YASSSS! I'm so happy you're doing a video on this because me and my friend are doing research on this and keep in mind that were in 5th grade! we're both so interested in this! I just told her about this video. love you Dianna! Oh and we learned that the solar system is moving closer to ours! last time I checked, it said that the new solar system is 40 light years away, but now 39! Fascinating!

[@Tomyb15]

PrincessParkour I don't think it's moving at a rate of 1 lightyear per month. Not only does it break physics but it would also be our doom. The reason is probably that someone rounded up the number to 40 ly

[@danilooliveira6580]

they probably just missed the distance and corrected later. 1 light year is a LOOONG distance, even if the solar system is moving really fast. also love to see 5th graders so interested in space exploration, GO SCIENCE! =)

[@siRrk1337]

" it said that the new solar system is 40 light years away, but now 39! " so, a lightyear is the distance light travels in a year, and nothing can move faster, so even when moving at maximum velocity directly in our direction it would take the system a year, and its certainly WAY slower, so, maybe the info just got updated ;) dont wait for it to arrive here any time soon! btw, the speed it travels towards or away from us can be measured by "redshift". you should google "doppler's effect"; it has to do with the lightwaves stretching or squeezing when emitted from a moving object, thus altering the wave length, wich we percieve as a shift in color (thus "redshift"). its very interesting stuff. maybe u can find out if its realy moving towards us!

[@danilooliveira6580]

but they you will need to look at what are "lightwaves" and then what a "waveleght" is for light... and that is how you get locked in a wikipedia spiral of death and have a lot of fun while wasting hours of your day looking related things to understand just one thing

[@Eddygeek18]

Okay so say you last checked a week ago that would mean that the solar system is moving at 52 times the speed of light towards us (if that was even possible). It would be on top of us in less than a year. They just rounded the number up 40 is easier to understand than 39 so they said 40.

[@alasanof]

It'd be fascinating if each of Trappist's planets evolved intelligent life and they had interplanetary trade between them.

That's an option, the other one is war...

You're all wrong. It's gonna be a Star Trek movie and Capt. Kirk is going to drop a villain off at Trappist 5. 20 years later, he's going to be manipulated into coming back, only to be confronted with the villain yelling "This is -Ceti Alpha- Trappist 5!" kzbin.info/www/bejne/i5nYZolui7erfLc

[@GilFAMCPT]

If you think about it, we went from inventing airplanes to landing on the moon in less than 100 years, so who knows, maybe we'll be able to visit these planets sooner than we think

[@Unbelishitable]

Would you say that probability that humanity will send spaceship to another star in the next 100 years is over 0.9 ?

[@Sam-oz8pn]

No. That's my guess. Our current space travel advancements are extremely low. It's going to take Elon Musk, I repeat, the great overlord Elon Musk, at least 10 years to get his Mars thing going. Even if we master colonization quickly and space interest picks up, it's going to be at least 30-40 years. That's the optimal scenario. But who knows... understanding of relativity and quantum mechanics is increasing, and an unexpected breakthrough could turn the tables.

[@theelectricwalrus]

Gillio Well, when flight was invented, we didn't know of any reason why people could not go to the moon soon. Now, we do know of reasons why we can't at least send a significant probe to this planet: it would take way more delta-v than we can use.

[@raja777m]

first, the gravitational power of the sun will be reduced/decreased/losing slowly; then the planets comes closer to it or hit each other or fly away, far from the Sun, or just explode; then, Sun is alone, and it'll die alone..!

Universe has untold unimaginable places to experience and this planetary system is one of them.

[@spoonmp1]

Is Trappist-1 a much smaller star in order to allow planets much closer to it than our planet is to the Sun to still be viable to contain liquid water and life? Or am I missing something fundamental here?

[@pedroheck3667]

Michael Penny Trappist-1 is indeed a very small star, almost the size of Jupiter

[@krupap.357]

Michael Penny TRAPPIST-1 is a Dwarf star.

