Hi Anton, it was only found out in 1965 that Mercury is actually not(!) 1:1 tidally locked to the sun, but rather has 3:2 tidal locking, meaning that its surface does rotate relative to the sun - the problem is that mercury's own orbital resonance with venus and earth makes it so that the two easiest times to observe mercury from Earth creates the illusion that the same side of mercury is always facing the Sol, which is not the case. It was not until mercury was able to be observed with a radio telescope that they could easily observe its rotational motion relative to its orbit around the sun. Thus its all that much more impressive that there are permanently dark areas on mercury able to house ice.

[@NullHand]

Cool! Or Hot I guess. Is the rotation of Mercury locked to Venus by chance? Or is it still spinning down to 1:1 lock with Sol?

[@shinystarmiestudios4179]

Venus is almost tidally locked to the sun. It's barely outside the target locking range.

[@WarwickAllison]

​@@NullHand Neither. The 3:2 resonance is local minima, probably enforced by Mercury's unusually high orbital eccentricity.

[@Near_Void]

​@@NullHand some parts of mercury get really cold because of crater rim shadows

[@rhoddryice5412]

I think it's quite probable that most planets close to its star with an eccentricity bigger than 0.15 is in an rotation/orbital resonance other than 1:1. Other properties are axial tilt and inclination. Add this together and a day night cycle might be rather common. I watched a talk about this not long ago.

[@shinygalaxy8837]

Amazing videos as always! Models may support TRAPPIST 1b not having an atmosphere, but hopefully, d, e, or f show signs of an atmosphere. Though if that is not the case, then at least we would still have a greater understanding of how planets around M-type main-sequence stars typically function. Love the JWST, and thank you for reporting on the wonderful updates! Habitability around ultra-cool dwarfs, such as very low mass M-type main-sequence stars and L-type main-sequence stars fascinates me.

Not really surprising, as the b planet (scaled up to our solar system) is closer to its sun than Venus. It remains to see if the others are possible candidates. The TRAPPIST-1 system is just one of many systems and even if the other 6 (even d and e) don't have life on them, this is just one of many system. Good to learn about exoplanet systems, this is still an important discovery and a victory for our understanding of exoplanets.

Room temperature but in a vacuum so liquid water would not be possible there, maybe beneath an ice shell on the dark side where the pressure is higher.

[@danoblue]

It seems like flare stars are inimical to their planetary system's chances for life. I understand that not all red dwarfs are flare stars, however, so the possibility is still there that some red dwarfs may at least have planets with atmospheres. Whether or not these planets can develop life, especially given the type of sunlight involved, is yet to be determined. But JWST is certainly going to help us understand exoplanets a lot more, and that is a giant step forward in our search for extraterrestrial life. Nice video, Anton.

[@Damian-cilr2]

we cannot fully rule red dwarfs out yet,and take this with a grain of salt,bwcause of the small sample size of the study,and of course because our knowledge of the universe is still very limited,but the stronger stellar flares seemingly come from higher latitudes,closer to the poles than the equator.

Genius! I love the idea of using background starlight as a comparison with light coming from a celestial object. In this case, the planet is hot, so the contrast is strong, perhaps too obvious, however JWST is super sensitive and could be used to scan cooler objects, surely. What if we were to look at a few cold bodies that we know more about such as our own outer planets? For instance, Pluto, being much less cold than it ought to be, to give comparative data. It's very helpful, confirming that red dwarf systems, tempting though they are, will be a waste of energy as they will probably not host planets supporting life. Maybe it's harder identifying the planets around G type stars (more glare, less wobble etc.) we just have to get better at looking😕

Even hundreds of years like great wall of China or the pyramids. One last help in this regard might come from medical science. Human lifespans might increase drastically over the next few hundred years. Even right now we have been successfully able to reverse aging in mice, in Sinclair's tests. So its is not very farfetched that in either a few decades to maybe a few hundred years humans might be able to radically increase our lifespans.

But trappist 1b is the closest to its star.

[@footyball66]

why are they looking at this one.... look at D E F G...... for gods sake! they are the ones in the habitable zone.

No planet escapes JWSTs gaze!

We should focus on G and K stars - not M stars. M stars send out more radiation and solar flares, wiping out the atmosphere and the planets would be tidally locked.

[@matthewjohns1758]

Are all planets of M Stars tidally locked?

[@richardcarlin1332]

@@matthewjohns1758 Think of the planets as similar to the moons of Jupiter. An M star is on average 84 times more massive than Jupiter - but similar in size, so yes M star planets are all tidally locked. In our solar system, Mercury is tidally locked, and I think Venus might be as well. Earth is far enough away to not be tidally locked.

[@olencone4005]

@@richardcarlin1332 Actually, neither Mercury nor Venus are tidally locked -- Mercury has a 3:2 resonance with the Sun, so it rotates 1.5 times each orbit. And Venus has a slightly longer "day" than it has a "year," taking 225 Earth-days to complete one orbit of the Sun, and 243 Earth-days to complete one rotation on its axis.

I suspect the planets would be baren of atmosphere per the solar flares but let's study more and get a good datapoint.

[@Alondro77]

Several of the planets MUST have thick atmospheres and water, because their density is too low for them to be solid rock at their size. 1b is similar to Earth's density, and thus could indeed be a barren rock blasted free of an atmosphere due to its roastingly hot proximity to the star. These planets formed pretty much where they are right now, most likely. It's almost impossible for their tight orbits to have remained stable if they'd migrated at all, so 1b has been sitting there being fried from intense radiation from the start. It's likely the material that went into its formation was already stripped of lighter elements.

I'm not surprised that Trappist-1b is barren. If d and e turn out to be barren, I'll be heartbroken. It would be evidence that habitable planets are extremely rare in the universe.

[@johnchristopherrobert1839]

The viewer should be reminded that mercury is not tidily locked. It has six days to every mercury year.

[@Thedeepseanomad]

Imagine the sweetness of discovering a system with multiple habitable planets within colonization distance.

[@Poodleinacan]

We are inching closer to knowing if life possibly resides on on of these planets.

[@WilliamFord972]

I love this telescope.

If Trappist ales are so good on Earth, just imagine how good they must be in the Trappist home system…
