Trying to see an exoplanet is like spotting a firefly next to a lighthouse from thousands of miles away. This video explains how the Roman Coronagraph solves this problem, paving the way for us to study the atmospheres of other worlds and search for habitable planets.

00:00Could you photograph an exoplanet?
00:03I'm here in Florida to see NASA's Nancy Grace Roman Space Telescope launch.
00:08And on board this telescope is one of the coolest pieces of technology, the coronagraph.
00:13Now, coronagraphs allow us to look directly at planets orbiting other stars, or exoplanets.
00:19Now, to try to see a planet around another star is incredibly difficult.
00:23It's like trying to see a firefly next to a lighthouse thousands of miles away.
00:28The star is going to be too bright to see anything in its orbit.
00:32So what a coronagraph does is it blocks the light of the star,
00:36allowing the much fainter light of the planets in its orbit to come into view.
00:40Now, the Roman coronagraph is perhaps the most advanced coronagraph ever designed,
00:45and it will allow us to directly look at other worlds across the cosmos,
00:49investigating different types of planets and atmospheres.
00:53This technology demonstration will show us how this tech works in space.
00:57And if successful, the Roman coronagraph will pave the way toward one day finding
01:02and studying planets that we might even call habitable.
01:05So follow along as the Roman Space Telescope launches this weekend,
01:10and we send this amazing tech out into space.
