"Super-Earth" planet TOI-715b discovered 137 light years away in habitable zone by TESS satellite

 1.55 times wider than Earth, orbits small red dwarf star every 19 day

 Located in conservative habitable zone, possible liquid water if conditions allow

2nd Earth-sized planet may also exist in same system

Red dwarfs prime targets, host many small rocky worlds w/ potential to be habitable

 Upcoming telescopes like James Webb can study atmospheres of planets like TOI-715b

Signs of atmosphere, clouds, CO2 would indicate if super-Earth is really habitable

Exact conditions for life still unknown but will study all intriguing habitable zone planet

 TOI-715b adds to catalog of worlds for follow-up observation by future mission

 Goals: Find true Earth twin, prepare for probes to habitable planets one day
