Nearby Star Has 7 Earth-Sized Worlds - Most In Habitable Zone

[Vastator]

Before you get too excited you may want to look at the distances from their parent star. And their orbital period. These planets are much, much closer to thier star than earth.

3 of the 7 planets are in the habitable zone and they are only 40 light years away. I don't think it will get much better than this

The same around a G-class star with planets rotating + large moons = better.

I think that often times, in the search for habitable bodies in space; the field of view is unnecessarily narrowed. I don't think moons are given enough consideration. Take Jupiter for example. So, so many moons. A few of which are candidates for being capable of life in some form or another. When people started looking out into space the majority of planets seen were gas giants, and were written off for not being rocky, and or in the Goldilocks zone. It seems that if we focus on only rocky planets in the Goldilocks zone, we're eliminating at least half of the potential worlds that can have, host, or sustain life.

Nearby Star Has 7 Earth-Sized Worlds - Most In Habitable Zone

It will be announced tomorrow by NASA that Michael Gillon et al have confirmed 4 more Earth-sized planets circling TRAPPIST-1 in addition to 3 already discovered.
It is possible that most of the planets confirmed thus circling far TRAPPIST-1 could be in the star's habitable zone. The inner 6 planets are probably rocky in composition and may be just the right temperature for liquid water to exist (between 0 - 100 degrees C) - if they have any water, that is. The outermost 7th planet still needs some more observations to nail down its orbit and composition.

Fucking awesome!!! Love science and love nasa!!!

Now all we need to do is have all of Earth's geniuses focus on creating much faster than light flight and the universe is open to exploration and habitation. No doubt there are billions of habitable planets in the entire universe, enough for each individual. Give us each a planet so we don't have to put up with the neighbor and his/her dog that craps in our yard, religious nut jobs coming to the door, politicians and criminals.

I would go to another planet with 100 other people. Doctors, scientists, construction and carpenters and engineers, fertile women ready to populate the planet.

It would be great if there were no animals that could harm us or we have weapons.

I would want to go with a liberal minded group. No Republicans. Our planets will be much better than conservative planets and no doubt red planets would make up the dark side.

sssshhhhh.....maybe the OP & others of his kind will move there.......

Your liberal utopia would be shattered the moment one person broke ranks, and got tired of the lazy amongst you benefiting from his hard work. I'd give it a week. And I'm being generous here...

40 light years is several generations of people away. You'd have to get a ship that not only would last for several centuries, but also be big enough to carry enough people so that there would be a population when they got there.

Nope.........sounds nice, but it's just a pipe dream right now.

And with such a quick orbital period they can't have much in the way of seasons.

The planets will still have seasons, just shorter ones because of the shorter year.

Quite possibly no rotation at all. Being that close could very well leave them tidally locked, giving you a searing hot day side, and a blistering cold dark side. Which would leave only a small ring at the boundary with potential for habitability.

 

[miketx]

^ did you see the orbital periods? They are measured in days. They can't possibly have any meaningful seasons like we have here. The first one orbits in less than two days. The last one in 20. So 5 days of winter, five of summer? etc? No way.

Yes, the hazy gloom of the terminator. It don't matter anyway. Unless they find some kind of fast way to get there, we'll never see it.

A generational ship sent in its direction able to sustain a population could do it over centuries at the rate rate of speed. Of course, my first generational ship would be sent to proxima b and maybe other closer ones.

Maybe with time leap frogging we might get 40 light years to land a colony...

 

[miketx]

What is the "rate of speed" you refer to?
