00:00NASA-backed astronomers have confirmed the youngest known exoplanet ever observed.
00:05Called Elias 224b, the planet is less than 1 million years old.
00:09It has roughly the mass of Jupiter and lies about 450 light-years from Earth.
00:15The young world is still embedded in a disk of gas and dust around its star.
00:20Researchers found it inside a prominent gap in that disk,
00:23where planets can carve paths through surrounding material.
00:26The planet is also about 55 times farther from its star than Earth is from the Sun.
00:31That distance and its extreme youth challenge existing planet formation models.
00:36Scientists confirmed the planet using observations from multiple telescopes,
00:41including Keck data from 2018 and 2020.
00:45NASA's newly launched Roman Space Telescope could soon detect more young worlds like it.
00:50These discoveries may help astronomers better understand how giant planets form.
