Exoplanet b has a Trump-like tint to it!
I wonder which one has the most oil(rocket fuel) so we can go to war with them! Earth! Earth! Earth!

I saw a news story about this last night. For me the coolest part is how they orbit so close to each other and he fact that you can see them from one planet.........its like having 4 moons.

I wonder if the fact that those planets orbit so close to each other will affect their gravitational pull or something along those lines.

I wonder if the fact that those planets orbit so close to each other will affect their gravitational pull or something along those lines. They are all closer to their sun than Mercury is to ours, the furthest one away is still 6½ times closer than Mercury, although their sun is much smaller Two of the habitable ones are just over half the mass of Earth, and the other about a 35% more mass (though with the current ± they could all actually be roughly the same mass). But even with that much mass difference compared to Earth, it looks like they all within 25% of the physical size. So less gravitational pull would be expected. What's also cool is all but one of the planets have a solar year of under 12 days. I wonder how that would affect seasons. And of course it could all be a moot point as just because they are in the habitual zone, doesn't mean they are habitable. Earth for example isn't the only planet in our own habitual zone, but we can't survive on the other ones that are.

This kind of stuff is so cool. What if's are the best part about space talk.

Three in the habital zone. Interesting. Beat me to it! Yeah, this was amazing news. I was pumped when I heard it. 39 light years is pretty damned close, if you're talking stellar neighbourhood. If you can get one of those mini solar sail probes to your nearest star (should be possible to launch in the next few decades), we should be able to make it to this system as well.

Double negative. So it's real? Doesn't look flat. Definitely fake.

Ha I think we'll be waiting awhile longer. Anyways yeah very close, and honestly launch date for one of those probes could be under a year. The tech is already there, it is just someone willing to devote the resources for it. The issue is it having an uninterrupted flight. Hell if it turns out the theory solar sails can be affected by tachyons under the right conditions, the probes could reach it while most of us are still alive.

I might not know what I am talking about but if it takes 40 years to get there at the speed of light then won't it take 40 years for the info get back to us once they are there?

If said info travels at the speed of light, then yes, yes it would. More likely would be sometime in the next few decades sending probes to do scans, samples, etc. I'm not sure it isn't safe to assume some life already exists on one or all of the habitable planets there.

Well part of it comes down to the the theory of using Tachyon to travel, in which case that is faster than the speed of light. In some theories it is possible to use tachyons almost like waves to allow a sail-based ship to go faster than light while still ironically not having the technology to send information faster than light.

The Voyager was launched in 77 and still hasn't left our solar system yet (seems like it did in 2013). It takes light 5 hours to get from the sun to Pluto and it took the Voyager nearly 40 years to go a shorter distance. A lightyear might as well be at the edge of our universe with out current technology and any travel near those distances is merely theoretical right now.
While it is very exciting to think about, we will be long dead before there is even a miniscule chance that we can make that journey if the human race isn't extinct before then. I would just like to see evidence of life elsewhere before I kick the bucket.
Edit: my numbers may be slightly off but you get the gist.

Yeah, just for comparison sake as to how far shit is: it takes light 8 minutes to reach earth from the sun. It takes light over 3 hours to reach Pluto. Even though most models always squish the planets together so that they look like they are equidistant, nothing could be further from the truth. The farther away you get from the sun, the farther apart the planets are.

I would just like to see evidence of life elsewhere before I kick the bucket. Edit: my numbers may be slightly off but you get the gist. You're right about Voyager, but we're a lot closer to being able to get something to another star system within our lifetime than we were then. Moore's Law has resulted in very powerful computing being available in exceedingly small form factors, and tiny devices are much easier to move at high speeds (less energy required). breakthroughinitiatives.org/Initiative/3If it's possible within a couple of decades to get one of these devices towards launched Alpha Centauri (~4.4 light years away; 20+ year travel time estimated), then we can expect to receive data back roughly 25 years after launch. So yeah, most of us will be pretty damned old by the time that happens, depending on how fast the technological breakthroughs required occur. That still makes getting to the TRAPPIST-1 system a generational waiting period. If we're talking the same speed as the theoretical Alpha Centauri project, then we're looking at just under 200 year travel time if we're lucky, with 40 years to wait for the first signal back after arrival. The real excitement with these newly discovered planets for our generation will start with the launch of the James Webb Telescope in October 2018.

Agree about Voyager not being an apt analogy. It's like saying a 40 yr old computer takes 10 min to boot-up. Dude . . . it's 40 yrs old. Have you seen the new iPhone? The shit a conglomerate of nations or SpaceX or whatever will put into the cosmos in 2035 to go chase one of these rocks will make the Voyager literally look like a Model T sputtering and popping along on wagon wheels as a Ferrari screams by doing 185 mph, disappearing into the distance before you can even get a look at the plates.

If you guys think we will get any thing more than a glimpse to that star system before you guys are dust or at least shitting into a diaper unabLe to remember what an exoplanet is, you are high or fucking retarded. Yes, it is an apt analogy because we are no closer to being able to travel 40 light years in any real human timeline than we were when Voyager was just a thought.

Yeah, the fastest spacecraft can go around 36,000 mph. Solar sails are projected to be able to go 150,000 mph. Woah, that is 5 times as fast but it doesn't matter when you are needing to travel 2.351e+14 miles. It takes light 40 years but we are totes gonna get there in our lifetime with that Ferrari spacecraft. Pfft. It would only take around 180,000 years with our best technology now. Even figuring we can find something that goes 10 times as fast would still make us all dust before the spacecraft gets there.

It is so hard to fathom a trip of 180,000 years traveling at 35,000 mph is our closest real neighbor. The fucking universe is pretty big!
