NASA’s Roman Space Telescope could uncover oodles of potentially Earth-like exoplanets during its survey of our galaxy’s central, star-packed bulge. But astronomers probably won’t be able to learn much more about most of them. spklr.io/6018ErrQ4

NASA’s Roman Space Telescope could find alien Earths—but not like you think

The Roman Space Telescope will spend more than a quarter of its time staring at the Milky Way’s bulge, a star-packed central region of our galaxy that may swarm with small, rocky exoplanets

What's so cool about the Roman Coronagraph? Well, it's the first *active* coronagraph in space, meaning that it can adjust itself on the fly to help scientists get the clearest glare-free images. The @NASARoman Space Telescope is set to launch on Sunday, Aug. 30!

Bring a bit of the cosmos into your space @NASARoman is set to investigate some of the biggest questions in astrophysics, from how the universe evolved to how common planets are beyond our solar system. Celebrate its upcoming launch by bringing Roman into your own space: go.nasa.gov/4qEQJOM
Stylized poster featuring the Nancy Grace Roman Space Telescope emerging from an open book, as if rising from its pages. The telescope is centered against a deep blue cosmic background with vertical beams of glowing light and swirling orbital paths encircling it. Small spacecraft and nebula-like elements float around the telescope, giving a sense of motion and discovery. At the top left is the NASA logo and “National Aeronautics and Space Administration.” At the bottom, bold text reads: “Nancy Grace Roman Space Telescope,” with “nasa.gov” in small type underneath.

NASA’s Nancy Grace Roman Space Telescope will help scientists investigate dark energy and dark matter, discover and characterize exoplanets, map billions of galaxies, study black holes, and explore objects from our own @NASASolarSystem to the edge of the observable universe. Liftoff is targeted for no earlier than 7:26 a.m. EDT Sunday, Aug. 30. Learn where to watch: nasa.gov/live
