@garethdean6382 7 лет назад

'For a century we focused on reaching the wandering star, our entire civilization, its politics, its religion, its culture, focused to a single goal, breaking the bonds of gravity and ascending to the heavens. The pace of discovery went from a crawl to a sprint as we urged ourselves ever onwards. It took time, such time, three generations passed who saw their lives end before their dreams, but eventually came the day when the Ark was ready. We crewed it with our best and brightest, our ambassadors to the heavens who would take a powerful message from our world to the skies. After many, so many failures we cheered as we saw the Ark rise atop a pillar of flame. We sat enthralled as the grainy signal played on monitors across the globe, as our world shrank to a dot and our destination grew large. United as a people, billions as one voice, one mind, one dream we rose in exultation as the Ark landed on a new world and those who represented us strode forth. Our high priest was the first to deliver his message; 'We have passed your test oh Lords, let us now all ascend to the heavens with you to live forever in paradise. 'But are YOU not the messengers from the skies?' the angels replied. The orbital bombardment started soon after.

A significant thing about finding Trappist-1's planetary system is that the odds that the "ecliptic" of a system of exoplanets is oriented in such a way that the planets in the star's habitable zone will transit the star's disk, as seen from Earth, is only about one percent. That means for every nifty thing we discover by the transit method, there are probably 100 other equally nifty things that we can't discover by that method because the planets' orbits don't cross their star's disk from our vantage point. Yet we found Trappist-1's planets. That means there are probably a lot more red dwarf stars like it out there.

@pbsspacetime 7 лет назад

This is a really important point! It's why we can extrapolate from the Kepler data that most stars have planetary systems, and that at least ~half have "Goldilocks" planets.

Not true, for example there are lakes of hydrocarbons on Saturns moon Titan. It's so cold out there that water is hard as rock (frozen), but it's the right temperature for stuff like ethanol and methane to be liquid. There's more gasoline on Titan than there are oil reserves on Earth, and apparently the stuff even rains from sky from time to time.

@solanofelicio 7 лет назад

I didn't think seeing other planets as large as the moon on the sky was possible (wouldn't they be so close they destabilize each other's orbit?). That's awesome!

@argh523 7 лет назад

> wouldn't they be so close they destabilize each other's orbit? Normally, yes, but if their orbits are syncornized, it's a stable system. For example, three of Jupiters moons (Ganymed, Europa, Io) are in 1:2:4 resonance, so for every orbit of Ganymed, Europa orbits exactly 2 times, and Io exactly 4 times. That way (orbits with exact integer ratios), the gravitational attraction of the objects on each other balances out perfectly.

@solanofelicio 7 лет назад

argh523 Thank you! So, are all seven planets in TRAPPIST-1 in orbital resonance? It looks remarkable to me that so many can.

@axelkusanagi4139 7 лет назад

Truth is stranger than fiction, and we only really need Trappist E, F, and G, (or 4,5 and 6) to be stable. So long as the other orbits don't destabilize in a domino effect with those 3, Trappist could be the new seat of humanity. With three planet's resources to muster, and space elevators taking advantage of the periods where the planets align/proximate, we'd be on better footing than we started. And as a society with a history, we'd be better equipped to create a utopia. Just remember, if you get on a spaceship now, be prepared to meet people from the future.

@argh523 7 лет назад

According to /wiki/TRAPPIST-1#Orbital_near_resonance: 6 of them are in near-resonance, while for the outermost one it's unknown (this one is also quite a bit further away from it's nearest neighour than the others).

@polygondwanaland8390 6 лет назад

I think we should fully expect sentient Aliens to either have religions or to have had them at some point in the past. The emergence of Religions is something that probably arises naturally out of sentience + being a communal/social organism, and is also evolutionary advantageous, at least during certain parts of civilized development. I wouldn't expect it to be something unique to humans at all.

Intelligent design doesn't necessarily concern the unique qualities of Earth, as perceived by human observers. It concerns More so the fundamental nature of the universe as being a complex model of broken symmetry on all scales attempting to reach equilibrium (hence entropy). "Intelligent" is in the fact that symmetry is even a thing. Implies a sort of signature contained within everything, where philosophy suggests it doesn't "need to" for any reason.

@matthewpick4404 7 лет назад

How is it that we are able to detect planets in other solar systems so effectively using the dimming method? As in, how do so many star's planets move in front of their star from our viewpoint? I would think it'd be extremely rare to have just the right orbit. Is it due to all the stars in our galaxy being on the same plane?

