"time to eat another retribution salad". I have no sufficient words. Your closing quips are amazing.
Indeed , i prefer an exoplanet with seasons rather than an exoplanet tidally locked , hopefully the ESPRESSO spectrograph helps to confirm the existance of Tau Ceti e
Retribution Salad: I am putting that on my menu.
"Hey Bob, what season is it on that exoplanet your looking at?"
Bob- "Same one as the last time it transited"
"damn it!"
Upcycle Electronics I was wondering about that as well
What reference is this?
During transit the planet reflects very little.
I only just discovered your channel yesterday and am now binge watching all (or rather binge listening) your videos while I play No Man's Sky.
Keep up the good work and hails from Australia!
I enjoy your closing comments so much! I mean, the content is great, but the endings are a very nice cherry on top.
"The hubris of the plants knows no bounds"
Thank you. I thought I was the only one who thought this.
Perfect timing for a relaxing pre-sleep video. You’re the man, JMG. Keep up the great work!!
Zachary Fluke I thought I was the only one who fell asleep to JMG’s videos. Super chill. Problem is, when I wake up I have to backtrack and rewatch the ones that played when I was asleep.
Lol I do it too. He has the perfect voice for it but still, like you I have to go back the next day to re-watch it lol.
I never considered how arrogant plants are, but you're right
I love that you post the papers and everything!!
thoroughly love hearing from you keep it up!
I did research as a graduate student 30 years ago where we analyzed the screams of pea plants we cut in half. Now I don't feel so guilty for killing all those pea plants.
One issue I see is that we cannot now or likely in the near future we get data on exoplanet atmospheres on a smaller scale than a whole planet. If their seasons are anything like earth's, that means that the effect will be much diminished because we don't compare summer to winter, but the average of summer and winter to the average of spring and autumn.
I am getting excited, we are getting close guys! I give it 10 years tops before we find alien life!
great channel john. many thanks!!
Thanks for the continued education in the sciences and astronomy. Your videos keep imaginations alive.
Aw yeah, new video!
Great video! Keep up the good work!
Thanks, for another thought-provoking release, John,... We'll find something within the next 10 - 20 Years, this I predict, lol. Until next time, John, leave them Plants alone.
If we only get to study the composition of exo-atmospheres when an exoplanet is passing between us and its star,
it could be really impossible to study them at different exo-seasons, since we only ever see them at the same point in their year.
Excellent material .This is my kind of channel with a mix of what I'm interested in and done so in a rational scientific way but not the rigid dogmatic scientific manner I've seen before on other channels . I saw a recommendation for this channel by someone who was visiting Secure Team 10 .The commentor said she recommended this channel of yours . Glad I checked into the suggestion ! 👍
I had thought that the James Webb telescope was supposed to be launched this year ? What gives ? Now it's scheduled for May 2020 ? Of course I'd rather they get any and all bugs worked out before launching considering the fact that it costs 10 billion dollars and we won't exactly be able to make a repair mission possible for quite some time in the future if ever considering the fact that we spend way less on space exploration than our national defense . I just want to see what it discovers and I'm anxious to see it launched ,but better safe than sorry I guess. I know that even after it gets launched we'll still have to wait for quite awhile while it gets into position and goes through all the diagnostic tests and unfurls its equipment . That's going to be a stressful time for the whole team for sure .Anyway I subbed and look forward to seeing more of the videos you have.
Welcome aboard! Yeah, the JWST delays are maddening, we've all been waiting for that telescope for years. I'll just be glad when it's in orbit, and functioning. Until then, I'm figuratively holding my breath.
Your next book should be called "The Hubris of the Plants"
I'm going to eat a steak, because the cow was a vegetarian for me. Maybe I'll ha e a side of retribution salad.
Pax Aboll, Are you sure about that? If you are not seeing a "certified free range grass fed" label it likely was not vegetarian.
@John Michael Godier -- Can you make a longer video speculating (educated guesses, real possibilities, any thoughts) on the reasons for the possibly even accelerating expansion of the Universe? Possible involvement of Dark energy, a new Universe growing somewhere in our Universe? Collisions with an "adjacent" universe etc.
I don't understand science but I love your channel my dude.
Just F-ING Awesome!!!
Love love LOVE your channel but dang! Your last few videos have been sooo short
You're in for a surprise! Longer videos are coming .... soon.
