NASA's Nancy Grace Roman Space Telescope is nearing launch, designed to survey vast areas of the sky to study dark matter, dark energy, and exoplanets.
Key facts
- •The Roman telescope is scheduled to begin science operations in January 2027.
- •The mission's Wide Field Instrument can image an area 100 times larger than Hubble's cameras.
- •The University of Arizona is leading nine NASA-approved investigations using Roman data.
- •The Coronagraph Instrument will enable direct imaging of exoplanets by suppressing starlight glare.
- •The NASA Roman Project awarded $800,000 to the University of Arizona for high-performance computing resources.
NASA's Nancy Grace Roman Space Telescope is two days from launch, marking the agency's next flagship astrophysics mission following the James Webb Space Telescope. Science operations are expected to begin in January 2027. University of Arizona faculty and students are among those preparing to utilize the telescope's wide-field imaging capabilities to study the universe.
By the numbers
Wide-Field Survey Capabilities
The Roman telescope features a 7.9-foot primary mirror and is designed to survey the sky at a scale 100 times larger than the Hubble Space Telescope while maintaining similar sensitivity. While Hubble has observed approximately 0.1% of the night sky over 30 years, Roman has the potential to survey the entire sky at the same resolution.
Dark Matter and Dark Energy Research
A primary goal for the mission is investigating dark matter and dark energy. The University of Arizona's Arizona Cosmology Lab has been selected to support these efforts, including a project focused on kinematic lensing. Researchers plan to combine Roman's images with spectroscopic measurements to analyze the structure and evolution of the universe with high precision.
Exoplanet Imaging with Coronagraphy
Roman’s Coronagraph Instrument will block starlight to allow for the direct imaging of exoplanets. The instrument is designed to detect planets 100 million times fainter than their host stars, performing 100 to 1,000 times better than existing space-based coronagraphs. This technology serves as a pathfinder for the proposed Habitable Worlds Observatory.
