Astronomers Find What May Be a Habitable World 31 Light-Years Away

If, that is, the exoplanet itself has the right conditions to be conducive to life's emergence.

Yeah, sure.

I wonder just what those 'conditions' are.

Do they have a list?

[Elsie]

All we have to do is vent off the excess heat in the atmosphere

To where?

What about the continuing incoming solar energy that will keep scorching the planet?

[Elsie]

It would be quicker, closer and a better application of resources to terraform Venus, than to chasing off to some far distant star system.

Tell ya what.

As soon as we get our OWN planet cooled off, we can start to work on Venus.

Might have been habitable 31 years ago, but perhaps not if they've since gone woke.

"Our computer simulations show that about 5 percent of all evolving planetary systems around low-mass stars, such as Wolf 1069, end up with a single detectable planet," says astronomer Remo Burn of the MPIA.

And the OTHER 95% do what???

At one light year per minute, it will be an easy commute!

I think the nearest star is about 4 light years away. I saw it illustrated this way. If our sun were a basketball. The earth would be a cherry stone about 3 feet away, and the nearest star would be another basketball, about 140 miles away. 😆

Maybe the dude needs some government grant money.

The earth would be a cherry stone about 3 feet away, and the nearest star would be another basketball, about 140 miles away.

If the nearest star (Proxima Centauri) was 140 miles away, then the nearest galaxy (Andromeda) would be almost 90 million miles away (it is actually 2.5 million light-years away).

[Bubba_Leroy]

there is no way in hell their models and guesstimates can tell if a planet is in a orbital zone that would sustain life from 31 MILLION light years away!!

Plus, unless and until we either actually discover life somewhere else, or figure out how to make a living organism from scratch in a laboratory, we have no idea how life evolves or what conditions are required.

Complex organic molecules are common throughout our solar system and in other systems, but making them is simple. All you need is to take carbon, hydrogen, oxygen, nitrogen and a few other elements, compress them into a confined space with an energy source, and mix them around for a few million years. Gas giants are good for doing that. How to make the jump from the most complex organic molecules to the simplest living organism is a complete unknown.

Ya that too!! ;P

Ok. Just make sure every body goes to the bathroom before you leave, lock up and leave the porch light on.
