00:0032 years ago, the first exoplanet was discovered, and today we know of 6,000.
00:06Exoplanets are worlds orbiting other stars, and most are nothing like Earth.
00:10TOI 561b is a rocky planet where a year lasts just 10 and a half hours, and it's so close
00:16to its star, temperatures hit 3,600 degrees Fahrenheit.
00:20That's hot enough to melt rocks into lava oceans.
00:23Then there's PSRJ23222650b, a planet orbiting a pulsar, the dead remains of an exploded star.
00:32And extreme gravity stretches it into a lemon-like shape.
00:35It's one of the lightest planets ever discovered.
00:39WASP 43b has some of the wildest weather in the universe.
00:42It's tidally locked, with permanent day and night, and dayside temperatures near 3,000
00:47degrees, driving hurricane-force winds across the planet.
00:51And K218b is one of the most intriguing finds yet.
00:55It's a super-Earth, or mini-Neptune, in the habitable zone, with water vapor and carbon-based
01:01molecules detected in its atmosphere, making it a major target for the search for life.
01:06Finally, TRAPPIST-1e may be the most Earth-like.
01:09It's rocky, Earth-sized, and orbits a nearby red dwarf star where liquid water could exist.
01:15And we're just getting started.
01:17NASA's Nancy Grace Roman Space Telescope could uncover thousands more alien worlds very soon.
