Earth-Size Planet Found In TOI 700 System's Habitable Zone
NASA’s Transiting Exoplanet Survey Satellite (TESS) has been used to discover Earth-size planet TOI 700 e. It is "orbiting within the habitable zone of its star – the range of distances where liquid water could occur on a planet’s surface," according to NASA's Goddard Space Flight Center.
The TOI 700 system is about 100 light-years away.

00:00 NASA's TESS found a second Earth-sized world in the habitable zone of the TOI 700 system.
00:11 This planet, called TOI 700 e, is likely rocky and orbits closer to the star than its sibling
00:17 TOI 700 d, another Earth-sized planet.
00:23 Planet e orbits within the star's optimistic habitable zone.
00:26 These are distances from the star where liquid water could exist under the right conditions.
00:33 Planet d is in the conservative zone, where it is more likely that both an Earth-like
00:37 atmosphere and liquid water could exist.
00:42 This discovery emerged from TESS's second survey of the southern sky.
00:49 Scientists hope to find more of these exciting new worlds in the ever-growing data from TESS.
