    👩🏽‍💻 I'm Dr. Becky Smethurst, an astrophysicist at the University of Oxford (Christ Church). I love making videos about science with an unnatural level of enthusiasm. I like to focus on how we know things, not just what we know. And especially, the things we still don't know. If you've ever wondered about something in space and couldn't find an answer online - you can ask me! My day job is to do research into how supermassive black holes can affect the galaxies that they live in. In particular, I look at whether the energy output from the disk of material orbiting around a growing supermassive black hole can stop a galaxy from forming stars.

    As someone who once worked as a spectroscopist, one of our greatest struggles is ascertaining how each stretch or peak corresponds to a particular molecule and nothing else. Many of these signals tend to overlap or translate downfield or upfield and it's actually unlikely that we can just "zero-in" on specific molecules that we want to observe. An atmosphere is basically a soup of molecules with each component possibly interfering with each other's signals. Sifting through this data is a daunting challenge especially since we cannot perform actual chemical analysis on the planet to confirm their identities.

      To quote George Carlin's Al Sleet (your hippy-dippy weatherman): "Don't forget, kids - behind every silver lining, there's a dark cloud!" It's been a good while for me, too, but (without looking it up), I seem to remember some of the gasses (CO2? H2O? Liquid H2O in clouds?) have some fairly lonely peaks. Again, it's been a while.
      I'm not terribly optimistic about red dwarfs, to be honest. I would think that a volatile compound with a high melting point (water, CO2) would vaporize on the hot side and eventually wander over to the perpetually dark side and freeze there for good. Or would that movement of mass from bright to dark possibly create a net torque on the planet in its star's gravitational field that would give it a spin strong enough to overcome any tidal forces in the rocks and molten core? I also seem to recall that there's a DNA analg that has another letter in rungs of its ladder. That particular configuration is too stable (again, from dim memory of the past) to work on Earth, where the molecule needs to be ripped apart and sewn together easily in order for terrestrial life to function, but maybe in the higher radiation environment of a red dwarf, some of the activation energy could be supplied? Just a WAG - ochem wasn't my thing.
      I guess at this point, I'd expect tidally locked planets with any potential ocean frozen forever on the dark side of the planet and nothing in the atmosphere but CO2 or noble gasses, maybe, on the hot, permanently lit side.
      But interesting none the less. And here's your weather report!

    Agreed. Red dwarves are notoriously unstable. Our sun, it turns out, is relatively quiescent. It rotates slowly, and the planet are much farther apart from each other than most of the solar systems we know of. And still earth is the only planet that has complex life forms on it.

      In matter of fact, we don't know if Earth is the only planets with complex life, we suppose there isn't life in the other planets, but as far as we know, we just spot a shadow in front of a star and make a lot of assumptions. One of the assumptions is that life has to emerge in an Earth like planet. But, why?. What is life?. A more stable scenario for life to emerge is a moon from a distant but large planet, really far from a star, energy would be taken by the heat of the gravitational forces between the planet and the moon. But how are we supposed to see those planets, we just see the shadows of nearby planets around the stars.

    Just because of the flaring issue, I never much liked M-class stars and never held out too much hope. Even if the very vast majority are incompatible, that still leaves a fair number just due to the fact that they're incredibly common. And there are always the more-comfortable and still very common K-class stars out there that tend to be a bit less temperamental. And our own G-class, of course, even if not so common.

Given their common volatility and how closely planets have to orbit them to be habitable, it seems almost a no brainer that they are unlikely to harbor life. I'm not saying it isn't worthwhile to study them and their planetary systems, but why anyone is hyped to find life around them is beyond me.

      A planet fit for humans?
      Exceedingly unlikely for two reasons:
      1. A 50% ice planet from the outer solar system, somehow came into our orbit and then crashed into us very very slowly...so that we didnt become another asteroid belt. Bringing water to a place where there's not supposed to be water.
      Also bringing an extra injection of iron to our core...which is why we have a magnetoshere protecting us.
      Brining us a moon that keeps our tilt stable.
      2. Life itself has terraformed Earth way more than most can imagine. E.g. Oxygen doesn't typically occur in armospheres (and if it does, it typically means that planet has been stripped of water).
      So an Earthlike planets can't exist without life to make it that way.
      It's exceedingly unlikely that there are spare planets out there. We need to take care of this one because it's likely the only one that habitable for earth-life.

It has the same sun but is 70% of the distance from the sun than the Earth is but it is much hotter.

      To calculate probability, you don't need a full sample.

      All I need is a small sample of sand to calculate what percentage is white and what percentage is black.

      1c on the other hand is about the same size of Venus and gets a little more sunlight, so finding out that it has less atmosphere than Mars(!) is newsworthy.

      If astronomers stopped studying Red dwarfs they'd be spending most of their time twiddling their thumbs simply because there aren't too many candidates of the other star type systems with planets, to study.
      Life on red dwarf planets is exceedingly unlikely...but learning anything new about any star system is still interesting af regardless. So if not, why not.
      Plus, we already learned a lot about our own solar system mostly from red dwarfs. (so it's useful).

      You could use Dayside as in "Dayside at the time of observation". But with the age and proximity, it's all but guaranteed to be tidally locked. Although I don't think we will get any direct evidence of that, as there is no real mechanism to test that. Aside from direct imaging, which is not in the cards until some mind-bending-sized space telescopes.

      The goldilocks zone around a red dwarf is very close to the star.
      Which is why goldilocks planets around red drawfs are typically tidally locked with the star.
      These planets have two extremes. One side is extremely hot, while the other side is extremely cold. If you average to two extremes, you end up with an average that is mild....e.g. 25°C.

If this were the case, that thin "habitable" zone on the planets surface wouldn't actually be very habitable.

      It's also possible to determine the density of a planet.
      The earth is the densist planet in our solar system. Mostly due to out unusually large iron core.
      If we find a very dense planet like our own, it might be a sign that it too has a relatively large iron core.

      Unless we know at what stage the Red dwarf is it's kind of putting the cart before the horse. The first thing we need to know is if the Red dwarf is that the beginning of its cycle or the end. These planets could have been sterilized by trappist-1 at the beginning of its red dwarf cycle. We're checking these planets after that oh, it will be a fruitless search. Granted I'm not an astrophysicist. If I'm wrong please let me know for future reference.

    I was under the impression that the Trappist system was more-or-less ruled out for having habitable planets because of how close-in all the planets were; There's a very high probability of the planets out to the edge of the habitable zone being tidally locked, which negates any other factors in their chance of harboring life
    All that is to say that I'm surprised they're spending any time looking at the system.
    (Also; temp+atmosphere models aren't always as you/she described, there are some very close-in hot jupiters (there's one I can't remember the name of, but it's like pitch black, blacker than coal) that's like 8,000 degrees despite having a very thick atmosphere..
