For years, exoplanet hunters have been busy searching for planets that are similar to Earth. And when earlier this month, an unnamed source indicated that the European Southern Observatory (ESO) had done just that – i.e. spotted a terrestrial planet orbiting within the star’s habitable zone – the response was predictably intense.

The unnamed source also indicated that the ESO would be confirming this news by the end of August. At the time, the ESO offered no comment. But on the morning of Monday, August 22nd, the ESO broke its silence and announced that it will be holding a press conference this Wednesday, August 24th.

[...]

According to the source cited by the German weekly Der Speigel, which was the first to report the story, the unconfirmed exoplanet is not only believed to be “Earth-like” (in the sense that it is a rocky body) but also orbits within it’s stars habitable zone (i.e. “Goldilocks Zone”).

Because of this, it would be possible for this planet to have liquid water on its surface, and an atmosphere capable of supporting life. However, we won’t know any of this for certain until we can direct the next-generation of telescopes – like the James Webb Space Telescope or Transiting Exoplanet Survey Satellite (TESS) – to study it more thoroughly.

This is certainly an exciting development, as confirmation will mean that there is planet similar to Earth that is within our reach. Given time and the development of more advanced propulsion systems, we might even be able to mount a mission there to study it up close!

The press conference will start at 1 p.m. Central European Time (CET) – 1 p.m. EDT/10 a.m. PDT.

Pretty sure that's a typo on the time conversion and it'll be 7AM US/Eastern or 4AM US/Pacific.

4.5 light years... If humanity can create a spacecraft 2 orders of magnitude faster than our current best we can be there in 800 years!

There's not really any need to go fast given our goals for the past 40 years (unmanned craft using Hohmann transfers). Whatever the practical limit is, past evidence will be less relevant than the laws of physics.

e.g. you can't accelerate much faster than 1g if you want your humans to stay alive,
you have to have enough fuel to brake (turn around and decelerate at the end of the trip)
etc etc
 
So it's the closest star, there's a planet in the habitable zone, and it's a red dwarf meaning very long life (much longer than the sun).

Sounds good lets go.

Space travel and exploration is honestly depressing to think about. Even if we manage to send something there, ever, once it gets there it would still take 4+ years to relay back any information.

Ha! That's what they're thinking too!


Meanwhile, on a message board on Proxima Prime:

certainly an exciting development, as confirmation will mean that there is planet similar to ours that is within reach of glorious empire.

"Ha! That what they're thinking too!"
 
Chances are this will be a Super Earth. I don't believe that we've been able to detect planets similar in size to Earth. Chances are the gravity on this planet will be top high for humans.

8 lightyears is actually not an unreasonable distance in space terms.

If the planet is close enough to Earth-like to be worth looking closer at, we could actually get humans there in a single generation. Sure we'll need better propulsion technology first, but if the planet is hype-inducing enough, then we have a target. And targets are fun when it comes to making crazy ideas suddenly look feasible.

Still, space announcements are rarely as awesome as the previews sound, so let's just wait and see. It would be amazing if it is good enough to warrant a closeup, though. Mankind needs an off-world base to survive in the long run.

Avatar even more confirmed.

What are the odds of a terrestrial planet within the habitable zone existing on the nearest star to ours?
insert conspiracy theory here

But just the right gravity for the Zentradi!

Odds on humans eventually getting to another habitable planet, finding intelligent life that is luckily not as technologically advanced, and proceeding to wipe it out?

Neat if a habitable planet is so close. Not impossible to get to - feasible with some sort of generational ship at least.

Yoo, that shit's huge if true. In the next few years with the JWST, we can detect the chemical composition of smaller exoplanets. This very well may be earth's next home. <3

Actually they have. Kepler 187-f is only marginally (11%) larger than earth and in the habitable zone of the star.

The smallest exoplanet discovered was Kepler 37-b, smaller than Mercury.

It is easier to find close and large planets however.

Hopefully NASA will get increased funding for whatever the JWST's successor might be.
Think about the leap in capability from Hubble to JWST.

Yeah, we're in a wonderful era where generational difference in telescopes increases their power by orders of magnitude.

All that has to happen is Russia or China saying that they're launching a mission to Proxima Centauri. We need another Space Race.

Sailors fighting in the dance hall
Oh man look at those cavemen go
It's the freakiest show
Take a look at the lawman
Beating up the wrong guy
Oh man wonder if he'll ever know
He's in the best selling show
Is there life on Proxima Centauri A?
 
When we send a rover, it'll send back images of a resource depleted planet and sign that reads:

"Sorry we missed you. We've moved next door to the Solar system."

That's really exciting, beyond it being close, since Proxima Centauri should burn a lot longer than the Sun does (being a red dwarf star).
