Teresa Zhang exactly

mrseaweed1000 YAYYY!!!

Being a science geek is immeasurably sexy.

What is the answer to life super computer? *_42_*

But what is the question?

What is 6*9?

Sounds too mathematical.

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

Sadly that lather is more likely.

@@married222mayhem2 Yeah, but then they'll form the Trappist Union. But someone would always want to exit…😏

@@ScientistDog and then they'll be like "don't you guys think we've a common enemy 39lightyears away from here"

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

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! =)

" 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!

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

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.

And then a TV Series, sequel to 'Mission To Trappist 1' called 'Mission To Trappist 1b'

Where Matt Damon gets lost on it

he gets lost again? damn it, inject a tracker on him this time or a dog collar..!

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!" kzfaq.info/get/bejne/i86laLlpu7jcdok.html

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

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.

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.

A funny thing happened on the way to the moon

+Gillio I'd be dead by then lol

Are you uploading this story somewhere at the moment or is it still in the conceptual stages?

I wrote the story back in 1999 and turned it into a comic but my skills as an artist were not as good as I am now so I'm remaking it. Kinda like Avatar movie minus the unoptonium and civilized man saving the savages trope.

You mean the paradise volcanic planet?

Sounds really cool!

unfortunately more like solar radiation/volcano hell hole

Sammikins 8:20

Not as alone as a star sitting in the void between galaxies. :3

Sammikins I kept seeing that and it's gnawing at me now... is it because we'll be long dead, as a species, when the sun dies? Does it have some horrible lovecraftian meaning?

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..!

Tom Nally No, their beer is OUT OF THIS WORLD! Haha, bad pun.

ProgressivKSA either a long long long way from near-lightspeed, or next year. can't tell.

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

Michael Penny TRAPPIST-1 is a Dwarf star.

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.

Lutra Nereis Except for the massive radiation...

+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.

Study & Practice all you want to.! #AspiringAstroPhysicist

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.

sciencemanguy thanks a lot for that ! that was really helpful. all the best for your future career !

WooferJr same here XD

Note: I am actually in the same place you are. I'm also a 12th grader at H.H. Dow High. Lol. you thought I was a college student. Wow. We both are here trying to see where we can go for our future.

Cinq Cents 😇

GildedBear Earth-like-but-not-the-way-you're-thinking-about-without-water-well-maybe-water-why-are-you-asking-this-ish.

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

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.

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

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.

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...

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)

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.

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

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.

Benedek Nagy very true

good eyes bro. edhuku nu than therila

+Arun Kumar Seema comment! :p

Nice catch

axnyslie science = science fiction.

could happen tho

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.

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)

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.

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

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").

And even in Humans regular cycle lengths vary considerably.

lol what

Obviously you have identified a gap you could fill.

XD

Jealous?

"Pretty sure the lunar menstrual cycle is a myth,"- EE Ehrenberg

Damn it...

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.

Many signs of alien civilizations have been found so far and we’ve had contact with many aliens species, it’s just that the government prevents the media from broadcasting it to the masses

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.

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.

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

I noticed that too. But she was obviously just super excited to talk to her old prof.

Touche'

My life is complete now.

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.