[@enhydralutra]

TRAPPIST-1 is around 1/10 the size of our star. Which is great news for these planets because not only are they not going to get cooked being so close to their star, but TAPPIST-1 will shine for 5 trillion years, meaning they'll be there long after our planet is gone.

[@Tomyb15]

Lutra Nereis Except for the massive radiation...

[@enhydralutra]

+Ciroluiro So they're bathed in ionizing radiation; no big deal. It's nothing a good magnetic field couldn't handle, and if none of the planets have one, it would still make a great site for potential colonization. We'll just have to bring along our own magnetic field.

I always wanted to be an astrophysicist since my 7th grade... and now I am about to pass my 12th grade ! any tips?

[@KyleCPM]

Study & Practice all you want to.! #AspiringAstroPhysicist

[@sciencemanguy]

I would highly recommend against becoming an astrophysicist. Unless if you are at the top of your field, it is highly unlikely that you will get a job in that field. Are you as smart as Neil Degrasse Tyson was as a high school senior? Yes, you have to be that smart to land a good job in that field. Think about it, our economy is based upon what the consumer wants. There is no "material" demand for exoplanets (I do understand the importance... I'm just showing what the rest of the world thinks), and as demand decreases, the jobs necessary also decreases. Here are some alternatives that still require an in-depth understanding of astrophysics and its components. 1. Aerospace/Aeronautical/Astronautical engineer 2. Satellite engineer (how do you think the Hubble telescope was made?) 3. Rocket analyst 4. Astrobiologist 5. Computer scientist/engineer (who do you think codes and builds computers on the ISS or SpaceX's falcon rockets? Who programs Hubble? Who programs all these mechanized systems?) 6. Programmer (read above) 7. Chemical engineer/scientist (how do you think rocket fuel is made? Also, remember how in the video how they discover the atmosphere of exoplanets? Yeah... chemists and chemical engineers contribute a whole lot to that) 8. Mechanical engineers (who do you think made the Curiosity robot?) Hope this opens your mind a bit to viable careers that still deal a whole lot with space travel. The best thing about these careers are is that if you get rejected from the astrophysical jobs, you can still function in our capitalistic society. When I was a teenager, I wanted to be a theoretical physicist like Hawking... until I saw how many jobs there are. Now I am pursuing an astronautical degree so I might be able to work at SpaceX or NASA.

[@GraveUypo]

i'm note sure i agree. they spent the whole interview dumbing down everything rather than focusing on the subject. i felt almost insulted by how oversimplified things were and the stupid analogies they felt they needed to use. in short, i like her practical science / experiment videos better. space time does this type of video hundreds of times better.

Fantastic stuff, I'm eagerly awaiting more data on this fascinating system. Thanks for doing this Dianne!

[@kevindahl-skog7992]

Is the lack of a bigger planet, like Jupiter in our solar system, a disadvantage for the evolution of life in that system? I guess that if you don't have enough protection from meteors and you could get catastrophic bombardment from the sky very often which wouldn't allow poor aliens to survive... :(

[@josephdillard9907]

Kevin Dahl-Skog you're right of course, the presence of Jupiter in our solar system played a huge part in the evolution of life on earth, but Trappist apparently lacking such a body doesn't necessarily mean life couldn't evolve there, I'm holding out hope that some form of life is there right now, even if it's simple (and of course it most likely would be)

[@Tomyb15]

Kevin Dahl-Skog Jupiter may act as an umbtella as well as a meteor-catapult. The fact that it's massive doen't mean that it will always deflect asteroids and bodies alike away from Earth, it may do the opposite. Bit even still, life on Earth either evolved quickly after the late heavy bombardment or it evolved before and survived it. After that I think that the number of asteroids went down dramatically.

[@joeybf]

Also I believe the meteors wouldn't be as common or violent, because of the tiny mass of the system itself

[@benedeknagy1]

I believe it's the opposite. The gas giants together sometimes modifies some asteroid's orbit, but the bombardment of a planet is necessary to shuffle the cards of evolution. Killing most of the life on earth did a good job at making a perfect harmonic biosphere. In the first few million years it might have helped also in gathering all the different elements from asteroids to Earth, making life possible.

