North Korean Flair:

ALL THESE PLANETS ARE CLOSER TO THEIR STAR THAN MERCURY IS TO OURS.....................SEE BOTTOM PIC...............
EXOPLANET PING!...................
OOOOOOR, they could not.
Of course water could be common. Hydrogen is the most common element in the universe and oxygen is the third most common element in the universe so who could be stupid enough to think that it is rare anywhere but here. Water will be water here, on Jupiter’s moons, in comets, so by extrapolation how far do you have to go before water isn’t there anymore? And since carbon is the fourth most common element in the universe, it stands to reason that carbon dioxide and methane will be very common as well.
Planet Earth has earthlings.
Planet Mars would have martians.
Planet e has......eepers?
Mars Needs Women.
It says they’re tidally locked such that you have a permanent hot side and a permanent cold side. But you also have permanent shadow zones. Where you could grow barley. And hops. Yes. This could be the mythical Planet Of Beer.
And another thing, planets are not internally heated by tidal forces, they are heated by decay of unstable heavy elements.
Don’t we all.
Trappist 1 is an ultra cool red dwarf of about 0.09 solar masses, just a bit over the minimum for a proton-proton reaction, and a surface temperature of about 2500K.
Since this is a red dwarf, it can have the tendency to flare frequently. Not being a physicist or cosmologist (I’m just an engineer), I suspect that low mass stars that are fully convective may also tend to do a good amount of flaring.
North Korean Flair:
these jackwagons, always with the “could”s and “may”s.
Please give us some real science.
Nobody needs that movie.
I figured that when I saw how short their orbital periods were in the other chart.
They could be wrong, though.
For decades they told us Mercury was ‘tidally locked’ and only one side faced the Sun, then they found out they were wrong. It turns, slowly, but it turns.....................
Wouldn’t that tidal locking create a massive thermal differential, and result in hurricane winds?
If there’s an atmosphere................
“Hydrogen is the most common element in the universe and oxygen is the third most common element in the universe so who could be stupid enough to think that it is rare anywhere but here. “
The facts you mention while suggesting conditions for combining hydrogen and oxygen into water may exist with exo-planets in other solar systems, it is that combining of the two elements, and the conditions for it, which may NOT BE so abundant in the universe. If the mere existence of how much hydrogen and oxygen go to make up the known gases in the universe was the COMMON AND ESSENTIAL ingredient for estimating how often water “ought to be” present, then it would certainly be more present even in our own solar system than empirical science has determined so far.
Just take our own planet and what is described as key factors that make its ability to contain water - distance from our star and other factors, yet scientists still debate whether water was present in what went to make up the earth from the solar disk, or if it arrived early in the course of earth history from asteroids and other bodies that pelted the early earth. And none of the scientists on either side of that debate argue that water is here merely because of how “common” are hydrogen and oxygen.
Sure a lot of assumptions in this article.
