HubbleSite Posted January 5, 2020 Posted January 5, 2020 NASA's upcoming Wide Field Infrared Survey Telescope (WFIRST), scheduled for launch in the mid-2020s, will have the power to survey the sky 1,000 times faster than the Hubble Space Telescope, with Hubble-quality detail, in the near-infrared. A simulated image of a 34,000-light-year swath across our neighboring galaxy Andromeda showcases WFIRST’s unique detector configuration, expansive field of view and high resolution. The image was generated using data collected by Hubble, and shows the red and infrared light of more than 50 million individual stars in Andromeda, as they would appear with WFIRST. WFIRST is designed to address key questions across a wide range of topics, including dark energy, exoplanets, and general astrophysics spanning from our solar system to the most distant galaxies in the observable universe. WFIRST is expected to amass more than 4 petabytes of information per year, all of which will be non-proprietary and immediately accessible to the public. The simulated image, which represents the staggering amount of data that could be captured in a single pointing over just 90 minutes, demonstrates the power of WFIRST for examining large-scale structures that are otherwise too time-consuming to image. Astronomers are currently using simulations like this to plan future observations. View the full article Quote