[@josephdillard9907]

Benedek Nagy very true

[@Pirsqed]

Great job with this video! The interviews and editing really did it for me. Keep it up!

[@Juniper-111]

JWST When does that launch? Next year...

[@marcomcarneiro]

Fantastic interview, Prof Burgasser has shown great familiarity with the camera. Kudos for the video and the interviews.

[@scotttoborg4906]

If we find exoplanets by measuring the light differences of a star when a planet is in transit across its face, how do we know if all star systems don't have planets since, with most, we would not have an edge-on view of the system and thus no transit to measure? I know we can detect planets by measuring the wobble of the star, but would a wobble from a small, Earth-sized rocky planet be sufficient enough for detection from afar?

[@thekaxmax]

Scott Toborg that's been taken into account with the estimates of the probability of planetary systems. there's a /lot/, but not 100%.

[@Sam-oz8pn]

You're right, transits only detect perfectly oriented planets. We have other methods of detecting planets though. Yes, it is possible to measure the wobble of the brightness of the star. I think it's even possible to detect the varying degrees of redshift. Machines today are incredibly sensitive.

[@ireallyreallyhategoogle]

Doesn't everything in our galaxy tend to move on pretty much the same plane?

[@lakshaymd]

Ireallyreally Hategoogle That's just the rotation around the centre of the galaxy. The stars and nebulae can have their rotation around individual axes. This is because during the formation of the galaxies the motion of particles out of the plane mostly dies out but not completely. Since the planetary systems are formed from these nebulae, they can have any axis of rotation and thus any plane of rotation.

[@michaelderflinger5002]

About the first question- I asked this Professor Manuel Guedel since he showed a new photography of a protoplanetary disc viewed from the poles. He told the audience that we can only observe a tiny amount of planets with transits. But statistics tell us that nearly every star should have planets...

[@LegioRulez]

I have always loved Astronomy, ever since I was a little kid. I remember being able to draw our solar system back in kindergarten while other kids drew houses, cars and similar stuff. Read so much about it, learned so many new things... and I feel like a little kid again with all the new discoveries being made right now. So cool!! Also is that a solar system necklace? If it is, you just reached a new level of awesomeness!

[@fattie6180]

[@GoldenLion137]

Thank you for this. received more information in this 12 minutes than the mainstream papers ever could give.

[@217nomiga]

I'm confused. What does tidally locked mean?

[@enhydralutra]

It means that the same side of the celestial body in question is always facing the point around which it orbits. Our moon is tidally locked with Earth, which is why we always see the same side of it at night. Likewise, the same side of these planets likely face the star as they orbit, meaning one side is perpetually dark while the other is perpetually bathed in light.

[@kakadita]

michael_mu It means that the translation period of the object is almost the same as its rotation period, so the side that is facing trappist will always be the same! This also happens to the moon (that's why there is a "dark side" of the moon)

[@Master_Therion]

It means one side of an orbiting body always faces the star/planet it is orbiting. Our moon is tidally locked to the Earth, so we only see one side of it. These planets are (probably) tidally locked to TRAPPIST-1 so they will have a day side and a night side.

[@jacobrose2496]

michael_mu one side constantly facing the star(eternal day, possibly hot), the other constantly turned away(eternal night, definitely cold) and a ring of twilight/dawn in between

[@evandroa4845]

michael_mu It means that the time the small body (planet) takes to spin around its own axis is the same it takes to rotate around the big body (star). That means that only one side of the small body can "see" the big body. In other words, an alien living on one side of the planet would Always see the star in the exact same spot in the sky (always day) while another alien living on the other side of the planet would never see the star (always night). For example, the Moon is tidally locked to the Earth. One side of the moon always faces the Earth and the other never does (and therefore we wrongly call it the "dark side of the moon").

