Lee esta nota de prensa en español aquí. Our universe is filled with galaxies, in all directions as far as our instruments can see. Some researchers estimate that there are as many as two trillion galaxies in the observable universe. At first glance, these galaxies might appear to be randomly scattered across space, but they’re not. […]

NASA Announces Plan to Map Milky Way With Roman Space Telescope
NASA’s Nancy Grace Roman Space Telescope team has released detailed plans for a major survey that will reveal our home galaxy, the Milky Way, in unprecedented detail. In one month of observations spread across two years, the survey will unveil tens of billions of stars and explore previously uncharted structures. “The Galactic Plane Survey will […]
NASA’s Roman Observatory Passes Spate of Key Tests
NASA’s nearly complete Nancy Grace Roman Space Telescope has made another set of critical strides toward launch. This fall, the outer portion passed two tests — a shake test and an intense sound blast — to ensure its successful launch. The inner portion of the observatory underwent a major 65-day thermal vacuum test, showing that […]
NASA’s Roman Could Bring New Waves of Information on Galaxy’s Stars
Lee esta nota de prensa en español aqui. A team of researchers has confirmed stars ring loud and clear in a “key” that will harmonize well with the science goals and capabilities of NASA’s upcoming Nancy Grace Roman Space Telescope. Stars’ turbulent natures produce waves that cause fluctuations in their overall brightness. By studying these […]
NASA’s Tally of Planets Outside Our Solar System Reaches 6,000
The milestone highlights the accelerating rate of discoveries, just over three decades since the first exoplanets were found. The official number of exoplanets — planets outside our solar system — tracked by NASA has reached 6,000. Confirmed planets are added to the count on a rolling basis by scientists from around the world, so no […]
How NASA’s Roman Mission Will Unveil Our Home Galaxy Using Cosmic Dust
NASA’s Nancy Grace Roman Space Telescope will help scientists better understand our Milky Way galaxy’s less sparkly components — gas and dust strewn between stars, known as the interstellar medium. One of Roman’s major observing programs, called the Galactic Plane Survey, will peer through our galaxy to its most distant edge, mapping roughly 20 billion […]
Ami Choi: Unraveling the Invisible Universe
Research Astrophysicist and Roman’s Deputy Wide Field Instrument Scientist – Goddard Space Flight Center From a young age, Ami Choi — now a research astrophysicist at NASA — was drawn to the vast and mysterious. By the fifth grade, she had narrowed her sights to two career paths: marine biology or astrophysics. “I’ve always been […]
Katie Bisci: Resourcing for Big Science
Deputy Project Manager for Resources – Goddard Space Flight Center How are you helping set the stage for the Roman mission? I’m a deputy project manager for resources on the Nancy Grace Roman Space Telescope team, sharing the role with Kris Steeley. Together, we oversee the business team, finance, outreach, scheduling, and more. I focus […]
NASA Test Deploys Roman Space Telescope Solar Panels, ‘Visor’
On Aug. 7 and 8, NASA’s Nancy Grace Roman Space Telescope team assessed the observatory’s solar panels and a visor-like sunshade called the deployable aperture cover — two components that will be stowed for launch and unfold in space. Engineers confirmed their successful operation during a closely monitored sequence in simulated space-like conditions. On the […]
NASA Roman Core Survey Will Trace Cosmic Expansion Over Time
NASA’s Nancy Grace Roman Space Telescope will be a discovery machine, thanks to its wide field of view and resulting torrent of data. Scheduled to launch no later than May 2027, with the team working toward launch as early as fall 2026, its near-infrared Wide Field Instrument will capture an area 200 times larger than […]
