Roman Space Telescope Selects 24 Flight-quality Heat-vision 'Eyes'

Jun 9, 2021 - Roman's team recently flight-certified all 24 of the detectors the mission needs. When Roman launches in the mid-2020s, these devices will convert starlight into electrical signals, which will then be decoded into 300-megapixel images of large patches of the sky. These images will allow astronomers to explore a vast array of celestial objects and phenomena, bringing us closer to solving many pressing cosmic mysteries.

NASA’s Roman Mission to Probe Cosmic Secrets Using Exploding Stars

May 26, 2021 - Roman’s supernova survey will help clear up clashing measurements of how fast the universe is currently expanding, and even provide a new way to probe the distribution of dark matter, which is detectable only through its gravitational effects. One of the mission’s primary science goals involves using supernovae to help pin down the nature of dark energy – the unexplained cosmic pressure that’s speeding up the expansion of the universe.

How NASA’s Roman Space Telescope Will Uncover Lonesome Black Holes

Apr 13, 2021 - NASA’s Nancy Grace Roman Space Telescope will provide an unprecedented window into the infrared universe when it launches in the mid-2020s. One of the mission’s planned surveys will use a quirk of gravity to reveal thousands of new planets beyond our solar system.

NASA's Roman Mission Predicted to Find 100,000 Transiting Planets

Mar 31, 2021 - NASA's Nancy Grace Roman Space Telescope will create enormous cosmic panoramas, helping us answer questions about the evolution of our universe. Astronomers also expect the mission to find thousands of planets using two different techniques as it surveys a wide range of stars in the Milky Way.

New ‘Eyewear’ to Deepen the View of NASA’s Roman Space Telescope

Mar 3, 2021 - NASA’s Nancy Grace Roman Space Telescope will be able to explore even more cosmic questions, thanks to a new near-infrared filter. The upgrade will allow the observatory to see longer wavelengths of light, opening up exciting new opportunities for discoveries from the edge of our solar system to the farthest reaches of space.

NASA's Roman Mission Will Probe Galaxy’s Core for Hot Jupiters, Brown Dwarfs

Jan 25, 2021 - When it launches in the mid-2020s, NASA’s Nancy Grace Roman Space Telescope will explore an expansive range of infrared astrophysics topics. One eagerly anticipated survey will use a gravitational effect called microlensing to reveal thousands of worlds that are similar to the planets in our solar system. Now, a new study shows that the same survey will also unveil more extreme planets and planet-like bodies in the heart of the Milky Way galaxy, thanks to their gravitational tug on the stars they orbit.

Roman Space Telescope Could Image 100 Hubble Ultra Deep Fields at Once

Jan 11, 2021 - Roman will be able to photograph an area of the sky at least 100 times larger than Hubble with the same crisp sharpness. Among the many observations that will be enabled by this wide view of the cosmos, astronomers are considering the possibility and scientific potential of a Roman Space Telescope "ultra-deep field." Such an observation could reveal new insights into subjects ranging from star formation during the universe’s youth to the way galaxies cluster together in space.