I am very surprised that you thought life was only on our planet. You must know there are billions of galaxies and 10^21 stars and you think only one has life? When hydrogen, helium, carbon, oxygen are common in the universe and make life here on earth. 😱

[@PhilipShepster]

Hilmar Zonneveld - You are aware that the distance to the nearest star at light speed is 4 years and it only takes 8 minutes to get from the sun to here. Its fast but very, very long distances. Also with governments turning on their populations all over the world currently, and the climate change, I don't think high level societies last very long before they go extinct as we are currently within the 6th mass extinction in the last 600 million years.

[@Sam-oz8pn]

A solar system (lowercase s) is a system around a star. (Solar being star). So really, any star with planets orbiting it is a solar system, just not *the* solar system.

[@coopergates9680]

Solar is for our sun, otherwise it's 'stellar' such as stellar activity, stellar flares, stellar composition, etc. Just as perihelion and aphelion are specific to the sun because of the "helio" in them, and moon around Earth -> Perigee and apogee. I think for other systems it's something like periapsis and apoapsis.

[@coopergates9680]

Otherwise, a "solar day" could vary wildly instead of being 24 Earth hours.

Hi Dianna. As someone else has pointed out already, the name trappist refers to a religious order. Monks from that order are famous for their beer (and very often for their cheese too). In common language, trappist is therefore not a particular beer but rather a specific kind of beer, brewed by trappist monks. Most of these beers are spicy, strong, and very tasty! Best wishes from Belgium!

There is a computer game called "elite dangerous", it uses a procedural generated galaxy to simulate our own. When This discovery was announced the developers looked at their map with the intention of updating it, what they found was a system, in almost the correct location, with a similar configuration, only minor tweaks were needed to put the full Trappist system in game. Yes it is possible to visit it too.

It's funny to see how incredibly smart Dianna is and how much she still doesn't know and how many things still genuinely surprise her. lol it makes me feel a little less stupid!

"Trappist-1 B o'clock" Oh! I love it!

[@KevinSmith-lo3bt]

I know I mentioned on your last video about planets etc but I didn't expect the answer quite so fast brilliant and informative

[@CaptainObvious0000]

the most awesome thing about it is how spectroscopy allows us to deduce all of that.

I was just watching Star Talk All Access, and David Kipping ( Assistant Professor of Astronomy at Columbia University) mentioned your channel...! So here I am, finally being enlightened by a physics FEMALE...! BRING IT ON !!!

[@Ballacha]

it's scary to think that our Jupiter is kinda like a star that failed to gain enough mass to ignite :O although it would definitely be super cool to live in a binary star system :D

[@dlegault20]

Glad you discussed the planets possibly being tidally locked. It something I wanted know about. Since you either have daylight all the time or dark all the time.

[@jacktribble5253]

I love all things physics, so your channel is an automatic fit.

I find this video super interesting. I love learning about exoplanets. I can't wait to graduate from my degree and go into further studies in astro-chemistry.

[@kranthikumarbagathi6738]

I felt the same amount of curiosity as you have when you are explaining it ...really excited to know how they measure all those facts about other planets at such a huge distances just by collecting a very little amount of light ...and even the atmospheric compositions ohh my god ....how do they find it ...how do they differentiate the light from the star and the light which is scattered by the planetary atmosphere ...really astrophysicists are incredible...salute to them ...and thank you mam ...your explanation and your zeal towards physics is so lovely ..

[@desiguy55]

for the past 2 years i dreamed up a sci fi novel based on an a small infrared star system like this. now this system really showed up.

[@eugenesokol3918]

This is the stuff I crave to know! Physics is the BEST of all the sciences. I just hope that some day we'll find a solar system close enough to get to.

[@billhaigney5080]

BTW: I was Happy to watch your videos with Simone and Happier to see you two being friends! The world is Better with friends!

[@jimcorbeil]

The day will come when I have something witty, maybe even interesting to share. Until then, you're stuck with my little smiley face. Keep up the great work. : )

I'm super excited for the JST to finish calibrating.
