Earth-sized habitable zone planet found 300 light-years away

Researchers have discovered a new Earth-sized planet orbiting a star outside our solar system. The planet, called Kepler-1649c, is around 1.06 times larger than Earth. It’s also quite close to its star, orbiting at a distance that means it gets around 75% of the light Earth does from the Sun. The planet’s star is a red dwarf. It orbits so closely to its star that one year is just 19.5 of our days.

I am very skeptical that any planet around a red dwarf star is going to be that habitable. It is almost certainly tidal-locked to its star, just like the Moon is with the Earth, meaning that one side of the planet will always face the star and likely be too hot. And the far side will never get any of the light, therefore it's going to be freezing cold, far worse than any place on Earth. MAYBE the boundaries between those two sides would be habitable. MAYBE. Any life on that planet is going to have been blasted to extinction from the stellar flares from the red dwarf; they are known for this, and the planet would be orbiting very close, such that any flare would very likely sterilize the place of life.
