Findings in title quoted from the linked summary^1 for a hyperlinked journal paper.^2

From the linked summary^1 released by the Max Planck Institute for Astronomy:

>A team of astronomers led by MPIA scientist Diana Kossakowski have discovered an Earth-mass exoplanet orbiting in the habitable zone of the red dwarf star Wolf 1069.

>Although the rotation of this planet, named Wolf 1069 b, is probably tidally locked to its path around the parent star, the team is optimistic it may provide durable habitable conditions across a wide area of its dayside.

>The absence of any apparent stellar activity or intense UV radiation increases the chances that Wolf 1069 b could have retained much of its atmosphere.

>With a distance of 31 light-years, Wolf 1069 b is the sixth closest Earth-mass planet in the habitable zone of its host star.

>Because of its favourable prospects regarding habitability, it is among a small illustrious group of targets, such as Proxima Centauri b and TRAPPIST-1 e, to search for biosignatures.

Probably a good way to get attention for your paper but tidally locked, red dwarf and a 16 day day orbit are probably not ideal.

You know where else is habitable? Earth. Maybe we should worry about the one planet we do have

We do worry about the one planet we do have. Well, at least the scientists do. That doesn't stop us from exploring. Ofc people with small brains can't comprehend the idea that science isn't mutually exclusive and that we can do multiple things at once. Progress isn't linear and does not require we all focus on one thing.

Screw earth mass though. Let’s pick a planet with less gravity so we can have more fun.

We'll develop a probe at half the speed of light, so it should reach the planet in roughly 60 years

50 years later

Ah christ I think the probe hit a random asteroid in deep space

It would be nice if we used different words for habitable for humans, and habitable for some kind of life in general.

But then no one would click. I guess that could be the title for the chapter in the 22nd century history book about this era.

More health issues than we can quantify, that's why a huge part of manned spaceflight has been relentlessly studying the effects of reduced G's on the human body. To say the least, EVERYTHING starts to go south after just months in a reduced g environment, we don't know how bad it will get or how lethal it can be upwards of several years

Generational projects, and methods of keeping socio political issues from derailing it all. That will be hard with a species so focused on immediate profits. Generation projects of this magnitude don't pay off quick, I don't know many rich folk interested in doing things that won benefit them before they kick the can

No, but its day is essentially the same as its year, so the sun wouldn't appear to move in the sky, and the planet has a day side and a night side and the lack of light changing would be a tiny irritation. But if you colonized it you'd sleep indoors anyway and artificial lighting would provide a normal sleep cycle.

My guy, it won't be aristocracy. It's gonna be rampant space imperialism, you know, like we do every single time we find resources in mass ripe for the taking. Hording resources, and controlling planets in the solar system is gonna end up being their goal. They will have no interest in a project that won't make profit for 200-500 years. This ain't months without profit, this is lifetimes of investment with no gaurentee of a return (because we don't have a clue how possible this really is) the conquest of the solar system is far more likely (and we've already started it) than an interstellar one in the near to distant future. And money is already being made in it

Well, interstellar probe travel should be possible before then, but humans are leaving the solar system anytime soon without some revolution in tech.

One day we will make it, probably in massive several km long O’Neil cylinders powered by nuclear drives able to scavenge interstellar gasses.

First though we should be looking get a dyson ring round the sun to solve power needs

I have always wondered about planets that rotate slower or faster and if that would affect things like sleeping and aging etc. I suppose your body gets tired after x hours of waking so yes artificial lighting and black-out curtains could help, but in place very far north, it's well known that we simply don't do well in limited day or night environments. Still would be interesting to see if we ever get to be interplanary!

Who is ‘we’?

Do you mean that the majority of users in r/science may not read linked content, or excerpts in comments?

Do you also mean that such users need in-title explanations for scientific words?

But then 30 years later we will have a Probe that goes twice as fast as that one and then we design a Probe that is double the speed of that one and they will get a cool Probe first and each Probe after will get worse with less information that's outdated.

The real problem here is that so many of the uninformed don't realize that there are hundreds or thousands of scientists that specialize in each individual section of science.

There are maybe 10 popular climate scientists that make headlines, but maybe 1 that might make headlines for some hopeful half-invented article.

But there are definitely hundreds of scientists that spend their entire career (30y270d8h= 65000 hours) each focusing entirely on each of these sciences.

Venus is right next door, and if you don't mind not living on the ground it's pretty habitable given our current technology. You can make graphene from co2, and then you could use that graphene to build more habitat. The sulfuric acid also isn't as much as a problem as people make it out to be. Sulfuric acid H2So4 which is just 2 waters bonded by a sulfur atom. If you have sufficient electricity sulfuric acid can be turned into water. It even has phosphorus which is essential for all life.

If you want to surf the skies Venus would be the target.

Red dwarfs are redder than our sun, but they aren't really a color anyone would describe as red. Their surface temperatures are around the same as the filament of an incandescent lightbulb or hotter, which means it would be about the same color as an old fashioned light bulb.

Humans have had an insatiable urge to explore, chart, and colonize every square inch of habitable land for as long as we've been humans.

The morass of space will not stop us. We will spread and claim and consume until we have conquered every last bit of empty of space in the galaxy. Even if it takes us a million years.

Honestly it isn't even about our long term survival.

Humans want to explore and expand and grow. They think there's a place they can go to set up shop they're gonna go whether it's a good idea or not.

They are sending a few missions to Venus. One of them even utilizes a balloon to stay in the upper atmosphere for an extended period. I would rather see crewed missions to Venus then Mars. Mars has dozens of ways to kill you while the environment in the clouds of Venus is comparatively simple. The only thing that would give me real pause is if we discovered life on Venus.
