Red dwarfs are known to be cooler (the habitable zone is therefore closer) and unstable.

I don't think LHS 1140b is "Earth-like" at all. Rather, it's more like a mini-Neptune, being boiled off by its star.

Edit: JWST emission spectroscopy of LHS 1140b as it passes behind its star rules out a mini-Neptune. https://arxiv.org/abs/2406.15136

Close enough that we could probably develop a probe to get there in the next few centuries and check it out. What are the current popular candidates for propulsion systems capable of accelerating to near the speed of light?

Yeah, but not that much.

Well, if they observed not only a planet orbiting the star but also the planet's atmosphere, it must not be a very "distant" star.

I know I'm a killjoy, but I do think there's something negative about the impact of science fiction on engineers. Like, the people who tend (no offense) to be the most literal, black and white thinkers get exposed to art and instead of processing it as the output of human creativity, they start to imagine that it's desirable or even real.

Life is already on this planet. Why would it matter whether life exists outside of this planet or not? I mean, this is pointless. I understand that some have a financial motife to drive this narrative, but it is not logical. The counter argument is quite simple: IF there is no divine being, then ALL of life's complexity is logical and natural. So, it really does not matter WHERE it originates nor how many times. Why would it matter if it originated 10000x or only once? Now, I do not doubt that it has originated several times rather than once, but my point is that this extra-terrestrial search MAKES ABSOLUTELY NO SENSE AT ALL. That is not to say that research and exploration in space are pointless, but that it IS pointless to "search" for extraterrestrial life. Yet none in the media point that out. It's all as if it were some magical, mythical quest here.

NASA has a neat exoplanet catalog where you can also switch to its solar system view

Super-Earths are interesting but not technically habitable, at least not by humanoids, the gravity would be insane

There are new telescopes and techniques coming online really soon that can potentially find closer to Earth-sized planets but they probably won't be within 50 light years

adding: hmm maybe gravity not too horrible on 1140b but still INTENSE

(assuming Google's "AI" is correct)

> Gravity Formula: \frac{Mass}{Radius^2}\)Calculation: \(5.6 \div (1.73)^2 = 5.6 \div 2.9929 \approx 1.87\)

> if you weigh 150 lbs on Earth, you would weigh roughly 280.5 lbs on 1140b

Nonsense. You mean not able to support terrestrial life.
