NASA's TESS found a second
Earth-size world in the habitable zone of the TOI 700 system.

This planet, called TOI 700 e, is likely rocky and orbits
closer to the star than its sibling TOI 700 d,
another Earth-size planet.
These are distances from
the star where liquid water could exist under the right conditions.
Planet d is the conservative zone, where it is more likely
that both an Earth-like atmosphere and liquid water could exist.

This discovery emerged from TESS's second survey of the southern sky.
Scientists hope to find more of these
exciting new worlds in the ever-growing data from TESS.
