

NeRD

11 min read What is Dark Energy? Inside our accelerating, expanding Universe Some 13.8 billion years ago, the universe began with a rapid expansion we call the big bang. After this initial expansion, which lasted a fraction of a second, gravity started to slow the universe down. But the cosmos wouldn’t stay this way. Nine billion years after the universe began, its expansion started to speed up, driven by an unknown force that scientists have named dark energy. But what exactly is dark energy? The short answer is: We don’t…

NASA Puts Next-Gen Exoplanet-Imaging Technology to the Test

NeRD

6 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) JPL scientist Vanessa Bailey stands behind the Nancy Grace Roman Coronagraph , which has been undergoing testing at JPL. About the size of a baby grand piano, the Coronagraph is designed to block starlight and allow scientists to see the faint light from planets outside our solar system. A cutting-edge tool to view planets outside our solar system has passed two key tests ahead of its launch as part of the agency’s Roman Space Telescope by 2027. The Coronagraph…

Meet the Infrared Telescopes That Paved the Way for NASA’s Webb

NeRD

Scientists have been studying the universe with infrared space telescopes for 40 years, including these NASA missions, from left: the Infrared Astronomical Satellite (IRAS), launched in 1983; the Spitzer Space Telescope, launched in 2003; and the James Webb Space Telescope, launched in 2021. NASA/JPL-Caltech The Webb telescope has opened a new window onto the universe, but it builds on missions going back 40 years, including Spitzer and the Infrared Astronomical Satellite. On Dec. 25, NASA will celebrate the two-year launch anniversary of the James Webb Space Telescope – the largest…

NASA’s Roman Mission Gears Up for a Torrent of Future Data

NeRD

NASA’s Nancy Grace Roman Space Telescope team is exploring ways to support community efforts that will prepare for the deluge of data the mission will return. Recently selected infrastructure teams will serve a vital role in the preliminary work by creating simulations, scouting the skies with other telescopes, calibrating Roman’s components, and much more. Their work will complement additional efforts by other teams and individuals around the world, who will join forces to maximize Roman’s scientific potential. The goal is to ensure that, when the mission launches by May 2027,…
