What to know

  • NASA's Roman Space Telescope launched August 30, 2026, and will detect exoplanets by monitoring hundreds of millions of stars for gravitational microlensing effects—temporary brightness spikes when one star's gravity magnifies light from a distant star behind it.
  • The technique can reveal planets orbiting foreground stars even when the planets themselves are too faint to observe directly, by measuring subtle disturbances in the lensing brightness pattern.
  • Roman's Galactic Bulge Time-Domain Survey will observe six fields toward the Milky Way's center roughly every 12 minutes over six observing seasons, with NASA expecting to discover more than 1,000 planets.

“According to Einstein's theory of general relativity, an object's mass curves the space around it. Light traveling through that curved space also follows a curved path.”

    Roman's Galactic Bulge survey to target crowded Milky Way center

    As part of its Galactic Bulge Time-Domain Survey, Roman will repeatedly observe six fields toward the Milky Way's center, monitoring hundreds of millions of stars roughly once every 12 minutes across six observing seasons, with NASA expecting discovery of more than 1,000 planets.

    “Microlensing is exciting because it functions as a tool that can help astronomers find planets that are difficult to find in other ways.”

      How do you find a planet you can’t see? NASA’s new Roman Space Telescope will watch hundreds of millions of stars for tiny changes in brightness, using gravity as a magnifying glass to uncover distant planets hiding in our galaxy. https:// theconversation.com/nasas-roma…

    Roman's gravitational microlensing method explained

    Research Associate Professor Thomas Fauchez of American University details how Roman will use gravitational microlensing to detect exoplanets without directly seeing them, by monitoring hundreds of millions of stars for temporary brightness changes caused by foreground stars' gravity bending light from background stars.

    “It is like looking though a magnifying glass, except there is no glass. The lens is gravity itself.”
