i think this article is very interesting and important to society so the people know what going on.

Most super earths are larger, possibly with larger iron cores and combined with a thick Venus like atmosphere maybe life is possible at the farthest edge of the goldilocks zone…

I agree with your statement, but not your upside down US flag.

Huge complex data factors about Sun and Earth are extremely unique with probability of zero to form without intelligent power outside our dimension. We shouldn’t be here, yet here we are.

Maybe it will take a higher greenhouse gas content to push the edge of the habitable zone out to where the solar winds are not too violent. Would be nice if the heliopause is not close enough to frequently get compressed until a prospect planet is exposed to the full blast of cosmic rays too. I guess this is just further evidence that long term habitability is no trivial issue; a lot of ways things can go wrong.

If these close orbiting planets are tidally locked, one would suspect that all the volatiles will have condensed upon the cold unlit side — those which were not stripped off by the stellar winds.

Water covered planets could well have oceanic life with water shielding it like on the severe radiation environment of Europa.

Well there goes the Type I or the Type II’s for those stars. I can’t remember they were guessing( educated of course ) about what was it 50% of them might have planets? So a huge number of Goes flipped to the No Go side. So where will we find the other Folks in the night sky? But the big Jovian like Planets have their own Space noise and even maybe thier own killer space weather locally. I have this feeling that we might be the only ones out here in the space lanes, but even if we aren’t Till we get to the point of not trying to kill ourselves off, and can get to space further than our own solar system it might not matter. Is there anyone out there, the song lines go

jovian planets have big magnetosphere which can protect there moons hence it doesnt really matter.
