Roman also carries a “coronagraph” for blocking the light of individual stars, which could help discover 40 times as many exoplanets as have been detected so far — as @jennaahart.bsky.social explains here www.nature.com/articles/d41...

The Roman telescope is about to take planet-hunting to the next level
NASA’s Nancy Grace Roman Space Telescope, set to launch shortly, could find 40 times the number of distant worlds that have been detected so far.

More context on this #Artemis II image: * This is the night side, lit by moonlight. You can see city lights in Spain & Portugal, & a sliver of day at lower right * The Sun is entirely behind Earth, which makes it a kind of solar eclipse, but w/ Earth doing the eclipsing instead of the Moon: ☀️🌍🚀🌕
A full disc image of Earth, as seen from the Orion Crew Module. The planet is a pale blue, swirling with white clouds and glowing slightly lighter blue in place from reflected light. At lower left, a large brown landmass is Africa, with Spain and Portugal with twinkling lights where the planet curves. At top right, auroras glow in a thin green glow, just barely separated from the planet's surface. Earth is set against the black of space (pic: NASA/R.Wiseman)
