00:00To do this, Roman will observe about 200 million stars in the dense center of our Milky Way
00:06every 15 minutes over the course of years. The prospect is breathtaking. Roman is expected to
00:14capture around 27,000 of these microlensing events, finding an estimated 1,400 to 2,600
00:23new planets in the process, down to worlds with a mass of Mars. The exciting thing is, Roman finds
00:31precisely the kind of planets that all previous missions have missed, namely cold planets in wide
00:39orbits far out in their systems. And it gets even better. Roman will also track down hundreds to
00:47possibly around 1,000 so-called rogue planets. Worlds without any star at all. Floating all alone
00:55through the darkness between the stars.
