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!

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.

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.

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.

Thank You so much Young Lady I know we all had great hope and it is still early. In the first days of SETI I had a PC at home and I signed up to let them crunch numbers at night while I was not using it. I did that for years until it became a problem with security. But with this research i had not followed it close enough to fully understand it all your lectures shed light Infra red even on the topic and the charts were great too. Thank You for all your work. so glad you are able to share. Take care and keep chugging. Dennis in Virginia

If it has a decent atmosphere and especially hydrogen that hasn't been stripped away by the star, that would probably be a very good sign of a magnetosphere. 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.

♦I was expecting those results from the beginning. I am of different camp and look at biogenesis facts for what they are and not what I want them to be. You will never find any planets with life on them. Biogenesis chemistry is so incredibly complex. Even in the best labs it can't be reproduced. Time and randomization is not on Biogenesis side in the universe.

The orbits of the planets of the Trappist system is similar to the Galilean moons around Jupiter. The Trappist syste, is more spread out but the planet's masses are greater than the masses of the Galilean moons. Therefore, It wouldn't surprise me if the planetary orbits were in resonance causing internal heating of some planet, this is what happens to Io and Europa.

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.. I think it was called a puff-ball planet or something like that)

Dr. Becky, I'm a total civilian when it comes to astronomy, but I love the subject and how you explain it. I have a question from your video: You mentioned that we would expect Trappist-c to have a similar atmosphere to Venus because it receives similar amounts of light from its star as Venus. Since we really only have our own solar system as reference for other systems (at least through direct observation), this makes sense, but since Trappist is a red dwarf, doesn't that already make the composition of its system somewhat different? It has fewer atoms and molecules to build a system from, I would guess, but it's also blowing out a lot of its chemistry through radiation and solar flares and winds. Aren't red dwarfs composed of different atoms and molecules as well, or are they similar in composition to our sun, just less massive? They still "burn" the same elements?

Bob is diligently searching for something at a brightly illuminated street intersection. Alice inquires, "What are you searching for?" Bob admits, "I misplaced my ring." Alice queries further, "Where were you when you dropped it?" Bob points out, "At the opposite corner." Alice, puzzled, asks, "Then why are you scouring this area?" Bob answers, "This corner is better lit. The other side is practically invisible." This isn't an indictment of Bob's methods; rather, it's the best we can do with the tools we have. There have been significant improvements over time: initially, we could only spot planets as large as Jupiter in orbits as close as Mercury. Yet in essence, we're still playing the same game. Our detection capabilities are mostly limited to planets that transit or gravitationally perturb their host star. When we apply the requirement of the habitable zone, we are almost entirely left with red dwarfs due to their closer habitable zone. The habitable zone concept revolves around the presence of liquid water, a critical component for life. But if one thing is paramount to life, it's the relentless fight against entropy. Expose Earth to a stream of ultraviolet light, and eventually it will release a Tesla Roadster. The Earth, in essence, changes UV into IR, and this transformation results in local entropy reduction (as IR carries more entropy than UV per unit of energy). However, red dwarfs pose a problem as they emit a paucity of high-energy photons, particularly UV light. They have additional drawbacks, such as a propensity to strip any atmosphere off proximal planets. But in my view, the primary concern is the deficit of UV light. That's where our focus should be: stars similar to or brighter than our Sun. We should aim to discover Earth-like planets around 1AU. Unfortunately, these are largely undetectable with our current technology. So we continue searching in the 'brightly lit corner'. I don't think we're going to see anything until we start detecting planets in the habitable zone orbiting G-type stars.

Dr. Becky, I really appreciate your enthusiasm for objective science. Your treatment of the subjects of dark matter, black holes and the “crisis in cosmology” are excellent examples of this objectivity. The potential for new physics is exciting. I suppose this is why I am somewhat surprised by your excitement for the potential for finding habitable planets and disappointment with observations that indicate a planet is likely uninhabitable. The Kepler mission appears to indicate the latter is much more likely. This is a serious question: Why is finding an earth 2.0 so exciting to you as a scientist?

Many folks discount the value that earth is MOSTLY covered in... water. This must have HUGE effects on the atmoshere. Even locating extra-solar planets does not take into account the availability of oceanic water on those planets. Water is HUGE as far as life, as we know it, exists! Imaging extrasolar planet atmoshere cross-sections might help indicate the presence of huge water availability...
