BREAKING: New potentially habitable exoplanet found around Teegarden's star

[alberto91]

Astronomers have discovered a potentially habitable exoplanet around Teegarden's Star.

Teegarden is an old red dwarf star 12 light-years away in the Aries constellation.

The exoplanet found, called Teegarden b, has a minimum mass almost identical to Earth.

It orbits within the star's habitable zone. And it has a 60% chance of having a temperate surface environment.

Surface temperature should be closer to 28°C assuming a similar terrestrial atmosphere.

Teegarden b is the exoplanet with the highest Earth Similarity Index discovered so far: 95%.

This means that it has the closest mass and insolation to terrestrial values.

Maybe that’s where we originated from, we wrecked the climate there so we came here....to do the same! Our average surface temperature is 14.9c so we’re half way there.

chaz...ever the optimist.

Nice, direct me to nearest wormhole im in.

Great. You can be our advance party. If you survive the first ten minutes, phone home and we'll be right behind you ...

I'm in. Call shotgun.

Okay, so according to Wiki one light year is 5.8 trillion miles, so 12 light years is 69.6 trillion miles.

The Space Shuttle would take 38,263 years to travel one light year, so to get to Teegarden b would only take 459,156 years.

That is without any comfort stops too.

Fascinating  to say the least. The discoveries continue................Dave

(As ever) Youtube Videos set off the "scientific pessimists"? Red dwarfs...
Tidal Locking, Flare Stars etc. etc.  Probably right... but we can dream?  😛

We have "photographed" Pluto. The nearest stars are but 6000x further.
I CAN (just about) imagine a one-way imaging mission as a possibility? 🤔

Daylight is a redder, the plants have black... Life-forms are stocky or 
quadrupedal. I was brought up in the era of cockeyed optimism? 😸

Sooner hopefully rather than later, the concept of it's in the habitable zone, or as it's been termed before, "the Goldie Locks zone", has to be rethought. As long as we continue to look for planets that would support "our life form" the pickings will be somewhat limited.

Who's to say there is not some life form who would be perfectly happy in some atmospheres we could never tolerate?

Once we start thinking in those terms, the possibility for other life in the universe becomes an almost assured possibility. The distances will keep us from knowing.

So what exactly is the process that turns inanimate molecules into life? Without a definitive answer to that, I don't see how that possibility can be "assured".

Dr Frankenstein had it nailed

For a supposedly 'habitable' planets in the Goldilocks Zone, they sound like a pretty weird places. One orbits the star in just 4.9 days, and the other in 11.4, and probably tidally-locked so there would be no concept of a 'day' as the sun would permanently be stationary in the sky. Both are probably bathed in intense solar radiation, permanently baking on one hemisphere and frozen solid on the other. Venus is close to the Goldilocks zone and look what an awful place that is!

Fun to speculate, though.

If ever there was a reason to develop warp drive!

I guess that's one of the great mysteries we still have to figure out. Kind of like the Big Bang.

We do know they both happened, just haven't worked out the exact process.😉
