Very interesting. The habitable zone a idea taken from an Intelligent Design book/video, the Privileged Planet. However, there a a great number of other factors needed to come close to the Earth as a planet that can support life.

Just exactly WHAT are you talking about??

A SciFi movie??

The scientists call Earth, in the Goldilocks Zone ..not too hot...not too cold

I don’t see what ID has to do with any of it.

You’re absolutely right.

The habitable zone of red dwarf stars is so close to the stellar body that planets occupying this area are almost invariably tidally-locked and have a single face toward the sun. This in and of itself makes the planet unlikely to be habitable because massive temperature differences between the light and dark sides create tremendous winds as the atmosphere (if there even is one) stuggles to find temperature equilibrium.

Further, a tidally-locked planet is unlikely to have sufficient magenetic field due to a hugely diminished dyanamo effect to prevent the solar wind from stripping any atmostphere to begin with.

I suspect no matter what the hype, this planet at the very best is no more inviting than Mars. It is certainly not another Earth.

Too bad...A planet able to sustain humanity orbiting a red dwarf would be a huge insurance policy against extinction because they’ll burn for trillions of years. Our sun will be too brige for our oceans to remain liquid in mere hundreds of millions.