Haven't checked out the paper but it would seem like the planet would need to have an asymmetry between the land masses in the northern and southern hemispheres (like Earth has) in order to detect seasonal variation in the overall photosynthetic output of the planet.
Should have said "amazing universe in which we live unfortunately alongside arrogant plants"
My only complaint is the vid is too short
Edit:still smashed that lile button
You know this makes me think. Science fiction always assumes no matter how weird the creatures on an alien planet get that we will see relatively normal plant life. At most it can be different colors, maybe has weird looking leaves, flowers, or something like that but we assume the flora of a planet to look and function much like earth plants. This is probably because it is harder to imagine an ecosystem with a radically different base then it is to make small changes to the top end of the food chain. But it makes me think, what other forms could xenoflora take? hmmm...
MegaAwesomeNick - it's all fungi out there...

Iirc there was also a Space 1999 Episode, were all plant life turned out to be extremely deadly. Oh and they had an episode about a murderous, intelligent plant too.
The problem is, we may have already seen biosignatures in the atmospheric chemistry of Mars and Venus. Those signals are ambiguous. I suspect we will find several ambiguous signals from exoplanets when we have the technology to see them. The question is, will we ever see any unambiguous signals?
Thanks John, sometimes I need the reality check before bed.
Any second grader with a crayon can tell you that intelligent alien life is all bipedal, mammalian, and speaks English. Most Planetary anthropologists, up until June of 1997, agreed with them and wrote thousands of books that were bought that were read by millions of people. It was a good system of belief that kept everyone happy and feeling safe. Now people like you come along and start changing things and making people uneasy. Turn your attention to something worthwhile, like weapons development, and stop upsetting people. Belief is more important than truth.
Love your videos John, you got a new sub in me bro
Doesn't an exoplanet alway transit, relative to us, at the same exact time of its year?
We will always see the same season.
But what if it is evil plant life bent on universal domination....I am just saying.......anyway i always enjoy your posts.
We could send in a squad of zombies to deal with the plants.
Let's ask Gil Levin how excited NASA is to use its resources to investigate non-terrestrial biosignatures. Now, sniffing rocks? Billions!
What is your opinion on the declaration this week that octopi are an alien species that came to Earth in frozen biopods?
Yay plants!
Eco Planets...bearing fruit...
Awesome.
Plants are clueless but they are considered to be a life form.
Just like my neighbors
"Retribution salad" lol
Woot!
Maybe plants know more than you might think!
I would like to smoke a blunt with you. Man, your show is a trip!!
Can't wait to see what the next generation of telescopes show us :)
Nude aliens that are making very, very angry gestures at us.
Totally ungrateful trees.
SUPERCOMPUTER LIQUID MIND WITH AI CAN BE ACHIEVED WITH ARTIFICIAL NEURONS
A quick one this time.
Honestly they expect that kind of resolution from our instruments? Seems far-fetched.
Maddog, Its far fetched for the instruments we currently have, but not far fetched for the instruments we are capable of building.
Except there might be no season on an exoplanet with plants... :(
Where is the James Webb telescope when you need it. It should have launched in 2014, now what is the delay, more money?
The James Webb telescope failed some safety tests a year ago indicating that it would break if it deployed. So they need more time to make it work right. I share your frustration, but it's better to be late and do it right than to rush things and have the whole thing fail.
Stretching the boundries of science and engineering sometimes results in delays and overruns. I hope they triple check everything. I want that beautiful machine to work for years.
Its NASA what do you expect lol? Probably won't be launched till 2030 lol.
PhotoGeorge
It wouldn't repeat. The location of JWS is far beyond the point where we could reach it for repair. So problems would be permanent.

I smoke analogues a plant life
FREON FROM DEODORANT
Yeet
Naw. There'd be yet another reason that it wasn't life and would need yet another detectable signature, then maybe another. lol
⛅Hi Sunshine, even tho the World has been plagued with despair an in Human suffering, I am still an optimistic person that believes that finding the Lifeforce energy on other Planet's will be as easily done as it will be to create it on other. May peace an prosperity be with you always. C-ya😎Bye!
"✌💖🤗~🌞🌎⚬" ...
… and then the millennials discover that those exo-plants can be smoked, and the world learns of another great filter…
