00:01NASA's TESS found a second Earth-sized world in the habitable zone of the TOI-700 system.
00:10This planet, called TOI-700E, is likely rocky and orbits closer to the star than its sibling TOI-700D, another
00:20Earth-sized planet.
00:22Planet E orbits within the star's optimistic habitable zone.
00:26These are distances from the star where liquid water could exist under the right conditions.
00:32Planet D is in the conservative zone, where it is more likely that both an Earth-like atmosphere and liquid
00:39water could exist.
00:42This discovery emerged from TESS's second survey of the southern sky.
00:49Scientists hope to find more of these exciting new worlds in the ever-growing data from TESS.
