The Earth-size planet HD 137010 b has a ‘50% chance of residing in the habitable zone’ of its sun-like star, 146 light-years away, but it may be -70C

So a low possible for the ‘move here’ list?
The point of habitable zone calculations is that liquid water could exist on the surface, so I’m guessing the -70C falls into the other 50%.
Life can exist at -70c, for alien life this might be normal
I get the why, but it is incredibly frustrating we all know there are countless habitable planets out there and we cant see one.
Why aren’t people looking for life via non anthropomorphic methods?
It seems logical in my mind that an advanced civilization wouldn’t operate as an oxygen breathing metabolic meat sack. Highly inefficient.
This is a first earth-sized planet around a sun-like start at earth-like distance. All other detection were around red dwarfs (oversized gas giant-like system rather than proper stars), super earth (probably a water planet)
Minus 70c sounds like the bus stop at Aberdeen beach
Oh, so only 876 trillion miles. It would still take the Enterprise about a month to get there, probably longer tbh.
A couple decades with our AI data centres and it’ll be a nice place to live.
It’s all Canada?
Always has been.
146 years to deliver a message, 292 years to get a reply. Traveling there at about half the speed of light would still take almost three centuries even with time dilation, assuming you weren’t obliterated by a collision with a small rock or ice chunk in transit. Which you most likely would be.
Astronomer here! Everyone is getting excited about this one, but it’s honestly premature. Right now we have only seen *one* transit of this planet in front of its star, meaning it is unconfirmed and the true orbital period (ie year) is unknown, with a range of 300-550 days.
So it is potentially exciting! But we currently do not really know if the planet is a. Real, or b. What its actual temperature is.
Guys normally with exoplanets without knowing the surface conditions they talk about the equilibrium temperature (and maybe a few other assumptions), thats what the -70°C means here. For context Venus equilibrium temperature is -43°C and Earths equilibrium temperature is -18°C
