NASA's TESS found a second

00:00:04,000 --> 00:00:08,000
Earth-size world in the habitable zone of the TOI 700 system.

00:00:12,000 --> 00:00:16,000
This planet, called TOI 700 e, is likely rocky and orbits

5
00:00:16,000 --> 00:00:20,000
closer to the star than its sibling TOI 700 d, 

6
00:00:20,000 --> 00:00:24,000
another Earth-size planet. 

7
00:00:24,000 --> 00:00:28,000
These are distances from

8
00:00:28,000 --> 00:00:32,000
the star where liquid water could exist under the right conditions. 

9
00:00:32,000 --> 00:00:36,000
Planet d is the conservative zone, where it is more likely 

10
00:00:36,000 --> 00:00:40,000
that both an Earth-like atmosphere and liquid water could exist.

00:00:44,000 --> 00:00:48,000
This discovery emerged from TESS's second survey of the southern sky. 

13
00:00:48,000 --> 00:00:52,000
Scientists hope to find more of these 

14
00:00:52,000 --> 00:00:56,000
exciting new worlds in the ever-growing data from TESS.
