Could a recently discovered "super-Earth" have the potential temperature and conditions to sustain life?
The new exoplanet is situated "fairly close to us" -- only 137 light-years away -- and orbits within a "habitable zone," according to NASA.
Astronomers say the planet, dubbed TOI-715 b, is about one and a half times the width of Earth and orbits a small, reddish star. The same system also might harbor a second, Earth-sized planet, which, if confirmed, "would become the smallest habitable-zone planet discovered by TESS [the Transiting Exoplanet Survey Satellite] so far," NASA said in a Jan. 31 press release.

“Only.”
Just give us 10 trillion dollars and 500 years and we can do it!
When Elon invents warp drive, put all the Marxists and Muzzies on spaceships to the nearest Class M planet.
We can’t go to the Moon...
It’s Krypton!
So all we need to do is figure out FTL travel and increase human life span by about 4-5x and it’ll be the perfect vacation destination.
Wow! That’s right around the corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner, corner,.
How much would I weigh on this planet like 2000 pounds?
The Orville TV show had a good episode dealing with this gravity problem
With a typical NASA rocket it would take substantially more than a million years to get there so best not to plan a vacation there anytime soon.
Here they come. Biden probably already has his people drafting the forms for automatic amnesty and an expedited path to citizenship.
The habitable zone of a small reddish star is fairly close to the star, which is bad news for planets in that habitable zone. Guessing by habitable they mean liquid water and life as we know it.
Small red stars like this type M (the most common type of star in our galaxy) tend to be much more active with flares, and the planet being very near the star, well within the orbit of Mercury in our solar system by comparison, leads many to believe planets this close may not be able to hold an atmosphere of significance.
A place we will never get to.
Hopefully, humans can flee the planet before some natural or human calamity puts us on the extinct list. I would assume we’d see some strange looking “humans” after 25,000 years of evolution on that planet.
If this is your field of study then 137 light years is indeed close in astronomical terms yet it is so far away that our species may never ever visit it.
The nearest real galaxy Andromeda is 2.5 million light years away. They estimate there are hundreds of billions to trillions of galaxies. No way of knowing.
Over time we should be able to get increasingly better at detecting signs of life in these distance realms. As Spock would say - it is fascinating.
Can I ask a basic question?
Yes, 137LY is relatively short in astronomical terms, but, in ‘humans travelling there to find our utopia’ terms - tell me how it’s not impossible - if we all saw Tom Cruise have a problem with 10G’s - yes, that’s force 10x greater than the pull of gravity, I get that. But - how is it anatomically possible to travel anywhere near the speed of light - given that we somehow discovered StarTrek technology to do so? Yes, no gravity in space - but the force to go that fast. Wouldn’t we be pink mist?
What am I missing?
If the planet had similar density to Earth but 50% larger radius, you would weigh about 3.3x your current weight, by my calculations.
We would be helpless on that planet but if they came here...
WTH?
Any fifth grader knows it's DIAMETER!
Better?
Since we've 'detected' NOTHING so far...
