E, F, G are in the habitable zone.

E and F look pretty earthlike if those pics are anything to go by

F seems like it's the best bet for a replacement Earth with it being water rich while E is more temperature-like to Earth. Nine day transit tho is insane.

Three earth size planets discovered in the goldilocks zone around the same star - the Trappist 1 system.

The planets are also accordingly relatively close to each other so you would see the others in the night sky, clearly.

The JWST NEEDS to make it to space safely. Goodness, can you imagine if they detect synthetic gasses in the air? We might get evidence of aliens before I die after all, or at least proof that it's possible.

And why would I want them?
sure would be cool if someone could figure out a way to travel there without it taking a thousand years. cmon humans!! surely someone on this planet can figure out how to fold space and unlock interstellar travel!
 
Can you imagine how crazy it would be to live in a solar system with multiple planets with intelligent life? Early telescopes would look at other planets and see civilisations.
 
Is the star much smaller than ours? How can they be so close and not roast?

Trappist-1, however, is nothing like the sun. It's what's known as a red dwarf, a very small, comparatively cool star, barely 11% of the radius of our sun and less than half its 10,000º F (5,500º C) surface temperature. Historically, astronomers ignored red dwarfs in their search for habitable planets. If the only star you know of that has given rise to life is a larger, yellow, so-called M class sun like ours, why look at ones that are so much smaller and cooler? But if you huddle up close to an M dwarf you can soak up all the light and warmth you need. What's more, there are at least three time more red dwarfs in the galaxy than all other classes of stars combined.

Considering the close proximity of the planets, shouldn't there be a bit of a tug and pull on them to make them tectonic and possibly highly volcanic?
