![]() ![]() Parsing and understanding the information for discoveries and "lessons learned" is another. "Each one will have a unique signature, which we can use to determine the planet's mass and distance from its star." "With such a large number of stars and frequent observations, Roman's microlensing survey will see thousands of planetary events," Rachel Akeson, task lead for the Roman Science Support Center at the Infrared Processing and Analysis Center at the California Institute of Technology, said in a NASA statement. Numerous observatories on Earth have found their own planets or confirmed observations made by space telescopes, creating a larger community of exoplanet science that Roman will contribute to after its launch. ![]() ![]() Hubble, while not designed for planet-hunting since it launched just when discoveries were beginning, has done plenty of exoplanet science as well. Roman's efforts will build on other NASA missions optimized for planet-hunting, including the past Kepler mission that found thousands of exoplanets and the current Transiting Exoplanet Survey Satellite (TESS) looking for Earth-like planets close to us. NASA expects Roman to pick up more data than any of the agency's other astrophysics missions. Roman's microlensing capabilities will be coupled with a wide field of view that is 100 times larger than Hubble's, while capturing stars and planets with the same resolution as the famed telescope. ![]()