@garethdean6382 7 лет назад

It is, difficult that is. The orbit doesn't have to be exactly side-on, as long as the planet passes in front of the star (The required angle range becomes larger the closer the planets are to said star. For red dwarfs any habitable planets are about guaranteed to be that close.) This does of course eliminate many systems (Which must rely on less useful methods such as the doppler shift of the central star, something best suited to finding close, massive planets, so called 'hot Jupiters' that dominate exoplanets to this day.) but there are so many, many stars that at least a few are expected to be right. However the rarity of this observation is part of why it's notable while the literally thousands of other exoplanets are not.

We aren't. I mean, when the planets actually get close to passing between us and the star we are effective at using it, but so many of them don't. The reason you hear about it a lot is because it's the best method we have when the prerequisites are met, but by no means is it useful for most solar systems because most don't meet that prereq.

@coopergates9680 6 лет назад

+Gareth Dean Isn't the doppler oscillation pretty reliable for red dwarfs due to their low mass? It would, however, be very complex for Trappist-1 thanks to combined effects from {seven} planets.

It was worth to wait for your presentation of the Trapist-1 system. I've seen same material on 4 other channels in recent days but this one was best and most detailed. Of course.

I think humans are too focused on the whole "life" thing on other planets. We imagine that if we find something on another planet that it will have some earth features that we can compare it too. What if there is something there that we can not even mentally comprehend. Space is big and scary place and we need to be aware that there could be something beyond our capabilities of understanding lying in wait.

@User-jr7vf 7 лет назад

Alan Phelan indeed there can be rather different forms of live, but yet we would not expect something that violates the well-known laws of nature

@alanphelan4270 7 лет назад

User Droid We know what we know about this planet and somewhat about our neighbouring planets. Our technologies are not so advanced that we can predict or determine what lies ahead in deep space. We can only take what we find and compare to what we know. Caution should be taken for the unknown. At the end of the day man has walked on the moon and thats the furthest physical humans have gone.

There's nothing wrong with going beyond our capacities, that's how we got to where we are today. You'll never improve if you're afraid to try something new. That being said, life is rather a bit overhyped, I blame science fiction and our own bias for living things.

@TheTacticianVXP 7 лет назад

(The question is at the end of the message) Firstly guys I love your channel. It is extremely informative and provides answers and updates to questions ans news of the latest astronomical research and facts. Although ejection rates and speeds of stellar winds vary with the mass of the star; the more massive and hot the star would be the more stronger its stellar winds would be and so more mass would be ejected. We saw that Trappist-1 Red Dwarf as both, its mass and temperature is less than than our Sun, but the small distance between the star and the orbiting planets would weaken the magnetosphere aided by Tidal Locking and the CME 's themselves would be dangerous. We were told thet the winds from Trappist-1 might have eroded the planet's atmosphere when the star was relatively active. So as one of the main key points of a Habitual planet, a atmosphere is removed, doea that mean our only hope of finding another habitual planet is Proxima Centauti? Is there still a chance that the Trappist-1 Solar System could have life in one of the planets?? Plz reply in your next video. Thanks a lot..

thanks for the detailed explanation of the newly discovered exoplanets. other channels barely mentioned their atmospheres or the fact that they're probably tidal locked. let alone how big other planets and the sun is in their sky.

thanks for including at least something about the magnetic influences in the TRAPPIST system. It is often lacking in other articles even though it is very important when considering if there is an atmosphere or plate tectonics.

@jellyboy123 7 лет назад

i got to say our planet is perfect. All the planets we ever see is never as perfect as ours and we should appreciate our planet and also live life.

@injunsun 4 года назад

Isaac Arthur has covered this some on his futurist channel. Mirrors and shades can be used to create day cycles, as well as filter the light into something closer to what we like. Both he, and Astrophysics Digester, Anton Petrov ("What Tha Math"), have mentioned the CMEs as likely being sterilising. Sadly, there's no easy fix for that.

@progman965 7 лет назад

@francoislacombe9071 7 лет назад

I read an article somewhere, I think it was Sky and Telescope, saying that atmospheric winds could exert enough force on a planet's surface to break tidal locking on such planets. That would improve climate conditions on planets we would otherwise think hostile because of expected tidal locking.

@liamgibson6949 7 лет назад

The thought of finding planets that could possibly be capable of supporting life outside of our own Earth is spine chilling. If there is life there, could they know about us? If we somehow figure out how to get there in a reasonable amout of time, what will we see there? Im so excited to see developments on this discovery. Also keep up the great videos! Best part of my week is watching these videos!
